Frequently Asked Questions
How much deposit do I need for a home loan in Australia?
A 20% deposit lets you avoid lenders mortgage insurance (LMI), but you can buy with less. With the First Home Guarantee, eligible first home buyers can buy with a 5% deposit and no LMI. Outside the scheme, many lenders accept 10% (with LMI), and some accept 5% with LMI or a guarantor.
What is lenders mortgage insurance (LMI)?
LMI is insurance that protects the lender (not you) when you borrow more than 80% of the property value. It is usually a one-off premium added to your loan. A guarantor or a larger deposit can help you avoid it.
What is a comparison rate?
A comparison rate combines the interest rate and most fees into a single percentage, so you can compare loans more accurately. It reflects the true cost of a loan, not just the headline rate.
What is the difference between fixed and variable rates?
A fixed rate stays the same for a set period (commonly 1–5 years), giving repayment certainty. A variable rate can move up or down with the market, and usually offers features like offset and redraw. Split loans combine both.
What is an offset account?
An offset account is a transaction account linked to your home loan. The balance offsets your loan balance for interest calculations, reducing the interest you pay — effectively earning a tax-free return at your loan rate.
How is borrowing capacity calculated?
Lenders calculate borrowing capacity from your income minus your expenses and debts, applying an assessment rate (a buffer above the actual rate) and a household expenditure measure. Different lenders use different methods, so your capacity can vary between lenders.
What is pre-approval and how long does it last?
Pre-approval (conditional approval) is a lender's written indication of how much you can borrow, subject to property valuation and final checks. It usually lasts 90 days. WRA arranges indicative pre-approval within 24–48 hours.
Should I use a mortgage broker or go straight to a bank?
A mortgage broker gives you access to many lenders at once and finds a policy fit for your situation, whereas a single bank can only offer its own products. For straightforward loans a bank may suffice, but for self-employed, complex or specialist scenarios a broker is usually the better path. With WRA, broker service is free to you.
