Plain-English answer

How much more does a low doc loan cost?

The direct answer
Low doc home loans typically carry an interest rate premium of 0.3-1.5% above equivalent full doc rates. On a $500,000 loan, a 1% premium means roughly $5,000 per year or $415 per month in additional interest. The exact premium depends on the lender, your LVR, the type of documentation provided, and whether the loan is owner-occupied or investment. BAS-verified applications generally attract lower premiums than bank statement only.

Breaking down the costs

The primary cost of a low doc loan is the interest rate premium. This is built into the ongoing rate and is not a separate fee. On a $400,000 loan, a 0.5% premium adds roughly $2,000 per year in additional interest. On a $700,000 loan, the same premium adds $3,500 per year.

At the higher end, a 1.5% premium on a $500,000 loan means roughly $7,500 per year or $625 per month more than a full doc borrower would pay. This is why choosing the right lender matters - the difference between a 0.3% and 1.5% premium on the same loan is substantial.

Beyond the rate premium, some lenders charge a low doc loading on lenders mortgage insurance (LMI) if applicable, though most low doc loans do not require LMI because the LVR is capped at 80%. Application fees may be slightly higher with some lenders, and valuation requirements may be stricter - some lenders require a full valuation rather than accepting an automated one.

There are no ongoing low doc fees beyond the rate premium itself. The premium is simply reflected in your interest rate, which means it compounds over the life of the loan. This is why refinancing to a full doc rate once you have tax returns is such an effective strategy.


Common questions

Frequently asked questions

Can I negotiate a lower low doc rate?
Your broker negotiates on your behalf. The rate depends on your LVR, documentation strength and the lender's appetite. Borrowers with strong BAS evidence and lower LVR (under 70%) typically get the most competitive low doc rates.
Is the low doc premium tax-deductible on investment loans?
Yes. The full interest amount including the low doc premium is generally deductible on investment loans. The premium is simply part of your borrowing cost. Speak with your accountant for specific advice.
How do I get rid of the low doc premium?
Refinance to a full doc loan once you have lodged 2 years of tax returns. This is the most effective way to eliminate the premium and can save thousands per year.
