How much should I budget for home maintenance?

Build the number from your own home. List major systems, estimate remaining life, divide local replacement cost by remaining years, and add routine upkeep on top.

Percentage-of-value rules ignore the two things that matter most: the age of your equipment and local labour cost. A house with a new roof and a twenty-year-old furnace has a very different profile from the reverse.

Keep routine spending in monthly cash flow and replacement money in a separate reserve so it does not quietly get spent.

What to check first

  • Install dates for roof, HVAC, water heater and major appliances
  • Local replacement cost estimates, not national averages
  • Annual routine costs: filters, servicing, gutters, sealing
  • Whether an existing warranty or service plan covers any of it

When to call a professional

  • You need a condition assessment to estimate remaining roof or system life
