The Hidden Costs of Homeownership

The expenses every first-time buyer wishes they'd budgeted for — from the predictable (taxes, insurance) to the genuinely surprising.

6 min readUpdated October 2025

Comparing rent to a mortgage payment is the most common mistake first-time buyers make. The mortgage is only part of the picture.

The big recurring costs

  • Property tax (annual, can rise with revaluations).
  • Building insurance (required by most lenders).
  • Strata / HOA / service charges for apartments and managed estates.
  • Utilities — often higher than what you paid as a renter.

Maintenance: the 1% rule

A common rule of thumb is to budget around 1% of your home's value per year for maintenance and repairs. In some years you'll spend nothing; in others you'll replace a roof or a heating system in a single bill.

One-off surprises

  • Furniture, appliances, curtains and blinds for an empty home.
  • Special assessments from your strata or HOA for major works.
  • Local taxes triggered by renovations or extensions.
  • Higher insurance premiums after a claim, even one that wasn't your fault.

Tip

Build a 'house fund' separate from your emergency fund. The first time the boiler dies on a Sunday, you'll be glad you did.
