One Doc Home Loan for Business Owners: Investment Property
Can a business owner with one year of BAS use a One Doc home loan to buy an investment property? In most cases, yes — and because non-bank lenders sit outside APRA's DTI cap, your borrowing capacity may be significantly higher than what a major bank offers. This guide covers what to prepare before you apply.
Quick Answer
Business owners can use a One Doc home loan to purchase an investment property using BAS-declared income instead of tax returns. Non-bank lenders assess servicing outside APRA's DTI framework, which means your borrowing capacity is based on actual business revenue — not artificially constrained by macroprudential caps that apply to the major banks.
Can a Business Owner Use One Doc for an Investment Property?
Yes. A One Doc home loan works for investment property purchases the same way it works for owner-occupied — you provide your accountant's declaration of income based on BAS activity statements, and the lender assesses servicing from that declared figure. No tax returns. No financials. One document.
The difference with investment property is how lenders treat the rental income. Most non-bank lenders will shade expected rental yield by 20–30% when calculating your servicing — meaning they'll count roughly 70–80% of the projected rent as income. This is standard across the industry, not specific to One Doc. What makes One Doc different is the income verification method: your business earnings are declared by your accountant rather than evidenced by two years of tax returns, which is where most self-employed borrowers get stuck at the major banks.
If your business has been trading for at least 12 months with a registered ABN, you have consistent BAS lodgement history, and your accountant can certify your income, you meet the starting criteria. The rest comes down to the property, the LVR, and how the numbers stack up at assessment. See our eligibility overview for the full list of who One Doc suits and who should avoid it.
When One Doc for Investment Property Is a Stronger Fit — and When It Gets Tricky
Not every business owner buying an investment property needs One Doc. If you have two years of clean tax returns showing strong net income, a standard low doc or full doc application through an ADI will give you a lower rate. One Doc becomes the stronger option when your tax returns don't reflect your actual earning capacity — because you've reinvested heavily, changed structures, or simply haven't lodged yet.
Stronger Fit
- 12+ months of consistent BAS showing strong turnover
- Retained earnings reinvested into the business (tax returns understate income)
- LVR at or below 75% — lower deposit pressure from property equity or cash
- Clean credit file with no defaults in the last 12 months
- Investment property in a metro or major regional area with strong rental demand
- Existing home loan paid down — not cross-collateralising with the business
Gets Tricky
- ABN registered less than 12 months — most lenders require minimum 1 year trading
- BAS shows declining turnover across the last 4 quarters
- Active ATO debt above lender thresholds without a formal payment plan
- LVR above 80% — One Doc investment loans rarely exceed 75–80% LVR
- Rural or niche property with limited comparable rental data
- Multiple existing investment properties already leveraged at high LVR
The card-box above isn't exhaustive — every application has nuance. But if you sit mostly in the left column, the conversation with a broker is worth having. If you're in the right column, there may be a path, but it requires more groundwork first. Start with the multiple revenue streams guide if your business has more than one income source — that's a common pattern for business owners who outperform their tax returns.
How Retained Earnings and Rental Yield Support Servicing
The servicing calculation on a One Doc investment application has two income legs: your declared business income and the expected rental yield on the investment property. The lender adds these together (after shading) and measures them against your total debt obligations — including existing home loan repayments, any business finance commitments, and the new investment loan repayment.
Business income (via BAS): Your accountant declares an annual income figure derived from your BAS activity statements. Lenders typically accept the lower of your last two BAS quarters annualised or your most recent 12 months of BAS turnover, adjusted by a margin for business expenses. The retained earnings your business holds — profit that sits in the business account rather than being drawn as personal income — can support this figure because it demonstrates that revenue exceeds your declared drawings.
Rental income (shaded): The lender takes the property's estimated rental yield — usually sourced from a valuer's assessment or a rental appraisal from a licensed property manager — and applies a shade of 20–30%. On an investment property expected to return $600 per week, the lender may count $420–$480 per week for servicing purposes. This is consistent across the market and accounts for vacancy periods and maintenance.
If your retained earnings are strong but your personal drawings are low, that's not a problem under One Doc — your accountant certifies the business income, not your personal tax return. This is the structural advantage for business owners who reinvest. For a deeper look at how multiple income streams feed into the calculation, see our guide on One Doc with multiple revenue streams. Also review how cashflow facilities interact with home loan servicing — if you hold a line of credit or working capital facility, it affects your capacity.
Why Non-Bank Lenders Bypass the APRA DTI Cap
Since 1 February 2026, APRA has required authorised deposit-taking institutions (ADIs — the major banks, regional banks, credit unions) to limit new mortgage lending where the borrower's debt-to-income ratio sits at or above six times their income to no more than 20% of all new lending. APRA also maintains a 3 percentage point serviceability buffer that ADIs must apply when stress-testing repayments.
Non-bank lenders are not ADIs and are not subject to APRA's macroprudential framework. This means a non-bank One Doc lender can approve an investment loan for a business owner whose DTI ratio exceeds 6x — provided the lender's own credit policy and responsible lending obligations are satisfied. For business owners carrying existing property debt, vehicle finance, and equipment loans, this distinction can be the difference between an approval and a decline.
This isn't a loophole. Non-bank lenders operate under their own Australian Credit Licence (ACL) obligations and must comply with responsible lending conduct under the National Consumer Credit Protection Act. They apply their own serviceability buffers and stress tests. The difference is that they're not bound by APRA's macroprudential caps — which are designed to manage systemic risk across the banking sector, not to measure individual borrower capacity.
For a business owner with strong BAS income and an investment property at 70% LVR, the non-bank pathway via One Doc may deliver a significantly higher borrowing capacity than the same application submitted to a major bank — even though the underlying income and expenses are identical. Our guide on One Doc after the APRA DTI cap covers the mechanics in detail.
Your Pre-Application Checklist: Five Documents to Have Ready
Before you apply for a One Doc home loan on an investment property, have these five items ready. Missing even one will delay your application — and in a competitive property market, delays cost you the deal.
Pre-Application Prep Checklist
Once these five items are assembled, your broker can run a preliminary servicing model and identify which non-bank lenders fit your profile before lodging a formal application. Check your eligibility here — no credit check, no obligation, and your broker will tell you where you stand within 24 hours.
One Doc home loans work for investment property purchases by business owners who have at least 12 months of BAS history and an accountant willing to certify income. Non-bank lenders sit outside APRA's DTI framework, which means your borrowing capacity reflects your actual business revenue rather than a macroprudential cap designed for the banking system. The key preparation: get your accountant's declaration, your BAS lodgements, and a rental appraisal sorted before you start looking at properties — not after you've found one.
Key takeaway: Prepare the five documents before you find the property. In a competitive market, the borrower who's pre-assessed wins the deal.Frequently Asked Questions
Yes — 12 months of ABN history is the minimum threshold for most non-bank lenders offering One Doc home loans. Your accountant must be able to certify income from at least 4 consecutive quarters of lodged BAS activity statements. Some lenders require 24 months for investment property specifically, but the majority accept 12 months provided the BAS shows consistent or growing turnover and your LVR sits at or below 75%. See our 1-year ABN guide for the full eligibility picture.
Most non-bank One Doc lenders cap investment property loans at 75% LVR, with some offering up to 80% for strong profiles. At 70% LVR, you'll access better rates and faster approvals because the lender carries less risk. The 75% threshold is the sweet spot — it balances borrowing capacity against pricing. Above 80%, One Doc investment options narrow significantly and typically come with higher rates and lenders mortgage insurance (LMI) requirements. Your servicing capacity determines the maximum loan amount within that LVR band — not just the property value. A broker models both constraints before you apply.
No. APRA's debt-to-income cap — which limits ADIs to no more than 20% of new mortgage lending at a DTI ratio of 6x or above — applies only to authorised deposit-taking institutions (major banks, regional banks, credit unions). Non-bank lenders operate under their own Australian Credit Licence and are not subject to APRA's macroprudential settings. This means a non-bank One Doc lender can approve investment lending for a business owner whose total debt-to-income ratio exceeds 6x, provided the application satisfies the lender's own credit policy and responsible lending obligations. Read the full APRA DTI cap guide for how this works in practice.
Yes, in most cases. Non-bank One Doc lenders typically accept borrowers with an active ATO payment plan provided you've maintained consistent repayments for at least 6 months and the plan is formally documented (not just an informal arrangement). The lender includes the ATO payment plan repayment in your debt commitments when modelling servicing — so it reduces your borrowing capacity but doesn't disqualify you. What does disqualify: unpaid ATO debt without any payment arrangement in place. If you have outstanding tax debt, set up a formal payment plan through the ATO portal before applying. The Business Owners Finance Hub has guides covering ATO debt and finance eligibility across all product types.
The lender takes the property's estimated weekly rental income — sourced from either a written rental appraisal by a licensed property manager or the valuer's assessment — and applies a shade of 20–30%. This means only 70–80% of the expected rent counts toward your servicing calculation. The shade accounts for vacancy periods, property management fees, and maintenance costs. This treatment is standard across the market, not specific to One Doc or low doc home loans. The stronger your BAS-declared business income, the less reliant you are on rental yield to support the application — which gives you more flexibility on property type and location.
