What is LMI (Lenders Mortgage Insurance) in Australia?

LMI protects the lender if you default on your home loan. It applies when your deposit is below 20% of the property value (LVR over 80%). LMI costs typically range from 0.82% to 3.4% of the loan amount depending on your LVR, and can be added to your loan or paid upfront. Use our LVR and LMI calculator in the Rate Sensitivity tab to estimate your LMI cost.

How much can I borrow for a home loan in Australia?

Borrowing capacity in Australia depends on your gross income, living expenses, existing debts and the lender assessment rate (typically your rate plus the 3% APRA serviceability buffer). Most lenders allow up to 38% of gross monthly income for total housing commitments. Use the Borrowing Power calculator in the Rate Sensitivity tab for an estimate based on your income and expenses.

Is it better to rent or buy in Australia?

Whether renting or buying is better depends on your specific numbers — property price, rent level, how long you stay, and what investment returns you could earn on your deposit. Our Rent vs Buy calculator in the Rent vs Buy tab models the year-by-year comparison including property growth, rental costs, mortgage repayments and investment returns.

What is a comparison rate on an Australian home loan?

A comparison rate is the true annual cost of a loan, combining the interest rate with most fees into a single percentage. Australian lenders are legally required under the National Credit Code to display comparison rates alongside advertised rates, calculated on a standard $150,000 loan over 25 years. Use our Comparison Rate calculator in the More Tools tab for your specific loan amount and fee structure.

How do I calculate rental yield on an investment property in Australia?

Gross rental yield is annual rent divided by property value, expressed as a percentage. For example, a property worth $750,000 renting for $600 per week has a gross yield of ($600 x 52) / $750,000 = 4.16%. Net yield subtracts ongoing costs (property management, council rates, insurance, maintenance). Use the Investment tab for a full yield, cash flow and ROI analysis.

How can I pay off my mortgage faster in Australia?

The most effective strategies are: making extra repayments (even $200/month extra can save years), using an offset account to reduce daily interest, switching to fortnightly payments (equivalent to one extra monthly payment per year), and making lump sum payments from bonuses or tax refunds. Use the Extra Repayments tab to combine all strategies and see your exact payoff date and interest savings.

What is negative gearing in Australia?

Negative gearing occurs when the costs of owning an investment property (including mortgage interest, management fees, rates and repairs) exceed the rental income. The resulting loss can be offset against other taxable income, reducing tax. Use the Investment tab to see whether your property will be positively or negatively geared based on your rental income and expenses.
