Renting vs buying in Australia
Australian lending is shaped by the Australian Prudential Regulation Authority (APRA), which requires banks to assess your repayments with a serviceability buffer of 3.0% above the loan's rate, and by ASIC's responsible-lending obligations. If your deposit is under 20%, you'll usually pay Lenders Mortgage Insurance (LMI), which protects the lender, not you.
Variable-rate loans are common and move with the Reserve Bank of Australia's cash rate, though fixed periods are available. Terms run up to 30 years. On purchase you pay stamp duty set by your state or territory on a sliding scale, with concessions for many first-home buyers.
A worked example
On a $600,000 loan at 6.4% over 30 years, the monthly repayment is roughly $3,755. Because APRA adds a 3% buffer, the bank will test whether you could still afford repayments at around 9.4%, which is often what limits borrowing capacity rather than the current rate.
- Regulators: APRA and ASIC, with rates tracking the RBA cash rate.
- Key rule: 3.0% serviceability buffer on assessment.
- Extra costs: LMI under a 20% deposit, plus state stamp duty.
Australia-specific questions
What is the APRA serviceability buffer?
APRA requires lenders to check you could still afford repayments if your interest rate rose by 3 percentage points above the current product rate. It's a stress test that reduces how much most people can borrow.
When do I pay Lenders Mortgage Insurance?
Typically when your deposit is less than 20% of the property value. LMI protects the lender if you default; it's a cost to you and can be paid upfront or added to the loan.
Rent vs. Buy: The True Cost Comparison
Deciding whether to rent or buy is rarely as simple as "rent is throwing money away." Both options carry costs that never build equity, and the right choice depends on your time horizon, local prices, and what you would do with the money you don't tie up in a deposit. This guide lays out the full framework a good rent-vs-buy calculator uses.
The Costs That Don't Build Equity
Renting's obvious non-equity cost is rent itself. But buying has its own "phantom" costs that also build no equity: mortgage interest, property taxes, insurance, maintenance (often estimated at ~1% of the home value per year), and one-off transaction costs on the way in and out. A fair comparison pits rent against the sum of these ownership costs - not against the entire mortgage payment, part of which is forced savings.
The Break-Even Horizon
Because buying front-loads large transaction costs (stamp duty or transfer tax, legal fees, agent fees), it usually takes several years of ownership before buying pulls ahead of renting. This is the break-even point. If you expect to move before it, renting is often the financially stronger choice; stay well beyond it, and ownership typically wins as the mortgage amortizes and (historically) the property appreciates.
Opportunity Cost of the Deposit
A deposit is a large sum of capital. If you rent instead of buying, that capital could be invested. A rigorous comparison therefore models the "rent and invest the difference" scenario: the renter's net worth is their invested deposit plus any monthly savings, compounded at an assumed return, versus the buyer's home equity plus appreciation. The winner is simply whoever has the higher net worth at your planned sale date.
Frequently Asked Questions
Is renting really 'throwing money away'?
Not necessarily. Rent buys you flexibility and frees your capital to invest. Meanwhile a large share of an early mortgage payment goes to interest - money that also builds no equity. The honest comparison is total non-equity cost on each side, plus the opportunity cost of the deposit.
What is the break-even point?
It's the number of years you must own before buying becomes cheaper than renting, after accounting for transaction costs. Sell before it and you likely lose money versus renting; hold past it and ownership tends to win.
How much should I budget for maintenance?
A common rule of thumb is about 1% of the property's value per year, though older homes can cost more. Renters generally avoid these costs, which is a real and often overlooked advantage of renting.
Does home price appreciation guarantee buying wins?
No. Appreciation helps buyers, but it isn't guaranteed and varies widely by location and period. A robust decision holds up even under a modest-appreciation scenario rather than assuming prices always rise quickly.
