How Lenders Value Aircraft (And Why It Matters for Your Loan)
TL;DR
Lenders assess an aircraft's security value independently of the purchase price — if their figure is lower, the gap comes out of your pocket, not the loan.
Engine time approaching TBO, damage history, incomplete logbooks, and commercial or leaseback use are the factors that move lender value down most significantly.
LVRs for private aircraft typically sit at 70–80%; commercial use, older types, or complex ownership structures push that deposit requirement higher.
If a valuation comes in below the purchase price, your options are renegotiating with the seller, funding the shortfall yourself, or finding a lender with a more favourable assessment.
There is a common assumption among first-time aircraft buyers that if the seller agrees to a price and the bank approves your income, the loan will follow. It is a reasonable assumption. It works that way with cars. It often works that way with commercial property.
But with aircraft finance in Australia, it regularly does not work that way — and borrowers who discover that late in the process can find themselves out of pocket, out of time, or out of a deal entirely.
The reason is that aircraft lenders are not just assessing you. They are assessing the aircraft as a security. And their view of what that aircraft is worth may differ significantly from what you have agreed to pay. That gap — between the agreed purchase price and the lender's assessed security value — is one of the most common and most expensive surprises in aircraft finance. Understanding how lenders arrive at their valuation, what drives it up or down, and what it means for your borrowing power is the foundation of any well-prepared aircraft finance application.
If you are comparing lenders, buying your first aircraft, or trying to work out how valuation, deposit requirements, and ownership structure could affect your borrowing power, it can help to speak with a broker who understands the aviation market rather than general asset finance. Our aircraft finance specialists can help you understand how different lenders are likely to assess the aircraft and what that means for your loan options before you commit to a purchase.
Why purchase price and lender value are not the same
These are not the same thing, and confusing them is the first mistake many buyers make.
What the purchase price represents
When you negotiate a price with a seller, that price reflects what the two of you have agreed the aircraft is worth in that transaction. It might reflect current market conditions, the seller's urgency, the aircraft's recent upgrades, or simply the outcome of a negotiation. It is a commercial agreement between a buyer and a seller.
What the lender value represents
When a lender assesses the aircraft, they are doing something different. They are determining what the aircraft would likely realise if it had to be sold quickly in a distressed scenario — what is often called the forced-sale value or the security value. Lenders are generally not investing in your aircraft. They are taking it as collateral against a loan, and they need to know that if you stopped making repayments tomorrow, they could recover their exposure by selling the aircraft without absorbing a significant loss.
Why lender value often sits below the purchase price
That means lender value is almost always at or below the market rate, and sometimes meaningfully below it. A well-maintained aircraft with a clean history and broad market appeal will tend to achieve a lender valuation close to its sale price. An older aircraft with incomplete logbooks, a significant damage history, unusual modifications, or a limited resale market may receive a lender valuation materially lower than what the seller is asking — regardless of what you and the seller have agreed is fair.
What a valuation gap means in practice
If the lender's assessed value is $280,000 and you have agreed to pay $320,000, the lender will structure the loan against $280,000. The $40,000 difference becomes your problem. You will need to cover it from your own funds in addition to any required deposit — or renegotiate the purchase price, or find a lender whose assessment is more generous.
How lenders actually value an aircraft
Aircraft lenders in Australia and internationally draw on a combination of market guides, documentation review, and in some cases formal third-party appraisals. Understanding each of these helps you anticipate where your aircraft might be assessed and why.
Market valuation guides
The aircraft finance industry uses specialist pricing databases that track market values by make, model, year, and configuration. These guides function similarly to pricing guides for motor vehicles — they provide a reference point for what a particular aircraft type is selling for in a given market at a given time. Lenders often use these as a starting point before any further analysis.
The issue is that guide values are averages. They tell you what a typical example of that aircraft model might be worth. They do not account for this specific aircraft's logbook hours, maintenance currency, installed avionics, damage history, or the depth of demand for that particular type in the current market.
Documentation and logbook review
For most aircraft finance transactions, lenders will want to see the aircraft's maintenance records and logbooks. These are not just administrative documents. They are the primary evidence of how the aircraft has been operated and maintained over its life. A complete, well-kept logbook record tells the lender that the aircraft's history can be verified. Gaps in the logbook — missing entries, undocumented work, or periods of unknown operation — introduce risk, because the lender cannot fully assess what may have happened to the aircraft during those periods.
Engine and propeller logbooks matter separately. The time since last major overhaul, whether the engine is on a manufacturer's recommended overhaul schedule, and whether any major unscheduled work has been carried out can all affect both insurability and lender value.
Formal appraisals
For higher-value aircraft, less common types, or where there is any ambiguity around condition or history, lenders may require a formal independent appraisal by an accredited aviation appraiser. A thorough appraisal goes beyond a visual inspection — it typically covers a review of logbooks, maintenance records, equipment and avionics, airworthiness directives compliance, installed modifications, and a physical inspection of the airframe. The appraiser produces a written report that gives the lender a documented, defensible assessment of value.
It is worth knowing that appraisals cost money — typically several hundred to several thousand dollars depending on aircraft type and geographic location — and that cost is usually borne by the borrower. Budget for it from the outset.
Comparable sales analysis
Experienced aviation lenders and appraisers will also consider comparable recent sales for the same or similar aircraft types. For popular models with an active Australian resale market, this is relatively straightforward. For niche or rare types — older turboprops, unusual experimental-to-certified conversions, or specialised agricultural aircraft — there may be very few comparables available, which itself becomes a risk factor for the lender.
What affects lender value most
Lenders and appraisers adjust their assessment of an aircraft's value based on a range of aircraft-specific and market factors. These are the ones that tend to move the number most significantly:
Total airframe time
Higher total time means more cycles on the airframe and, in general, a lower assessed value. This is not absolute — a well-maintained, low-utilisation aircraft with high hours may still appraise well — but total time is one of the first data points a lender looks at.
Engine time since overhaul
An engine approaching its recommended time before overhaul (TBO) is a known liability. The cost of a major overhaul can range from tens of thousands to hundreds of thousands of dollars depending on engine type. Lenders factor this in. An aircraft with engines recently overhauled to zero hours is in a materially different position to an aircraft with the same engines running close to TBO. Some lenders will reduce their assessed value to account for the estimated overhaul liability, effectively requiring you to hold a larger deposit.
Damage history
This is probably the single most consequential factor after age and time. An aircraft that has been involved in a significant accident — even if it was repaired to an airworthy standard and approved for return to service — will carry a reduced assessed value with most lenders. The reasoning is not that repaired aircraft are necessarily unsafe. It is that they are harder to resell, attract a narrower pool of buyers, and may face insurance complications.
Some lenders will decline to finance aircraft with certain categories of damage history entirely. Others will finance but at a lower loan-to-value ratio (LVR) or with additional conditions. Knowing your aircraft's history before you apply — and understanding how your lender treats that history — is essential preparation.
Avionics and installed equipment
A well-specced instrument panel with modern avionics can add material value to an aircraft, both in resale terms and in the lender's assessment. Conversely, an aircraft with outdated avionics or missing equipment that buyers in the current market expect as standard may be valued below a comparable aircraft with better equipment. The key is whether the avionics are accurately documented — an expensive avionics upgrade that is not recorded in the aircraft's technical documentation may not be recognised in the valuation at all.
Modifications and Supplemental Type Certificates (STCs)
Modifications can add value or complicate it. A well-documented STC installation from a reputable source that broadens the aircraft's capability may be recognised positively. Undocumented or unusual modifications raise questions that lenders do not want to answer on your behalf.
Intended use
An aircraft used exclusively for private, recreational flying is a different lending proposition to an aircraft operated under a leaseback arrangement with a flight school, used for charter, or operated in a revenue-generating role. Commercial use typically means higher hours, more wear, a different maintenance and insurance environment, and a different regulatory context.
Most aircraft lenders adjust their terms — sometimes significantly — for commercial or leaseback use. In some cases, lenders who are comfortable with private aircraft finance will decline commercial-use applications entirely and refer the transaction to a specialist commercial asset funder.
Ownership structure
Whether you are buying in your personal name, through a company, or through a trust structure affects both the documentation requirements and the lender's assessment of risk. Entity borrowers typically require more documentation, director guarantees, and in some cases a more conservative LVR. Deciding on your ownership structure before you approach lenders — not after — is important because changing it mid-application can reset the process and cause material delays.
Market liquidity for the type
A Cessna 172 or Piper Cherokee has a deep, active resale market in Australia. A lender knows that if they had to sell a repossessed example, they could find a buyer reasonably quickly. An unusual or niche type — a very old airliner repurposed for private use, a specialised agricultural aircraft, or an aircraft with limited parts availability — is harder to liquidate. That difficulty translates directly into a more conservative valuation and, often, a lower LVR.
How valuation connects to your actual loan
Understanding valuation only matters if you can connect it to the numbers on your loan offer. Here is how the chain works in practice.
Lenders in the aircraft finance space typically lend up to a maximum loan-to-value ratio (LVR) based on the lower of the purchase price or assessed security value. For private-use aircraft from established lenders in Australia, LVRs typically sit in the range of 70–80% of assessed value, meaning deposits of 20–30% are standard. For older aircraft, niche types, commercial use, or borrowers with more complex profiles, the required deposit may be higher.
What this means practically: if the lender assesses your aircraft at $300,000 and is willing to lend at 75% LVR, the maximum loan is $225,000 and the minimum deposit is $75,000. If you have agreed to pay $320,000 for the aircraft, your required cash contribution is $95,000 — not $75,000. The $20,000 valuation shortfall comes out of your pocket.
Valuation also affects pricing. Most aircraft lenders apply a risk-based approach to interest rates. Lower LVR, stronger security, and a cleaner aircraft profile typically attract better pricing. Higher LVR or higher-risk security may attract a risk margin. This is not always large, but over a 5 or 10-year loan term, it adds up.
Loan term restrictions are also worth understanding. Some lenders cap loan terms for older aircraft or limit the age the aircraft can reach at the end of the loan term. If you are buying a 1980s aircraft and the lender's policy caps the aircraft's age at end of term to 40 years, you may find the maximum available term is shorter than you expected — which increases the monthly repayment.
What happens when valuation comes in below the purchase price
This situation is more common than buyers expect, and having a plan before it happens is far better than improvising when the appraisal report lands. Your options in this scenario are broadly:
Renegotiate the purchase price
If the aircraft has appraised materially below the agreed price, you have factual grounds to go back to the seller. A professional appraisal is not a subjective opinion — it is a documented, expert assessment of value. Many sellers, particularly private sellers motivated to complete the transaction, will negotiate when presented with a formal appraisal that supports a lower price. This is the cleanest outcome and the one most worth pursuing first.
Bridge the gap from your own funds
If the seller will not move and you still want the aircraft at the agreed price, you need to fund the valuation shortfall from your own resources in addition to the standard deposit. Make sure this is a deliberate, well-considered decision — not a purchase you are overpaying for because you have already become emotionally committed.
Find a lender with a more favourable view
Not all lenders value the same aircraft the same way. Some specialists in aviation lending apply a more granular analysis of market conditions, avionics, and maintenance status than others. A broker who works regularly in aircraft finance can identify which lenders are likely to assess a particular aircraft more generously, and can sometimes avoid a shortfall situation entirely by starting with the right lender.
Walk away
Sometimes the valuation is telling you something important. If the lender's assessment is significantly below the asking price, it is worth asking whether the aircraft is overpriced relative to its actual condition and market value. A valuation shortfall is not always a financing problem. It can be a purchase decision problem.
What Australian borrowers need to understand about aircraft finance
Aircraft finance in Australia does not sit neatly in one lending category, and the regulatory context that applies to your loan depends on how the aircraft will be used and how you are structured as a borrower.
Personal and recreational use
If you are buying an aircraft for personal, recreational use as an individual, the transaction may fall within the scope of consumer credit regulation under the National Consumer Credit Protection Act and be subject to the responsible lending obligations administered by the Australian Securities and Investments Commission (ASIC). That means your lender is required to assess whether the loan suits your circumstances — a meaningful borrower protection, but also a source of documentation requirements and assessment rigour.
Business and commercial use
If you are purchasing through a company or trust for genuine business purposes — flight training, charter, agricultural use, or business travel — the transaction is more likely to be treated as commercial asset finance, outside the consumer credit framework. The lender still has obligations, but they are different in nature, and the loan documentation and assessment process will reflect that. The Australian Financial Complaints Authority (AFCA) also handles complaints differently depending on whether a loan is consumer or small-business lending.
What this means practically is that getting the structure right before you apply — and understanding how your intended use will be characterised — can affect both the loans available to you and the regulatory protections you have. A good aircraft finance broker can help you think through this clearly before you commit to an approach.
It is also worth noting that the number of Australian lenders with genuine aircraft finance expertise is small. The major banks generally do not have specialist aviation lending teams, and borrowers who approach them directly often find that standard equipment finance or personal loan products are offered instead — sometimes at less favourable terms, and sometimes structured in ways that do not properly account for aircraft-specific risk or valuation nuance.
Specialist aviation lenders and experienced finance brokers who work in this space regularly are typically a better starting point.
How valuation plays out in real scenarios
The following scenarios illustrate how valuation and lender assessment play out in common aircraft finance situations Australian borrowers may encounter.
Scenario 1 — The first-time private buyer
A recreational pilot agrees to purchase a 1998 single-engine piston aircraft for $185,000. The aircraft has around 4,200 hours total time, engines approaching TBO, and a full logbook history. The purchase price seems reasonable based on online listings. The lender orders an appraisal and comes back with a security value of $155,000 — $30,000 below the agreed price — primarily because the engine overhaul liability has been factored in. The borrower's options are: negotiate the price down with the seller, fund the shortfall in addition to the deposit, or walk away. In this case, the borrower used the appraisal to negotiate the price down to $160,000, which the lender accepted, and the loan proceeded on acceptable terms.
The lesson: engine time is a cost, not just a maintenance issue, and it affects your financing.
Scenario 2 — The company purchase with a leaseback arrangement
A flight school operator purchases a new light aircraft through a proprietary company with plans to leaseback the aircraft to the school for student training. The purchase price is $420,000. The lender, on being informed of the leaseback arrangement and intended commercial use, adjusts the available LVR down to 65% — meaning the required deposit increases from around $84,000 to $147,000. The interest rate also carries a small commercial-use premium.
The lesson: if you plan any commercial use, know how your lender treats it before you make offers or budget your cash position.
Scenario 3 — The refinance after upgrades
An aircraft owner has owned a twin-engine piston aircraft for several years and has recently invested $45,000 in an avionics upgrade — a new glass cockpit installation with full documentation and STCs. The owner wants to refinance to access equity. The lender's appraisal acknowledges the avionics upgrade but does not attribute the full cost to added security value; the appraised value increases by around $30,000 relative to the pre-upgrade estimate. The refinance proceeds, but the borrower learns that capital invested in upgrades does not always translate dollar-for-dollar into increased security value.
The lesson: upgrade documentation matters, but upgrades are an investment in usability and enjoyment, not necessarily a guaranteed equity builder.
Scenario 4 — The aircraft with undisclosed damage history
A borrower makes an offer on a well-presented aircraft and applies for finance. During the lender's assessment process, a check of aviation safety records reveals a previously undisclosed incident — a hard landing that resulted in structural inspection and repair several years prior. The incident was repaired and signed off, but the seller had not disclosed it. The lender adjusts the assessed security value downward by 15% and requires additional inspection documentation before proceeding. The purchase still completes, but at a lower LVR and with conditions.
The lesson: always commission an independent pre-purchase inspection and check available safety and incident records before applying for finance, not after.
How the aircraft finance process works step-by-step
Understanding where valuation sits in the process helps you sequence your decisions correctly.
Step 1 — Initial enquiry and pre-assessment
Before you make any offers, speak with a broker or lender about your borrower profile — income, cash available for deposit, ownership structure, and intended use. Get a realistic sense of what you can borrow and what deposit you will need. This is the stage where you can also get clarity on how your lender treats commercial use, entity borrowers, and older aircraft types.
Step 2 — Aircraft selection
Once you know your borrowing capacity and deposit range, you are in a much stronger position to evaluate potential aircraft. At this stage, your broker can give you an indicative sense of how a particular aircraft type is likely to be viewed by lenders — including any known policy restrictions on age, use, or type.
Step 3 — Pre-purchase inspection and valuation
Before signing contracts, commission an independent pre-purchase inspection from a qualified aircraft maintenance engineer, and understand whether a formal appraisal will be required by your lender. In many cases, the lender will order the appraisal themselves or specify the appraiser to be used. Budget the appraisal fee into your upfront costs.
Step 4 — Formal application
With an aircraft identified and an inspection complete, the formal application is submitted. This will typically include your financial statements or tax returns, identification, entity documentation if applicable, the contract of sale, and the aircraft's maintenance records and logbooks. Incomplete documentation is one of the most common causes of delay — gather everything before lodging.
Step 5 — Credit assessment and valuation
The lender assesses both you and the aircraft. Underwriting typically takes 5–10 business days for straightforward applications, longer for complex entity structures or aircraft requiring detailed appraisal. You will receive either a formal approval, conditional approval, or a decline.
Step 6 — Insurance
Most lenders will require evidence of hull and liability insurance before settlement. The aircraft must be insured in a way that meets the lender's requirements, and the lender will typically need to be noted on the policy as an interested party. Arrange this early — insurers sometimes require their own inspection or have questions about maintenance status.
Step 7 — Settlement
Once all conditions are met, the loan settles, funds transfer to the seller, and ownership is transferred. Depending on the type of aircraft and the security arrangement, the lender may register a security interest over the aircraft.
What to budget for beyond the repayment
Aircraft finance has a broader cost profile than most borrowers initially factor in. Going in with eyes open avoids post-purchase financial stress.
Deposit
The deposit will typically be your largest upfront cost — 20–30% of assessed value for a standard private purchase, potentially higher for commercial use, older types, or complex ownership structures.
Appraisal and inspection fees
Appraisal and inspection fees are usually in the range of several hundred to a few thousand dollars depending on aircraft type and where the aircraft is located relative to the appraiser.
Lender and broker fees
Lender establishment fees and any applicable broker fees should be factored in. Broker fees are typically structured as a percentage of the financed amount; a qualified broker's value in navigating lender selection, valuation risk, and application quality usually more than offsets this cost.
Insurance
Insurance is typically a non-negotiable ongoing cost. Hull insurance on an aircraft used for private flying will depend on the aircraft's value, the pilot's experience and recent hours, and the intended use profile. Get quotes early in the process.
Hangarage and tie-down costs
Hangarage or tie-down costs are a significant ongoing expense that many first-time buyers underestimate, particularly in capital city airports where demand for hangar space is high.
Maintenance reserves
Maintenance reserves — setting aside funds each month to cover scheduled and unscheduled maintenance, annual airworthiness inspections, and eventual engine overhaul — are a financial discipline that distinguishes organised aircraft owners from those who face sudden, large, unexpected bills. A common approach is to calculate the estimated cost of the next major overhaul and divide it by the remaining hours.
Registration and regulatory compliance
Registration, navigation charges, and any regulatory compliance costs vary by aircraft category and use.
What mistakes to avoid
Based on how applications actually unfold, these are the errors that cost borrowers the most time, money, and frustration:
Assuming the purchase price equals the lender value
This is probably the most consequential error — and the one most worth guarding against.
Changing ownership structure or use plan mid-application
Deciding after submission that you want to hold the aircraft in a company rather than personally, or that you will add a leaseback arrangement, can require the application to be substantially reworked. Make these decisions before lodging.
Failing to disclose damage history
Lenders conduct their own checks. Incomplete or inaccurate disclosure of damage history damages your credibility and can lead to worse outcomes than a straightforward upfront disclosure would have.
Going to a non-specialist lender
Aircraft finance is genuinely specialised. A general bank or consumer lender offering you a personal loan or standard equipment finance product may not be applying an appropriate valuation methodology or structuring the loan correctly for an aviation asset. The short-term convenience of a familiar banking relationship often produces inferior outcomes in this asset class.
Not budgeting for the full cash requirement
The deposit is not your only upfront cost. Appraisal fees, inspection fees, insurance premiums, registration costs, and the potential valuation shortfall all require cash. Many buyers who have the deposit organised are caught short by these additional items.
Making an emotional commitment before finance is confirmed
The ideal sequence is: understand your borrowing capacity first, then find aircraft, then make a conditional offer. Agreeing to buy an aircraft before understanding the likely finance terms puts you in a weak position if the valuation or approval does not go as expected.
The Bottom Line
Aircraft finance is not complicated in principle, but it is nuanced in practice. The variable that most catches buyers off guard — and the one that most directly affects how much they can borrow, how much deposit they need, and whether the transaction proceeds at all — is not their income, their credit score, or the interest rate. It is the lender's independent assessment of what the aircraft is worth as security.
Approaching aircraft finance with a clear understanding of how that assessment works, which aircraft characteristics move it up or down, and how to manage the gap between purchase price and lender value puts you in a substantially better position than borrowers who discover these mechanics after they have already signed a contract.
Get the structure right, prepare the documentation thoroughly, and work with advisers who know this asset class — the rest of the process becomes much more manageable.

Frequently Asked Questions (FAQs)
How do lenders decide what an aircraft is worth?
Lenders typically use a combination of specialist market pricing guides, logbook and maintenance documentation review, and in some cases a formal independent appraisal. The assessed value reflects what the lender believes the aircraft would realise in a resale scenario, which may differ from the price you have agreed to pay.
Is the lender value the same as the purchase price?
Not necessarily. Lenders typically assess the aircraft independently of the purchase price. If their assessed security value is lower than what you have agreed to pay, the lender will base the loan on their assessment — and the difference becomes your responsibility.
Do lenders always require a formal appraisal?
Not always. For some straightforward transactions involving well-known aircraft types in good condition, a lender may rely on market guides and documentation review. For higher-value, older, or less common aircraft, or where there is any ambiguity around condition or history, a formal appraisal is typically required.
What reduces an aircraft's lender value the most?
Significant damage history, engines approaching time before overhaul, incomplete or inconsistent logbooks, unusual modifications, commercial or leaseback use, and limited resale market for the type are the most impactful negative factors.
Can I get finance for an older aircraft?
Yes, but lenders apply more conservative policies to older aircraft. LVR limits may be lower, loan terms shorter, and the list of lenders willing to finance the transaction may be smaller. Condition and documentation quality become even more important for older aircraft.
Does damage history automatically mean the loan will be declined?
Not automatically, but it depends on the nature and extent of the damage. Minor, well-documented incidents that were properly repaired are treated differently to major structural damage or events involving significant airworthiness concerns. Some lenders will finance aircraft with damage history at a reduced LVR; others will not finance at all depending on the category of incident.
How much deposit do I typically need?
For private-use aircraft, a deposit of 20–30% of assessed value is typical in the current market. Commercial use, older aircraft, complex ownership structures, or a less common aircraft type may require a higher deposit. Budget conservatively and confirm with your lender or broker before making offers.
Can I buy through a company or trust?
Yes. Entity purchases are common in aviation. They typically require additional documentation — financial statements, entity documents, director guarantees — and may be assessed on slightly different terms to individual borrowers. The structure should ideally be decided and disclosed before application, rather than changed partway through.
Does commercial or leaseback use change the loan?
Yes, often significantly. Commercial use typically results in a lower LVR, potentially higher interest rate, different documentation requirements, and a narrower range of available lenders. Some lenders do not finance commercial-use aircraft at all.
What happens if the valuation comes in below the purchase price?
You have three options: renegotiate the purchase price with the seller, fund the shortfall from your own resources, or find a lender whose assessment is more favourable. A broker can help you evaluate which path makes most sense for your situation.
Can I refinance an aircraft I already own?
Yes. Refinancing is common where owners have paid down a loan significantly, made material improvements to the aircraft, or want to access equity. The lender will typically conduct a fresh assessment of the aircraft's current security value. Keep documentation and logbooks current — a refinance assessment is not more lenient than an original purchase assessment.
Is aircraft finance treated as consumer lending or business lending in Australia?
That depends on the borrower and the purpose. Personal recreational use as an individual borrower typically falls within the consumer credit framework under the National Consumer Credit Protection Act. Business-purpose borrowing through a company or trust is generally treated as commercial asset finance. The applicable framework affects both lender obligations and borrower protections.
Should I go directly to a lender or use a broker?
Using a broker with genuine aircraft finance experience is typically the better approach. The number of Australian lenders with specialist aviation lending capability is small, and lender policies vary significantly by aircraft type, age, use, and borrower structure. A good broker knows which lenders are likely to take a favourable view of your aircraft and your profile, can help you prepare documentation correctly, and can navigate valuation issues before they become problems.
