Small business home loan eligibility: what lenders want to see

Self-employed business owners absolutely can qualify for a home loan, but eligibility rules are tougher than for employees. Lenders want to see (1) stable, provable income for at least 1–2 years, (2) clean, lodged tax returns, (3) a deposit of at least 5–20%, (4) a clear credit file, and (5) evidence you can afford repayments at your actual interest rate plus at least 3% (the APRA serviceability buffer). This guide walks through what that means in practice and what you can fix this week.

1. What is a “small business home loan” in practice?

There’s no separate product called a “small business home loan” at most banks. You’re applying for a standard home loan, but you’re assessed as a self-employed borrower rather than a PAYG employee.

The key differences:

• Your income comes from your business profits and drawings, not a payslip.
• Lenders scrutinise your business financials and tax compliance.
• Any business debts with personal guarantees are treated as your personal commitments.
• Volatile income is stress-tested harder because of the APRA 3% buffer.

For you, eligibility boils down to two stories:

1. Personal story – your credit file, savings habits, living costs and existing debts.
2. Business story – how stable, profitable and resilient the business is.

If both stories hang together, you’re in a strong position, even if your income is lumpy from month to month.

Getting your business and personal numbers organised is the first step toward home loan eligibility.

2. Core eligibility checklist for small business owners

Think of eligibility as a checklist. If you can confidently tick most of these, you’re close to application‑ready.

2.1 Personal profile

1. Residency and age

• Australian citizen or permanent resident (most lenders).
• At least 18 years old.

2. Deposit and equity
Indicative bands (can vary by lender and policy):

• 20% deposit (80% LVR) – best pricing, often no LMI.
• 10–15% deposit (85–90% LVR) – LMI likely, stronger income story needed.
• 5% deposit (95% LVR) – usually only with government guarantees or very strong profiles; documentation must be tight.

3. Credit history

• On‑time repayments for last 12–24 months.
• Minimal unsecured debts (credit cards, Afterpay, personal loans).
• Any defaults or judgements explained and ideally paid.

2.2 Business profile

Most mainstream lenders look for:

• Time in business: 2 years with ABN and GST registration (where relevant) is the sweet spot. Some will consider 1 year if the story is strong.
• Consistent or growing profit: Declining profit over two years is a red flag unless clearly explained.
• Separate accounts: Running business income and expenses through separate business accounts for 3–6 months usually boosts lender confidence (see /insights/separating-business-personal-cashflow-mortgage referenced fact).
• No unmanaged ATO debt: A small, documented payment plan can be workable; large undisclosed tax debt is often a deal‑breaker.

2.3 Income and serviceability

Two big concepts drive eligibility:

1. Serviceability buffer (APRA rule) – Lenders must test if you can afford repayments at at least 3% above your actual rate. If your actual variable rate is 6%, they assess you at 9% or more.[^apra]
2. HEM (Household Expenditure Measure) – A benchmark of minimum living costs based on your family size and location. Lenders take the higher of your declared expenses and HEM.

Combined with volatile income, that buffer (3) means self-employed borrowing capacity can be much lower than you expect from your top‑line revenue.

3. How lenders assess self-employed income

Every lender has its own policy, but the backbone is similar.

3.1 Structures: sole trader, company, trust

How your income is calculated depends on how your business is set up:

• Sole trader: Lenders start with net profit from your personal tax return.
• Company: They look at your salary + dividends + share of retained profit you can reasonably access.
• Trust: They assess the distribution to you plus any salary you draw.

In all cases, most lenders:

• Want two years of lodged tax returns (personal and business).
• Calculate income using either:
  • the lower of the last year and 2‑year average, or
  • latest year only if it’s clearly higher and sustainable.

3.2 Tax returns, add-backs and deductions

Most lenders start from taxable profit and then add back certain items to reflect your real earning power:[^addbacks]

• Depreciation and amortisation – non‑cash expenses.
• One‑off or extraordinary costs – e.g. fit‑out, relocation.
• Some interest expenses – if those debts will be cleared or refinanced.

But there’s a catch:
Aggressively minimising taxable income can severely reduce your borrowing capacity, because lenders are not allowed to just accept your own “true income” estimate.

If you’ve been claiming heavily for a few years, it’s worth reading /insights/using-tax-returns-to-prove-income-home-loan before your next tax planning cycle.

3.3 Example: how assessable income is calculated

Say you run a company and your latest year shows:

• Your salary: $80,000
• Company taxable profit: $70,000
• Depreciation expense: $10,000
• One‑off legal fees (documented): $5,000

A lender might calculate your income roughly as:

• Salary $80,000
• Plus: profit $70,000
• Plus: add‑backs $15,000
• Total assessable income ≈ $165,000 p.a.

Another lender might be more conservative and use only salary + part of profit, especially if profit has been volatile.

3.4 APRA buffer, HEM and borrowing capacity

Let’s take a simple example.

• You want to borrow $800,000 over 30 years, principal & interest.
• Indicative actual rate: 6% p.a. (illustrative only).
• APRA buffer: assess at 9% p.a.

Approximate repayments:

• At 6%: about $4,800 per month.
• At 9%: about $6,450 per month.

The bank will only approve the loan if, after allowing for HEM living costs and your other debts, your documented income comfortably covers $6,450 per month, not just $4,800. That’s why small dips in profit or extra credit cards can suddenly kill a deal.

With mortgage stress already affecting over 28% of Australian mortgage holders according to Roy Morgan’s 2026 research, regulators and banks are in no mood to be generous with these tests.

Lenders test your borrowing capacity using interest rates at least 3% above today’s to meet APRA rules.
