Ongoing Costs of Owning a Home Per Year

Published 31 May 2026

The short answer

Beyond your mortgage, owning a home in Australia typically costs roughly $6,000–$15,000+ per year in 2025-26. The main ongoing costs are council rates (about $1,500–$2,500), water and sewerage (about $1,000–$1,500), building or home-and-contents insurance (about $1,500–$4,000 depending on your state and risk), strata/body-corporate fees if you own an apartment or townhouse (often $2,000–$10,000+), and a maintenance buffer of roughly 1% of the property's value each year. Owner-occupiers are normally exempt from land tax on their main home.

How ongoing home costs work in Australia

"Ongoing costs" are everything you pay to keep a home, separate from the upfront costs (deposit, stamp duty, LMI, conveyancing) and separate from your loan repayments. They recur every year for as long as you own the property.

Worked example: a $750,000 house in NSW

Imagine a standalone house (no strata), valued at $750,000, lived in as your home:

CostEstimate (per year)
Council rates$2,000
Water & sewerage$1,200
Building + contents insurance$2,500
Maintenance (≈1% of $750k)$7,500
Land tax (owner-occupier)$0 (exempt)
Total ongoing$13,200

That's about $1,100 a month on top of your mortgage. For comparison, a standard $600,000 loan at 6% over 30 years repays about $3,597 a month, so the running costs add roughly a third again on top of the loan repayment.

Swap the house for a $750,000 apartment and you'd usually drop the standalone maintenance buffer but add strata fees of, say, $6,000/year, since building insurance is typically already inside the strata levy. The total often lands in a similar range, just split differently.

Model this in True Loan

True Loan has dedicated ongoing-cost inputs so your monthly picture includes more than the repayment. Open the calculator and:

  1. Set your loan amount, interest rate, term and repayment frequency to get the repayment.
  2. In the ongoing costs section, enter council rates, water, insurance, strata, maintenance, land tax and property management. Use the estimates above as a starting point, then refine with your own quotes.
  3. If you have savings sitting against the loan, use the dedicated Offset balance input; if you're paying down faster, use the separate Extra repayment ($/month) input. They're modelled independently.
  4. Want to weigh a house against an apartment (different strata vs maintenance mix)? Build both in True Loan Compare and view them side by side. Every scenario is shareable by URL.
