How Business Debt Affects Borrowing in South West Sydney, NSW, What Lenders Check

If you're running a business in South West Sydney and wondering whether your company's debt is going to cost you a home loan, the answer is more nuanced than a flat yes or no. Lenders don't treat business debt the way they treat a car loan or a credit card, and the structure of how you owe it matters as much as the amount itself.

The good news is that many business owners in the Canterbury-Bankstown and Liverpool council areas are buying homes and investment properties with significant business debt behind them. What decides the outcome is how the debt sits, how it's evidenced, and which lenders your broker approaches first. Lenders across the panel read the same situation very differently, and that gap is where the work happens.

Our team helps business owners and company directors across South West Sydney, NSW understand how their financial position looks through a lender's eyes, comparing across 40+ lenders. The home loan side of it for business owners is where most of the difference is made.

Does business debt stop you getting a home loan in South West Sydney, NSW?

Not automatically, but it does change the assessment. Business debt held in a company structure is often treated separately from your personal liability, especially where you haven't provided a personal guarantee. The question lenders are actually asking is whether you are personally on the hook for the repayment, and if so, at what level.

How do lenders assess business debt on a home loan application?

Lenders look at whether the business debt creates a personal liability for you as the applicant. A term loan in a company name, without a director guarantee, generally doesn't appear as a commitment on your personal serviceability assessment. A loan you've personally guaranteed is a different matter entirely, because the lender treats the guaranteed amount as a contingent liability against your income.

The type of business debt also shapes the read. Equipment finance and chattel mortgages are asset-backed and typically assessed differently to an unsecured business line of credit. An ATO payment plan, even for a business tax debt, is increasingly visible to lenders and is read as an ongoing commitment in many cases.

What lenders look at in practice:

• › Personal guarantees: if you've signed one, the guaranteed debt is counted as a potential personal commitment, often at a portion of the total exposure.
• › ATO payment plans: treated as an ongoing monthly commitment by most lenders, reducing serviceability the same way a personal loan repayment would.
• › Business lines of credit: some lenders treat the full limit as a commitment regardless of the drawn balance, similar to how credit card limits are assessed.
• › Company-only debt: where no personal guarantee exists and the company is profitable, many lenders set this aside from the personal assessment entirely.
• › Cross-collateralisation: if business assets are already secured against a lender you're approaching for a home loan, the structure becomes more complex and a specialist assessment is usually needed.

What does business ownership actually do to your borrowing capacity?

The impact runs in two directions. On the liability side, guaranteed debt, ATO arrangements and business credit lines all reduce what lenders will lend you personally. On the income side, being self-employed or a company director means your income is assessed from tax returns and financial statements rather than payslips, which introduces its own constraints.

Most lenders want two years of tax returns for self-employed applicants, and they assess income on what the ATO sees, not what the business turns over. Add-backs, where a broker can include depreciation and certain one-off expenses back into the income figure, vary significantly between lenders. The difference between a lender that adds back depreciation and one that doesn't can easily change the assessed income by tens of thousands of dollars.

The APRA debt-to-income cap, effective from 1 February 2026, means lenders cannot write more than 20% of new loans at a debt-to-income ratio of six times gross income or higher. Business debt that creates a personal liability counts toward that ratio, so a director carrying a large guaranteed company loan alongside a home loan application is more likely to be affected by the cap than a salaried borrower with the same income.

What should business owners in South West Sydney do to prepare?

Preparation here is mostly about getting the paperwork in the right shape before you approach a lender. That means two years of tax returns and notices of assessment, up-to-date business financials, and clear documentation of which debts you've personally guaranteed and which sit in the company only.

An ATO payment plan that's current and being met is less damaging than one that's in arrears, but it should be disclosed and explained proactively rather than left for the lender to discover during verification. If your accountant has structured the business in a way that minimises assessable income for tax purposes, it's worth having a conversation with them before applying, because what works for tax minimisation often works against you in a serviceability assessment.

What to get in order before applying:

• › Two years of tax returns: personal and business, with notices of assessment to match.
• › Current financials: profit and loss and balance sheet, ideally prepared by your accountant and no more than 12 months old.
• › A list of all guarantees: which loans you've signed on personally, and the current balance of each.
• › ATO position: confirmation that all returns are lodged, and documentation of any payment plan currently in place.
• › BAS statements: the last four quarters, as a secondary income verification and to evidence trading consistency.

When does business debt genuinely make borrowing harder?

The situations that create real difficulty are where the debt is large, personally guaranteed, and the business income needed to offset it hasn't been consistently declared for two full years. A director who has been drawing a modest salary to minimise tax, while the profit sits in the company, can find that lenders will only assess the declared salary rather than the underlying business performance.

A large ATO payment plan in arrears is the other scenario that causes the most problems. Lenders treat it as evidence of financial stress rather than simple administration, and some will decline an application outright on that basis, even if everything else in the file is strong.

If you're in this position, it's usually better to wait until the plan is at least six months in and being met consistently before applying. Pushing the application through early and taking a decline on your credit file makes the next attempt harder. That said, some specialist lenders on the panel take a different view and assess the broader picture rather than applying a blanket rule on payment plans, which is where lender selection matters most.

How do mortgage brokers help business owners borrow in South West Sydney, NSW?

The lender selection is the whole game here. Three policy differences move the outcome for business owners, and they aren't published side by side anywhere.

• › Add-back treatment: some lenders include depreciation and certain one-off expenses in the income calculation and others don't, which changes the assessed figure before any rate or term is considered.
• › Guarantee assessment: how much of a personally guaranteed company loan is counted as a contingent commitment varies materially between lenders, and the difference can change whether you're under or over the DTI cap.
• › ATO payment plan tolerance: most mainstream lenders treat any active payment plan as a red flag, while a smaller number of specialist lenders assess whether the plan is current and on track, and proceed on that basis.

Knowing which lenders on the panel take which position means the application goes to the right place the first time, rather than sitting on a credit file with a decline attached.

When does it not make sense to apply yet?

If your most recent tax return is more than 18 months old, most lenders will decline on that basis before they even look at the debt structure. Getting returns lodged and a notice of assessment in hand is almost always worth doing before approaching any lender.

If the business has had a significantly lower-income year in the most recent return due to a one-off event, it may also be worth waiting for the current year's figures to be available. Lenders average two years of income, so a single strong year following a weak one still drags the assessed figure down. In some cases, applying six months later with a better average income changes the borrowing number more than any other variable in the application.

What approval challenges do business owners with debt face?

Where borrowers lose ground:

• › Tax minimisation that cuts assessed income: structures that reduce the declared profit for tax purposes can make the business look less profitable to a lender than it actually is, and most lenders assess what's declared, not what's distributed.
• › Undisclosed guarantees discovered in verification: lenders do a company search during assessment and personal guarantees that weren't listed on the application create a credibility problem as well as a serviceability one.
• › Applying to the wrong lender first: a mainstream bank with a strict ATO-plan policy is the wrong first call for a director with an active arrangement. A decline sits on the credit file for five years and changes how the next lender reads the application.
• › Business and property purchases competing at the same time: a director trying to expand business premises and buy a family home in the same year is putting two capital draws against the same income base, and lenders assess that full combined exposure.

Frequently Asked Questions

Does a company loan affect my personal home loan application?

Not always. A company loan with no personal guarantee is generally assessed as the company's liability, not yours. If you've signed a personal guarantee, the guaranteed amount is counted as a contingent commitment and reduces your assessed borrowing capacity.

How do lenders treat an ATO payment plan on a home loan application?

Most mainstream lenders treat an active ATO payment plan as an ongoing monthly commitment, reducing serviceability. A plan that is current and being met consistently is viewed more favourably than one in arrears, and some specialist lenders assess the plan's status rather than treating it as an automatic negative.

Can I get a home loan if my business had a bad year recently?

Yes, though a weak recent year lowers the two-year income average lenders use. Where the most recent return is significantly lower, waiting until a stronger current year's figures are available can materially change the assessed income and the borrowing outcome.

What is a director guarantee and how much does it affect borrowing?

A director guarantee is a personal commitment to repay a company debt if the business can't. Lenders treat the guaranteed amount as a potential personal liability, though how much of it reduces your serviceability varies between lenders and is one of the main reasons lender selection matters here.

Is a broker or a bank better for a business owner with complex debt?

A mortgage broker, every time. Mainstream banks apply standard credit policy that often doesn't account for add-backs, guarantee structures or the nuances of business income. A broker compares lenders whose policies actually fit the profile before the application goes anywhere.

Does the APRA debt-to-income cap apply to business owners?

Yes, where business debt creates a personal liability it counts toward the DTI ratio. The cap limits how much new lending authorised deposit-taking institutions can write above six times gross income, and personally guaranteed debt moves business owners closer to that threshold.

Your Next Steps

Business debt doesn't have to close the door on a home loan, but it does mean the application needs to be structured correctly before it goes anywhere near a lender. Getting the income evidence, guarantee disclosures and ATO position in order beforehand is what separates a clean approval from a credit file with problems on it.

The right lender for a business owner with debt depends on your situation, and that's a conversation worth having. Talk to the Infinity Mortgage Brokers team or call 0426 955 190, and we'll compare your options across 40+ lenders.
