What is a low doc loan?

A low doc (low documentation) home loan is built for borrowers whose income is real but does not sit neatly inside the payslip-and-PAYG mould the banks are designed around. If you are self-employed, a business owner, a contractor, a seasonal worker or a freelancer, you may not have two years of tax returns or the continuous employment history a standard application asks for. Your income may be irregular in its timing, yet still high enough and stable enough to comfortably meet the repayments. The low doc loan exists to assess that income through a different lens.

This is a policy question, not a verdict on your income. Being self-employed does not automatically push you into low doc territory. If your business is older than two years, trades steadily, and you hold the full set of documents a standard loan requires, it is often possible to meet a lender's criteria for a full doc home loan at full doc pricing. The work is in knowing which path your actual circumstances fit before an application is lodged.

Since the 2009 Global Financial Crisis, changes to credit regulation — including the National Consumer Credit Protection Act 2009 — tightened the requirements considerably. Fewer borrowers qualified, and many lenders stopped offering low doc loans altogether. The lenders who remain each read low doc circumstances differently, which is why it matters to deal with someone who understands each lender's low doc and alt doc criteria. Lodging with the wrong lender and being declined leaves a trail of credit inquiries on your file, and several applications in a short window make the next lender more cautious again.

The documentation: low doc is really alt doc

Before 2009, a low doc loan meant exactly that — less documentation and less proof of savings. That changed. Lenders are still obliged to understand a borrower's circumstances and their genuine ability to meet repayments, so the modern product is more accurately described as alt doc (alternative documentation). The difference from a full doc loan is in the type of information required, not the volume of it. You are evidencing the same income; you are simply doing it through a different set of documents.

Alternative documents a lender may accept for a low doc or alt doc loan include:

No single lender asks for all of these, and the combination they will accept is itself a policy question. Part of structuring an alt doc application is choosing the lender whose evidence requirements match the documents you can actually produce.

Rates, fees and how LVR drives the cost

Because a lender is assessing your income through an alternative path, an alt doc loan can carry a higher interest rate than the equivalent full doc variable rate home loan — the rate reflects how the lender prices that assessment. The single biggest lever on that rate is your loan-to-value ratio (LVR): the more you borrow against the property's value, the higher the rate tends to be. The gap over a full doc variable rate can range indicatively from around 1% to 3% or more depending on the lender and the LVR, which is precisely why knowing the current market matters before you commit.

Where the structure allows it, the cost can come down sharply. If you can place a large enough deposit that you are borrowing under 60% of the property value (60% LVR), it may be possible to secure a rate at or close to the standard variable rate. LVR is the variable you can most directly influence.

Fees can also run higher than on a full doc loan, depending on the lender. In place of Lenders Mortgage Insurance (LMI), some lenders apply a risk fee when you borrow above 60% of the property value. These costs are part of the trade for access, and they belong in the comparison rather than as a surprise at settlement.

The features you keep

Choosing an alt doc loan does not mean giving up the mechanics of a normal home loan. The usual features generally remain available, including:

That matters structurally. An alt doc loan should be built so it can be refinanced cleanly to a full doc product once your business history and documentation line up — not locked into terms that trap you in the higher rate. The right move now is the one that leaves the door open later.

If you are self-employed and trying to work out whether low doc, alt doc or full doc is genuinely the right path — and which lender's policy fits the documents you can produce — it is worth mapping before anything is lodged.
