How Business Debt Affects Borrowing in Wollongong, NSW, What Lenders Actually Check

If you're running a business in Wollongong and thinking about buying property, you've probably wondered whether your business debt is going to be a problem. It's a fair question, and the answer depends entirely on how lenders see it, not how it feels on your end.

Most business owners assume their personal and business finances are neatly separate in a lender's eyes. Sometimes they are. Often they're not. Whether you're a sole trader, a company director, or a partner in a business, lenders look at the full picture of what you owe and what you earn before they'll commit to a home loan.

Our team helps business owners across Wollongong, NSW work through exactly this, comparing across 60+ lenders. The home loan side of it for business owners is where lender policy varies most, and where getting in front of the right lender makes the biggest difference.

Does business debt automatically reduce how much you can borrow?

Business debt reduces your borrowing capacity only when you're personally liable for it. A business loan secured solely against company assets, with no personal guarantee, often stays off your personal serviceability assessment entirely. What matters is the legal exposure, not the dollar amount on a business bank statement.

Where a personal guarantee exists, the repayment on that facility is counted as an ongoing commitment, the same way a car loan or a credit card limit would be. Lenders don't average it or discount it. That monthly repayment comes straight out of the income available to service a home loan.

How do lenders read business income alongside business debt?

Business income isn't read the same way as a salary. Lenders work from your tax returns, not from what lands in your business account, and the figure they care about is taxable income after allowable deductions, not gross revenue.

Two years of tax returns is the standard. Some lenders accept one year where the business is well-established and the income trend is clear, though that depends on the lender and the structure of your business. The two-year average is the safe assumption to plan around.

Add-backs: what gets counted back in

Certain deductions that reduced your taxable income on paper can be added back by the lender when working out your real cash position. Depreciation is the most common. One-off or non-recurring expenses are another. Which add-backs a lender accepts, and how they're evidenced, varies between lenders on the panel, which is one of the places where lender selection genuinely changes your number.

How business debt repayments interact with income assessment

If the business debt is personally guaranteed, its repayment is deducted from assessed income before the home loan serviceability test runs. This happens even if the business is generating enough cash to service that debt comfortably. The lender isn't looking at the business's cash flow; they're looking at your personal position.

APRA requires lenders to test serviceability at the actual rate plus a 3.0% buffer. That assessment rate applies to the home loan being applied for. The business loan's rate isn't buffered the same way, but its existing repayment is still counted as a commitment in full.

What eligibility conditions apply to business owners applying for a home loan?

Lenders don't have a separate eligibility category for business owners, but they do apply stricter evidence requirements. Here's what they typically verify:

What lenders want to see:

• › Two years of personal tax returns: with Notices of Assessment from the ATO confirming the figures lodged.
• › Two years of business tax returns: for companies, trusts and partnerships, showing the structure and profit trajectory.
• › Business financials: profit and loss statements and balance sheets for the last two financial years, prepared by an accountant.
• › Business loan documents: the facility agreement and any personal guarantee paperwork for existing business debts.
• › BAS statements: recent business activity statements, often for the last four quarters, to cross-check revenue trends.
• › ABN registration duration: most lenders want your ABN to have been active for at least two years, though some assess established businesses on shorter histories.

How much can a business owner borrow in Wollongong, NSW?

What you can borrow depends on three things working together: how much income the lender will accept, how much the existing business debt costs you in monthly repayments, and what living expenses the lender applies. Lenders use the Household Expenditure Measure as a floor for living costs, so declaring low expenses doesn't help if it's below their benchmark.

The APRA debt-to-income cap adds a further constraint. Since February 2026, lenders can write no more than 20% of new lending at a debt-to-income ratio of six times gross income or higher. For a business owner with significant existing business debt, this cap can bite before the serviceability calculation does, because total debt includes business liabilities you're personally responsible for.

In Wollongong, CoreLogic data shows house medians ranging from around $670,000 in Cringila through to $1,300,000 in Wollongong itself, with growth across most of the market over the past twelve months. How much of that range is reachable for a business owner depends on how cleanly the income and debt picture comes together. Unanderra at $880,000 and Dapto at $830,500 sit in the range where a well-documented business income, even with some business debt, can support a purchase without stretching to the edge of capacity.

What government schemes can business owners use in Wollongong?

Government schemes aren't closed to business owners, but they do carry conditions that interact with business income and debt in specific ways.

The main options worth knowing:

• › First Home Guarantee: 5% deposit, no LMI, no income cap. Price cap in the Illawarra is $1,500,000. Available to business owners buying their first home, assessed on the same income and serviceability basis as any other borrower.
• › NSW First Home Owner Grant:$10,000 for new homes only, up to a $600,000 purchase price ($750,000 for land-plus-build). Income and business structure don't affect eligibility, but the new-build requirement does.
• › Help to Buy: the federal shared-equity scheme, with income caps of $100,000 for singles and $160,000 for joint applicants. Business income is assessed on the prior year's ATO Notice of Assessment, so a strong year counts; a weak one doesn't help.
• › NSW transfer duty concession: full exemption on established and new homes up to $800,000 for first home buyers, with a concession band to $1,000,000. Applies regardless of employment type, subject to residency conditions tightened from August 2026.

How does a mortgage broker improve outcomes for business owners?

The lender choice decides the outcome here more than almost any other borrower type. Three policy differences move the number for business owners, and they're not published anywhere side by side.

• › Add-back treatment: some lenders accept depreciation, one-off losses and non-cash expenses as add-backs, lifting the assessed income figure materially. Others take the taxable income line as given and don't move from it.
• › Business debt liability: where a guarantee is worded as limited rather than unlimited, some lenders will assess the liability at the guarantee cap rather than the full facility balance. Others count the full balance regardless.
• › Trust income: if your business income flows through a trust, some lenders accept the full distribution as income where you're a beneficiary. Others exclude retained profits or apply a discount. The lender that suits a sole trader is often the wrong lender for a trustee.

Comparing across the panel before applying is what finds the lender whose policy fits your actual structure, rather than the one whose marketing is the loudest.

When does carrying business debt make a home loan harder to justify?

There are situations where the honest answer is that waiting improves the outcome significantly. If your business debt is in a growth phase, with repayments high relative to your current taxable income, a lender looking at the last two years may see a serviceability gap even if the business is genuinely profitable.

Similarly, if your business took a loss year recently, the two-year average pulls the assessed income down even if the current year is strong. In that situation, timing the application for after the second strong return is lodged is usually worth more than finding a marginally better lender today.

If your business and personal borrowings together would push your total debt above six times your gross income, the APRA DTI cap means some lenders will decline regardless of serviceability in isolation. Non-bank lenders are not subject to the same cap, which opens a different part of the panel, though their pricing reflects that.

What approval challenges do business owners face?

The most common hurdles:

• › Variable income across years: a dip in one of the two assessment years drags the average down, even when the current year is trading well. Lenders take the average; they don't take the most recent year on its own.
• › Open-ended personal guarantees: where the guarantee has no stated cap, the lender often counts the full facility balance as a personal liability, which can reduce borrowing capacity more than the actual monthly repayment would suggest.
• › Overlapping applications: if you apply for a business facility and a home loan within a short period, the credit enquiries stack up and the liabilities interact. Sequencing matters, and getting the order wrong can affect both applications.
• › ATO payment plans: an active ATO payment plan for a business tax debt appears on bank statements and is treated as an ongoing commitment by most lenders, reducing assessed capacity even after the debt is arranged.
• › Trust and company structures: more complex structures require more documentation and take longer to assess. A lender who doesn't regularly write for trust borrowers may decline on complexity alone rather than on the merits of the application.

Frequently Asked Questions

Does a business loan I've personally guaranteed count against my home loan borrowing capacity?

Yes, a personally guaranteed business loan is counted as a personal liability. The monthly repayment on that facility is deducted from the income available to service a home loan, regardless of whether the business is covering that repayment comfortably.

What if my business is in a company and I haven't signed a personal guarantee?

If there's no personal guarantee and the debt is secured solely against company assets, most lenders won't include it in your personal serviceability assessment. You'll need to provide the facility documents to confirm that position.

Can business owners access the First Home Guarantee in Wollongong, NSW?

Yes, self-employed and business-owner applicants are eligible for the First Home Guarantee. The Illawarra price cap is $1,500,000, and there's no income test. Income is assessed on the lender's standard two-year business income basis.

How do lenders treat a trust distribution as income for a home loan?

Treatment varies. Some lenders accept the full distribution as assessable income where you're a beneficiary; others discount retained profits or require the trust to have been operating for at least two financial years. Lender selection matters significantly here.

Is it better to pay down business debt before applying for a home loan?

Sometimes, but not always. If paying down the business debt uses cash you'd otherwise put toward a deposit, the trade-off may not be worth it. Whether it's better to reduce the liability or preserve the deposit depends on which constraint is binding in your specific position.

Should I use a mortgage broker or go directly to my business bank for a home loan?

A mortgage broker, every time. Your business bank sees your transaction history but only its own products. A broker compares across a panel of 60+ lenders and can find the one whose policy on add-backs, guarantees and trust income best fits your structure.
