Mining town home loans: what lenders look at when you buy there

When a lender approves a home loan, it looks at two things: whether you can afford the repayments, and what the home would sell for if the loan went wrong. In a town built around one mine or one industry, the second question is harder to answer. Home prices there can rise fast when the mine is hiring and fall just as fast when it slows down or closes.

So lenders protect themselves on the property rather than on you. A strong income doesn't change the limit a lender sets for a postcode. These limits also move over time, tightening when a commodity price falls and easing when it recovers, so what a lender allowed a year ago may not be what it allows now.

Expect to need a much bigger deposit than you would in a city. As a general rule, most lenders will only lend about 70% of a mining-town home's value without lenders mortgage insurance (LMI, which covers the lender, not you, if a loan with a small deposit goes wrong). Some lenders will go to 80% or 90% of the value with LMI, but limit the loan to around $500,000. A few lenders don't lend in those postcodes at all.

To put the 70% figure in context: on a $450,000 home, a loan of 70% is $315,000, so you'd bring $135,000 yourself, before stamp duty (the state or territory tax on buying a property) and other buying costs. The loan's 70% share of the value is your LVR (loan-to-value ratio), and in a mining town it is often the number that decides the loan.

The lender also orders its own valuation of the home. If the valuer puts the home below the price you agreed to pay, the lender works from the lower figure, and you cover the difference.

Good news first: the Australian Government 5% Deposit Scheme does reach mining towns. Since 1 October 2025 it has had no income caps and no LMI, and its price caps are set by location. Mining towns are usually in the “other areas” band: a home in Moranbah (postcode 4744) is capped at $700,000 and a home in Karratha (6714) at $600,000. Both the price and the lender's valuation must stay at or below the cap.

Here is the catch. The scheme replaces LMI with a government guarantee, so the insurer is out of the picture, but the lender's own rules about the property are not. Lenders in the scheme still apply their own postcode limits, and it is up to each lender whether it accepts a mining-town home as security (the property the loan is secured against). So a 5% deposit in Moranbah needs a lender that is in the scheme and also accepts that postcode at 95% of the value, which can be hard to find.

If you tick the Australian Government 5% Deposit Scheme in our home loan comparison tool, lenders that aren't part of the scheme are greyed out with a reason. The tool can't tell you which of the rest accept your postcode, so that is a question for a broker.

In the Pilbara, three kinds of help each have their own limit, and they point in different directions:

• The WA First Home Owner Grant of $10,000, for a new home, reaches further in the north: the home can be worth up to $1 million north of the 26th parallel, which includes the Pilbara, against $800,000 south of it.
• Keystart, the WA Government's low-deposit lender, caps the price at $860,000 everywhere in WA, but lets a single buyer earn up to $225,000 in the Pilbara or Kimberley, against $155,000 in Perth and regional WA.
• The 5% Deposit Scheme reaches less far there: $600,000 in Karratha, as in the rest of WA outside Perth.

On top of all three sit the town limits mainstream lenders apply, which can bite hardest of all. Which help suits you depends on the home, your income and the lender, so it's worth checking the whole picture before you sign a contract.

Our tool runs your details through each lender's own servicing calculator (the sums a lender uses to test whether you can afford the repayments). It doesn't check mining-town postcode limits, so the figures it shows are what your income could support, not what a lender would lend on a home in a mining town. Your postcode can change the minimum living-expense figure some lenders use, but it doesn't bring in any mining-town limit.

That's why a broker matters here. A Xandii broker can tell you which lenders accept the postcode you're looking at, at what share of the value, before you commit to a home. If you work at the mine or on a fly-in fly-out roster, our guide to home loans for FIFO workers covers how lenders read roster pay, overtime and allowances.

What moved the figure

• The address and postcode of the home, before you sign, so a broker can check lenders.
• Proof of your deposit and where it came from, such as savings statements.
• A plan for a lower valuation: money set aside, or a contract that is subject to finance.
• Your two most recent payslips and your latest income statement or tax return.
• If you plan to use the 5% Deposit Scheme, proof that you are a first home buyer (or haven't owned property in Australia in the last 10 years) and that you will live in the home.
