Structuring Aircraft Ownership Without Impacting Your Borrowing Capacity
TL;DR
Aircraft debt — whether personal, company-owned, or in a trust — almost always affects your borrowing capacity if a personal guarantee is involved, because lenders look through entity structures.
A loan that's comfortably affordable in real cashflow can still significantly reduce your assessed borrowing capacity, because lenders apply a stress-tested rate buffer to all liabilities.
Tax deductions on aircraft expenses reduce taxable income, which can also reduce the net income figure lenders use — the opposite of what most borrowers expect.
Speak to a mortgage broker before choosing an ownership structure, not after — timing and structure decisions are far easier to get right at the start.
Most people who ask about buying an aircraft are not really asking about the aircraft. What they are actually asking is: if I do this, what happens to my ability to borrow money later?
It is a legitimate concern. Whether you are planning to buy a home in 12 months, refinance an investment portfolio, or keep your lending options open for a business purchase, an aircraft acquisition can have real consequences on how a lender assesses your financial position — consequences that are rarely spelled out clearly anywhere.
The standard advice is to talk to a lawyer, an accountant, and a finance broker. That is good advice. But most borrowers want to understand the landscape before those conversations, so they can ask the right questions rather than relying entirely on others to steer them.
This article explains how aircraft ownership interacts with mortgage lending and borrowing capacity in Australia, what lenders are actually looking at, and how to structure your ownership so that your aviation goals do not quietly undermine your property or finance goals.
The lender's view of borrowing capacity
Borrowing capacity, or serviceability, is a lender's assessment of whether you can comfortably meet your repayment obligations without financial hardship. It is not simply a question of whether you earn enough. It is a calculation that weighs your income against your liabilities, living expenses, and a stressed interest rate.
Australian authorised deposit-taking institutions (ADIs) — your banks and credit unions — are expected by the Australian Prudential Regulation Authority (APRA) to assess home loan applications using a buffer of at least 3.0 percentage points above the loan rate. That means if you are applying for a loan at 6.5%, the lender tests whether you could afford repayments at 9.5%. That buffer alone can substantially reduce the loan amount you qualify for.
On top of the rate buffer, lenders deduct your existing debt commitments from your surplus income. This is where aircraft ownership becomes directly relevant. Any loan repayment, lease liability, personal guarantee, or ongoing financial commitment that a lender can see — or is obliged to inquire about — reduces your assessed surplus and therefore your borrowing capacity.
The key distinction borrowers often miss is this: a loan might be entirely affordable in your day-to-day cashflow, but still reduce your assessed borrowing capacity by more than you expect, simply because the lender applies a buffer rate to the repayment and counts it as a fixed obligation.
Aircraft ownership structures and lending impact
The most common question brokers hear is: "If I buy the aircraft through a company, will the bank still count it against me?" The honest answer is: it depends, and often yes. The way you hold the aircraft — personally, through a company, through a trust, or through a special-purpose entity — affects how a future lender will see your position. The 4 common ownership structures each have different implications:
Personal ownership
Buying an aircraft in your own name is the most straightforward from a lending perspective, and also the most directly impactful on serviceability. The loan appears on your credit file. The repayments are counted as a liability by every lender. There is no ambiguity about whose obligation it is.
For borrowers planning a property purchase within the next 1 to 2 years, personal aircraft ownership with a significant loan in their own name is the structure most likely to create serviceability friction. It is simple and clean from a legal standpoint, but it leaves the debt fully visible and fully counted.
On the positive side, personal ownership typically involves less complexity when it comes to aircraft finance approval itself. Lenders can assess you directly. There are fewer documentation hurdles, and there is no entity structure to scrutinise.
Company ownership
Company ownership is often presented as a way to quarantine the aircraft debt from personal finances. In practice, it is more nuanced than that.
If you are a director of the company that owns the aircraft, most lenders will ask whether you have provided a personal guarantee for the debt. If you have — and for closely held companies, lenders frequently require it — that guarantee can be treated as a contingent liability in your personal serviceability assessment. Some lenders will add the full guaranteed amount to your liabilities. Others may take a more measured view if the company's financials demonstrate that the business is comfortably servicing the debt from its own income.
From a broker's perspective, lender policy varies considerably here. Some credit teams will look through to the company's profit and loss and accept that the debt is well-covered. Others will mechanically add the repayment to your personal obligations regardless. That variability is exactly why lender selection matters when you are in this situation — and why getting broker advice before you sign anything is important, not after.
Company ownership also introduces complexity around income assessment. If your income flows through the company — as dividends, director fees, or distributions — lenders will typically require 2 years of tax returns and financial statements to average and assess that income. Any aircraft-related expenses run through the company will reduce the net profit figure lenders use, which can affect how much income is recognised.
Trust ownership
Trust structures add another layer of complexity. The key questions for a lender are who controls the trust, who benefits from it, and who has guaranteed any associated debt. A trustee company owned by the same individual who wants a home loan is generally not treated as a firewall by experienced credit assessors — it is a related entity, and most credit teams will recognise that.
Trusts can offer genuine asset protection and succession planning benefits. But from a pure borrowing-capacity perspective, they rarely shield a borrower from having the aircraft debt counted in some form, particularly where a personal guarantee has been given or where the borrower is both trustee and sole beneficiary.
Discretionary trusts also create income assessment challenges for mortgage applications, because distributions are at the trustee's discretion and lenders may not accept the full distribution amount as reliable ongoing income without 2 or more years of consistent distribution history.
Special-purpose and fractional ownership
For borrowers purchasing through a joint ownership arrangement or a special-purpose vehicle, the key questions are the same: is there a personal guarantee, and does the lender have visibility of the obligation? Co-ownership arrangements can also create complications if one co-owner's financial difficulties affect the entity's loan, potentially triggering cross-default clauses that touch the other owner's personal guarantee.
Fractional ownership, where you purchase a share in an aircraft managed by a third party, may have different lending implications depending on whether the arrangement involves a financing commitment in your name or a contractual payment obligation that a lender might count as an ongoing expense.
The costs that most borrowers overlook
Aircraft ownership involves more than a loan repayment. Beyond the regular repayment, there are several categories of ongoing costs that a thorough lender may factor into your overall financial position:
The full cost stack of aircraft ownership
The total cost stack typically includes insurance premiums, scheduled and unscheduled maintenance, hangarage or tie-down fees, registration, fuel, pilot wages or training costs if applicable, and management fees if the aircraft is operated commercially. In Australia, these costs are not trivial.
Lender treatment of ongoing aircraft expenses
Residential lenders conducting responsible lending assessments are required by law to make reasonable inquiries about a borrower's financial situation. A broker who knows you own an aircraft is likely to ask about ongoing costs — and a thorough credit assessor may factor declared aircraft expenses into their living expense assessment, especially if they appear in bank statements or tax returns.
The indirect effect on your property deposit
If purchasing an aircraft has absorbed a significant portion of your liquid savings, you may find yourself with a smaller deposit for a future property purchase. A smaller deposit means a higher loan-to-value ratio (LVR), which may mean Lenders Mortgage Insurance (LMI) applies, a higher interest rate, or reduced lender choice. None of that is fatal, but it is worth modelling before committing capital to an aviation purchase.
When aircraft ownership is most likely to hurt your borrowing position
Not every aircraft purchase creates a serviceability problem. But the following situations may increase the risk:
Buying in your own name shortly before a property application
This is probably the highest-risk scenario. The timing means the debt is fresh, fully visible, and fully counted — with no opportunity to demonstrate that it has not affected your financial position over time.
Giving a personal guarantee to an underfunded entity
If the company or entity is not generating income sufficient to cover the aircraft loan from its own resources, the full weight of that repayment falls onto your personal serviceability assessment.
Relying on charter or lease income in a mortgage application
Using commercial or charter income to offset the aircraft loan does not always work as expected. Lenders assess rental and lease income conservatively, applying a discount. Charter income from an aircraft may be treated even more conservatively or not accepted at all by some lenders, particularly if the income is irregular or the aircraft has only recently commenced commercial operation.
Stacking an aircraft commitment on multiple existing property debts
Multiple existing property debts, combined with an aircraft commitment, can compound quickly. If you are already carrying 4 or 5 investment property loans, adding an aircraft repayment — even through a company structure — may push your debt-to-income position past the comfort level of many lenders.
Real borrower scenarios
The following 4 scenarios illustrate how borrower circumstances and structure choices shape the outcome of a mortgage assessment after an aircraft purchase:
Scenario 1 — High-earning GP planning a first home purchase
Consider a GP who earns $350,000 per year and wants to purchase a light aircraft for personal travel. She also plans to buy her first home in 14 months. If she finances the aircraft personally with a $180,000 loan at a 9% assessed rate, the lender's serviceability calculator will treat that as an approximately $1,700 per month liability under stress testing. Depending on her living expenses and the home she wants to buy, that single commitment could reduce her maximum home loan capacity by $200,000 to $250,000 — not because she cannot afford it, but because the calculation works that way.
Scenario 2 — Business owner with a company-held aircraft loan
A business owner purchasing through a company structure with a $400,000 aircraft loan, where he has given a personal guarantee, approaches a bank for a commercial property purchase 6 months later. His broker submits to a lender that reviews the company's financials and accepts that the company is comfortably covering the aircraft debt from trading income. A different lender, applying a more conservative policy, loads the full $400,000 as a personal liability. The choice of lender in that scenario makes a material difference.
Scenario 3 — Property investor refinancing with an aircraft in a family trust
An investor holding 7 properties approaches her broker about refinancing to release equity. She purchased an aircraft through a family trust 2 years earlier and gave a guarantee. Her trust distributions over the past 2 years have been inconsistent. The bank assessing her refinance cannot use the distributions as reliable income, but does count the guarantee. That combination — reduced assessable income plus an additional contingent liability — results in the refinance being declined at the loan amount she needed. A restructured application to a non-major lender, with different income assessment methodology, eventually succeeds, but the process takes longer and costs more than anticipated.
Scenario 4 — High-income PAYG borrower with stacked personal debts
A high-income Pay As You Go (PAYG) borrower earns $280,000 per year working for a mining company. He can genuinely afford the aircraft repayments in his actual cashflow. But after HECS-HELP debt, an existing car loan, a personal loan, and now the aircraft financing, his assessed surplus income under a stress-tested rate is thin enough that the major bank he approaches declines his home loan application. The solution is not structurally complex — paying out the car loan and personal loan before applying may improve the servicing position — but it is the kind of sequencing issue that a broker should identify before any applications are lodged.
How to structure aircraft ownership more strategically
There is no single correct structure for aircraft ownership. The right approach depends on your tax position, asset protection goals, the nature of the aircraft's use, and — critically — your property and lending plans over the next 2 to 3 years. The following framework helps you think through the decision before engaging your advisers:
Map your property goals first
If you intend to buy, refinance, or make substantial changes to your property lending within the next 18 months, that timeline should drive the aircraft ownership decision, not the other way around. The aircraft purchase may still proceed, but the structure and timing should be chosen with the lending impact in mind.
Stress-test serviceability before committing
Before signing an aircraft finance contract, ask your broker to model your maximum borrowing capacity with and without the aircraft liability included. That calculation, run across a few lenders with different assessment methodologies, will show you the real cost of the acquisition in lending terms.
Understand the guarantee position fully
If you are purchasing through a company or trust and the lender is requiring a personal guarantee, you need to know how each lender you might approach in future will treat that guarantee. Some will count it in full. Others may not if the associated entity demonstrates its own debt-servicing capacity. That assessment is lender-specific and changes over time as lender policy evolves.
Avoid changing ownership structure mid-transaction
Shifting from personal to company ownership part-way through an aircraft finance application — or doing a related restructure during a concurrent property loan application — creates complexity that can delay or derail approval. Structure decisions should be made cleanly before either process begins.
Keep your advisory team aligned
Your mortgage broker, accountant, and any aviation or commercial lawyer involved should understand each other's constraints. Tax optimisation choices made by an accountant, if implemented without consideration of lender documentation requirements, can create income assessment problems down the track. A broker who sees the full picture before any entity or finance structure is finalised can flag those issues early.
If you are still weighing up whether to buy now or delay the purchase until after a property application, it can help to speak with a broker who understands aviation finance. This is especially relevant if you are comparing personal, company, or trust ownership, or trying to work out whether an aircraft loan, guarantee, or related costs could complicate a home loan, refinance, or commercial property purchase down the track.
Common mistakes and misconceptions
Several misconceptions can lead borrowers to underestimate how aircraft ownership affects their mortgage position. The most common ones to watch for are:
Assuming a company-owned aircraft disappears from your personal picture
A company-owned aircraft does not simply disappear from a borrower's personal financial picture. As discussed above, guarantees and related-entity liabilities mean that most lenders retain some visibility of the obligation, and experienced credit assessors are trained to look for it.
Believing tax deductions improve borrowing capacity
Tax deductions generally do not improve borrowing capacity. They reduce your taxable income, which in many cases also reduces the net income figure a lender will use in serviceability calculations. The aircraft-related deductions your accountant is legitimately claiming may reduce the income figure available to lenders.
Treating a business-purpose loan as separate from your personal position
Some borrowers assume that a business-purpose aircraft loan is treated entirely separately from consumer lending and has no impact on a personal mortgage application. In practice, a personal guarantee on a commercial facility typically creates a personal liability. The nature of the loan does not alter that.
Expecting lease or charter income to fully offset the repayment
A persistent belief is that lease or charter income will fully offset the aircraft repayment in a mortgage assessment. That is rarely the case. Lenders apply discounts to investment income of all kinds, and aviation lease income — particularly if it is new, irregular, or flows through an entity — may be assessed at a significant discount, or excluded entirely by more conservative lenders.
Treating a trust structure as automatic protection
The idea that a trust structure automatically provides better borrowing-capacity protection than personal ownership is not reliable. The protection a trust offers depends heavily on how it is used, who controls it, and what guarantees have been given. Those variables matter more than the entity type.
When to speak to a broker, an accountant, and a lawyer
These three advisers serve different but connected functions, and the sequencing of when you engage them matters. When all three are communicating with each other before any structure is finalised, the outcomes are almost always better than when each adviser works in isolation. The right role for each is:
Mortgage broker
A mortgage broker should be your first call, not your last. A broker can model the serviceability impact of different ownership structures, identify which lenders are most likely to assess your situation favourably, and flag potential issues before any commitments are made. Engaging a broker after you have already signed an aircraft finance contract in a particular structure limits your options considerably.
Accountant
An accountant is essential for understanding the tax implications of different ownership structures, including depreciation, Goods and Services Tax (GST), Division 7A implications for company-owned assets, and how expenses flow through to your personal tax position. An accountant can also help you understand how different income structures will be viewed by lenders from a documentation and verification perspective.
Aviation lawyer or commercial solicitor
An aviation lawyer or commercial solicitor is the right person to advise on entity structures, registration, liability management, and the legal consequences of different ownership arrangements. They are not the right person to tell you how a bank's credit team will assess a personal guarantee — that is your broker's job.
The Bottom Line
Aircraft ownership does not automatically damage your borrowing capacity. But it can, and for many borrowers it does — often in ways that were not anticipated when the purchase was structured.
The critical insight is this: the question is not just how to finance the aircraft, but how the aircraft acquisition fits within your broader financial and property strategy. The structure you choose, the timing of the purchase, the guarantees you give, and the costs you carry all have consequences that a future lender will assess. Getting those elements right requires advice from people who understand both the aviation side and the mortgage lending side of the equation.
If you have property goals in the next 2 years and you are seriously considering an aircraft purchase, speak to a mortgage broker before you commit to a structure. A well-timed conversation can prevent a significant and largely avoidable problem later.

Frequently Asked Questions (FAQs)
Will buying an aircraft reduce my home loan borrowing capacity?
It depends on how the aircraft is financed and how the debt is structured. A loan in your personal name will directly reduce assessed borrowing capacity. A loan through a company or trust may also affect your capacity if a personal guarantee is involved, or if lenders treat the related entity's debt as a contingent personal liability.
Is it better to buy an aircraft personally, through a company, or through a trust?
There is no universal answer. Each structure has different tax, asset protection, and lending implications. The right choice depends on your circumstances, your property goals, and how your specific income and debt position will be assessed by lenders. A mortgage broker, accountant, and lawyer should each contribute to that decision.
If the aircraft loan is in my company's name, will banks still count it against me?
Often yes, particularly if you have provided a personal guarantee. Lenders differ in how they treat related-entity liabilities, but most experienced credit assessors will look through company structures to identify whether a personal obligation exists.
Does giving a personal guarantee affect my serviceability?
It can. Some lenders will count the full value of a guaranteed facility as a personal liability. Others may take a more measured approach if the entity servicing the debt can demonstrate adequate income from its own operations. Lender policy varies, which is why lender selection matters.
Can charter or lease income offset the aircraft loan in a mortgage application?
Not always, and not in full. Lenders typically apply a discount to investment or lease income. Aviation-related income, particularly if it is new or flows through a complex entity structure, may be assessed conservatively or excluded by some lenders.
Will an aircraft purchase affect pre-approval for a home loan?
Yes, if the purchase occurs before or during the pre-approval process, or if the debt and associated costs are visible to the lender. Pre-approval assessments are based on your financial position at the time of application. A significant new liability between pre-approval and formal approval can also cause problems.
Can I refinance my home loan after buying an aircraft?
In most cases yes, but the aircraft commitment may affect how much equity you can release or what loan amount you qualify for, particularly if the aircraft loan is in your personal name or you have given a guarantee. Serviceability is re-assessed at refinance, so the aircraft position will be visible to the new lender.
Do lenders count aircraft maintenance, insurance, and hangar costs as ongoing commitments?
They may, depending on how they appear in your financial records. Under responsible lending obligations, lenders must make reasonable inquiries about your expenses. If these costs appear in bank statements or tax returns, a thorough assessment will take them into account, either explicitly as declared commitments or within the living expense assessment.
Is a business-purpose aircraft loan treated differently from a consumer loan in Australia?
The loan itself may be structured differently and fall outside the National Credit Code if it is a genuine business-purpose facility. However, a personal guarantee on a commercial loan is still a personal obligation. The purpose classification of the loan does not eliminate the personal liability created by a guarantee.
Will using cash for the aircraft affect my property deposit position?
Potentially yes. Using a large portion of your liquid savings to purchase or co-fund an aircraft may leave you with a smaller deposit for a future property purchase, resulting in a higher LVR. A higher LVR may attract LMI, reduce your lender options, or require you to borrow more to achieve the same property outcome. This indirect effect is worth modelling before committing cash to an aviation purchase.
What is the safest structure if I want to buy property in the next 6–24 months?
There is no single answer, but the general principle is to minimise visible personal debt and guarantee exposure in the period leading up to your property application. Speak to a mortgage broker before choosing a structure, so that the lending implications are factored in from the start rather than discovered after the fact.
Should I get broker advice before signing an aircraft finance contract?
Yes, particularly if you have property lending goals in the foreseeable future. A broker can model how different structures affect your serviceability, identify which lenders are likely to assess your position most favourably, and ensure that the aircraft acquisition does not create unintended problems for your broader financial strategy.
