Investment Property Loans: How They Differ From Owner-Occupier Loans
I get a version of this question constantly from clients who already own their home and are looking at their first investment property. They assume
I sit down with a business owner almost every week who’s convinced they can’t get a home loan simply because they don’t have payslips. It’s one of the most common misconceptions I come across, and it stops good, capable buyers from even trying. So let’s clear it up properly. You absolutely can get approved without payslips. You just need to understand what lenders actually want in their place, and how to present your income so it reflects what your business genuinely earns.
Payslips exist because they’re an easy, standardised way for a lender to see exactly what someone earns each pay cycle. If you’re self employed, there’s no employer issuing that document, so lenders have built entirely separate assessment pathways to verify your income instead. According to ASIC’s Moneysmart, a low doc loan is specifically designed to require less financial documentation to prove income, assets, and liabilities than a standard loan, and it’s typically used by self employed people and small business owners for exactly this reason. This isn’t some obscure workaround. It’s a mainstream, well established part of how Australian lending works.
Full doc. This is the standard path, and if you can provide it, it’s almost always your best option. It typically means two years of personal and business tax returns, your most recent notices of assessment, and sometimes your two most recent Business Activity Statements. Lenders will average your income across the two years, or in some cases use the lower of the two, to work out what you can service. Full doc loans are priced the same as, or very close to, standard PAYG loans, because the lender has the same level of certainty about your income that they’d get from an employee.
Low doc, also called alt doc. This is where things get more interesting for a lot of business owners. If your tax returns don’t fully reflect your actual cash flow, which happens often once your accountant has claimed legitimate deductions, or if you simply don’t have two full years of tax returns finalised yet, a low doc loan lets you verify your income using alternative evidence instead. This typically means BAS statements, an accountant’s letter or declaration confirming your income, and recent business bank statements showing consistent trading income.
It’s worth being clear about something here, because I take it seriously with every client. Low doc doesn’t mean no doc, and it definitely doesn’t mean you can just declare whatever number gets you the loan you want. Whatever income you declare has to be genuine and supportable, and inflating it to qualify for a bigger loan isn’t just risky, it’s fraud, with real legal consequences attached. A good broker will make sure your application reflects your real numbers properly, not just the number you’d like a lender to see.
Regardless of which path you take, here’s the documentation I typically pull together for a self employed application.
An active ABN, generally registered for at least twelve to twenty four months depending on the lender, though some will consider you sooner if you have prior experience in the same industry.
Two years of tax returns and notices of assessment, if you’re going the full doc route, or your most recent one to two BAS statements if you’re going low doc.
Six to twelve months of business bank statements, showing consistent income landing in the account, which is often the single most convincing piece of evidence in a low doc application.
An accountant’s letter or declaration, confirming your income and business structure, particularly useful if your tax returns understate your actual trading position.
Evidence of GST registration, if applicable to your business.
Your existing debts and living expenses, the same as any other borrower, since serviceability is assessed on your whole financial picture, not just your income.
This is the part that frustrates business owners the most, and it’s worth understanding properly rather than just accepting it. Lenders assess your taxable income, which for a lot of self employed people is deliberately lower than what the business actually generates, because a good accountant has claimed every legitimate deduction available. Depreciation, one off equipment purchases, and certain business expenses can all reduce your taxable income on paper while your actual cash position stays strong.
Some lenders will add certain non cash expenses, like depreciation, back into your assessed income once they’ve been properly identified and documented. Not every lender applies this the same way, and this is exactly the kind of policy difference that makes comparing lenders properly worth the effort, rather than accepting the first assessment you’re given.
I won’t pretend low doc loans are priced identically to full doc loans, because they’re not. Rate loadings on alt doc products typically sit somewhere around half a percentage point to one and a half percentage points above a comparable full doc rate, and most mainstream lenders cap low doc lending at 80 percent loan to value ratio, meaning you’ll generally need at least a 20 percent deposit to avoid Lenders Mortgage Insurance. Some specialist lenders apply an even lower LVR ceiling before LMI kicks in on a low doc product, so this is worth checking carefully rather than assuming standard LMI thresholds apply across the board.
The premium isn’t usually dramatic, and for a lot of business owners, particularly those in the early years of trading or transitioning from employment into their own business, it’s a reasonable trade off for getting into the market now rather than waiting years to accumulate two full years of ideal tax returns.
It’s also worth understanding a shift that’s happened in the broader lending landscape recently. From February 2026, the Australian Prudential Regulation Authority introduced a rule limiting how much high debt to income lending Australian banks can write. According to APRA’s own announcement, authorised deposit taking institutions, meaning banks, credit unions, and building societies, must now limit new mortgage lending at a debt to income ratio of six times or more to no more than 20 percent of their total new lending, applied separately to owner occupier and investor portfolios. This restriction only applies to ADIs. Non bank lenders aren’t subject to this cap at all, which has made them an increasingly important part of the market for certain borrowers, including some self employed applicants whose overall debt position sits on the higher side. It doesn’t mean banks are closed to self employed borrowers, but it’s one more reason a broader comparison across both bank and non bank lenders is worth doing rather than only checking with your everyday bank.
Keep your business and personal finances properly separated. A business account that clearly shows trading income, separate from personal spending, makes your bank statements far easier for a lender to read and trust.
Get ahead of one off events. If you had an unusually low income year, a one off expense, or a temporary dip in revenue, have a clear explanation ready, ideally backed by your accountant, rather than leaving a lender to guess.
Avoid unnecessary credit applications in the lead up to your loan. Multiple credit enquiries close together can affect how a lender views your application, regardless of your income.
Build your trading history where you can. If you’re only a few months short of the twelve month mark most lenders prefer, it’s sometimes worth waiting rather than applying prematurely and receiving a weaker offer.
Talk to a broker before you talk to a bank. Not every lender treats self employed income the same way, and going in without comparing your options first can mean accepting a rate or a structure that isn’t actually your best available option.
FAQs
It's difficult through mainstream lenders, who generally prefer twelve to twenty four months of trading history, but some specialist lenders will consider a shorter history if you have relevant prior experience in the same industry and strong supporting bank statements.
It's not always mandatory, but having one is a genuine advantage. An accountant's letter confirming your income carries real weight with lenders, particularly on a low doc application.
No. No doc loans, which required almost no income verification at all, were largely phased out after the Global Financial Crisis and under current responsible lending rules. A low doc loan still requires genuine supporting evidence, just a different type than a standard payslip based application.
Usually not dramatically higher. Most low doc loans carry a modest rate loading over an equivalent full doc product, rather than a steep premium, though the exact gap varies by lender.
Yes, low doc lending is available for both owner occupied and investment purchases, though the exact deposit and documentation requirements can differ between the two.
It depends on the reason and how the rest of your financial position looks. A one off loss with a clear explanation, strong bank statements, and a solid deposit can often still be worked with, particularly through a low doc pathway.
If you’ve been told by a bank that your income doesn’t fit their box, that’s exactly the kind of situation I help business owners work through regularly.
