Understanding Australian Mortgages

Australia's mortgage market operates heavily on variable rates, though 1- to 5-year fixed periods are common. Lenders Mortgage Insurance (LMI) is required if your deposit is under 20%, but unlike the US PMI, it is typically a single upfront premium capitalized into the loan. State governments heavily tax property purchases via Stamp Duty, which can significantly impact your upfront buying power.

Australia Mortgage FAQ

You need a deposit of at least 20% (LVR of 80% or below) to avoid LMI from standard lenders. Through the First Home Guarantee, eligible first home buyers can purchase with 5% deposit without paying LMI.
The Reserve Bank of Australia sets the cash rate, which directly influences variable home loans. A 0.25% rate rise on a $700,000 mortgage adds approximately $109/month to repayments.
An offset account is a transaction account linked to your mortgage. The balance is subtracted from your loan before interest is calculated. E.g. $600,000 loan with $50,000 offset — you only pay interest on $550,000.
The FHBG allows eligible first home buyers to purchase with 5% deposit without paying LMI. The government guarantees 15% of the loan value. Apply through a participating lender. Income caps: $125,000 singles, $200,000 couples.
