Help to Buy and your borrowing power

Last updated September 2026  ·  Back to the calculator

Help to Buy is the Australian Government's shared equity scheme. The government buys part of your home with you, so you need a smaller deposit and a smaller loan. That second part is what makes it different: it is the only first home buyer scheme that reduces the loan the lender tests against your income. (Deposit is not the problem? See the 5% Deposit Scheme instead, and the comparison below.)

What the scheme actually does

For example, on a $700,000 existing home with a $14,000 (2%) deposit, the government could put in up to $210,000 and your loan would be about $476,000. Without the scheme the same home would need a loan of $686,000.

Why it can lift what you can buy

Lenders work out the largest loan your income can support, using a test rate well above the real rate and the higher of your declared expenses or a benchmark. Help to Buy does not change that test. It changes the price that loan can buy: if the government owns 30%, a loan of $476,000 plus your deposit covers a $700,000 home. Your borrowing power stretches further, up to the price cap for your area.

Help to Buy or the 5% Deposit Scheme?

Both are for first home buyers and both avoid LMI. They solve different problems.

Best whenYour income supports the loan but your deposit is smallYour deposit is small and your income cannot support a full-size loan

You cannot use both on the same purchase, but Help to Buy can be combined with state first home owner grants and stamp duty concessions. Our calculator shows what each scheme could reach for you side by side when you say you are a first home buyer.

Before you make an offer

  1. Get an indicative estimate that includes both schemes (our calculator does this in about 60 seconds).
  2. Check your taxable income against the limit and the price cap for the property's postcode.
  3. Check state grants and stamp duty concessions, which can apply as well.
  4. Talk to a mortgage broker about which scheme suits you and which participating lender to use.

How a broker helps, at no cost to you

  • Finds the right lender. Compares lenders across their panel to find which will lend you the most, including those taking part in the 5% Deposit Scheme and Help to Buy.
  • Handles the scheme. Checks your eligibility and the price cap, and applies for your scheme place through the lender.
  • Gets you ready to bid. Sorts the paperwork and a pre-approval before you make an offer.

Who pays? Most mortgage brokers charge you nothing. The lender you choose pays the broker a commission when your loan settles. By law a broker must act in your best interests, not the lender's. We may receive a referral fee from the broker; it does not change what you pay.
