Rent vs Buy: How to Decide
“Renting is throwing money away” is one of the most expensive sentences in personal finance. Sometimes buying wins by a mile; sometimes renting wins by more. The answer depends on numbers, not slogans. Here is a framework for getting it right.
The 5% rule
Owning costs roughly 5% of the home’s value per year in unrecoverable costs: ~3% for the mortgage interest (the part of your payment that is not building equity), ~1% for property tax, ~1% for maintenance. Compare that yearly figure to the annual rent of a similar place.
If a similar place rents for $1,400/month → renting is likely cheaper.
If it rents for $2,000/month → buying likely wins.
It is a rule of thumb, not a verdict — but it reframes the question correctly: compare unrecoverable costs, not mortgage vs rent.
The breakeven horizon
Buying has huge upfront costs (down payment, closing costs, moving) that renting does not. Those get amortized over time, so buying usually needs 5–7 years to pull ahead — longer in expensive markets, shorter where prices are low. Planning to move in three years? Renting almost always wins. Staying fifteen? Buying usually does. Your time horizon is the single biggest variable, and any comparison that ignores it is flattering buying unfairly.
One more factor the formulas miss: flexibility has a price, and so does stability. A job offer in another city is worth more when you are not chained to a house you just bought; sleeping well because your housing payment cannot jump 15% next year is worth something too. Put a rough value on both before you decide.
The costs nobody puts in the brochure
- Buying hides: maintenance (roofs, boilers, plumbing — budget 1% of value yearly), transaction costs of 2–5% each time you buy and ~6% agent fees when you sell, plus the opportunity cost of the down payment sitting in bricks instead of investments.
- Renting hides: annual rent increases, zero equity built, and less control — the landlord can sell or decline to renew. There is also a real, non-financial value in stability that spreadsheets underrate.

Is renting really “throwing money away”?
No. Rent buys you housing, flexibility, and freedom from maintenance risk — and the money you do not tie up in a down payment can be invested. Plenty of lifelong renters who invest the difference retire wealthier than buyers who stretched too far.
How much house can I actually afford?
A common guideline: keep total housing costs under 28% of gross income and total debt payments under 36%. Check yours with our house affordability calculator.
Does buying always beat renting long-term?
Usually, but not always. It depends on price-to-rent ratios in your area, how long you stay, and what returns you would have earned investing instead. In very expensive cities, renting + investing can win even over decades.
