This is a cash-flow illustration, not a borrowing-power assessment or rent-versus-buy recommendation. A lender will assess income, expenses, debts, deposit, property, and its own criteria. A property’s value may rise or fall, while rent, rates, insurance, and maintenance can change.
Dave thought $800 was $800
Dave had been paying $800 in rent and managing. When he saw that the mortgage payment looked like $800, he thought buying would be a straightforward swap: stop paying the landlord and start paying off his own home.
He was wrong about what the swap involved. The mortgage was only the first bill. The house came with rates, insurance, repairs, maintenance, and a steady stream of costs he had never had to organise as a renter.
Two $800 mortgage examples
These are rounded planning amounts to show the shape of the budget. They are not quotes, and the actual costs depend on the property. Apartment body-corporate fees can include the building’s insurance and shared maintenance, so check what the levy covers before adding costs twice.
$800 mortgage payment
- Mortgage
- $800/week
- Rates
- $81/week
- House insurance
- $50/week
- Maintenance reserve
- $100/week
Owner housing budget: about $1,031/week$800 mortgage + $231 other ownership costs
$800 mortgage payment
- Mortgage
- $800/week
- Rates
- $60/week
- Contents and owner insurance
- $25/week
- Internal maintenance reserve
- $25/week
- Body-corporate levy
- $175/week
Owner housing budget: about $1,085/week$800 mortgage + $285 other ownership costs
So $800 rent is not automatically comparable with an $800 mortgage. The house example is about $231 a week higher before one-off buying costs. The apartment example is about $285 a week higher because body corporate sits on top of the mortgage.
Two couples, two very different outcomes
Dave and Diane. Their rent is $800 a week. They buy a house and the mortgage is $800 a week. They also save $300 a week on top of their rent before they buy.
That $300 is their breathing room. It covers the rates, insurance, maintenance and other costs that arrive with the house. Dave and Diane still go camping, still play badminton, and still have money left when something needs fixing. They do not have to pretend the mortgage is the whole cost because they have already practised living with less money.
Sophie and Mark. Their rent is also $800 a week. They buy a house and the mortgage is also $800 a week. But they have no savings left each week before they buy.
When the rates, insurance, maintenance and other bills arrive, there is nowhere for the money to come from. They stop camping. They stop spending on the things they enjoy. A car repair becomes a crisis. A household purchase goes on credit. They start looking at which car they can sell and which payments they can delay.
The mortgage did not become unaffordable because the payment changed. It became unaffordable because the couple had no room left after making it.
That is the whole lesson: Dave and Diane’s $300 weekly saving was already part of their home budget. Sophie and Mark treated the $800 mortgage as if it replaced the $800 rent, but they had no buffer for everything that ownership adds. One couple buys a home and keeps living. The other buys a home and starts cutting their life down to fit it.
What the simple comparison leaves out
- Deposit and the cash buffer they need after settlement.
- Lawyer, valuation, inspection, LIM, moving, and other one-off buying costs.
- Property-price changes and the equity created by principal repayments.
- Unconsented work, urgent repairs, and renovation decisions.
- Rent changes, moving costs, and the flexibility that renting can provide.
- Different loan structures, fees, refixing, and lender-specific stress tests.
The question Dave should have asked
Not “Can we make the $800 mortgage payment?” The useful question was: “After rates, insurance, maintenance, buying costs, and a proper buffer, can we still afford the life we want to live?”
