Rent vs. Buy a Home: How to Decide
A complete framework for the rent-or-buy decision — the true costs of each, the break-even horizon, opportunity cost, and how to run your own numbers.
“Renting is throwing money away” is one of the most repeated pieces of financial advice — and one of the most misleading. Buying can be the right move, but so can renting, and the answer depends on your numbers and your life, not a slogan. This guide gives you a complete framework to decide.
The true cost of buying
The mortgage payment is only the beginning. Owning a home carries costs renters never see:
- Down payment — typically 5–20% of the price, locked up in the home.
- Closing costs — often 2–5% of the price, paid upfront.
- Property tax and insurance — ongoing, and rising over time.
- Maintenance — a common rule of thumb is ~1% of the home’s value per year for repairs and upkeep.
- PMI — extra cost if you put down less than 20%.

This is an estimate of your monthly housing cost (often called PITI). Principal and interest use the fixed-rate amortization formula; PMI applies while your balance stays above 80% of the home price. Your actual rate, taxes and insurance depend on your lender, location and credit profile.

The true cost of renting
Renting looks simpler, and largely is: rent, renter’s insurance, and possibly utilities. But rent rises over time, you build no equity, and you’re exposed to your landlord’s decisions. The offsetting advantage is enormous flexibility and no exposure to home-price swings, maintenance surprises or transaction costs.
Opportunity cost: the piece everyone forgets
Here’s the argument “renting is throwing money away” misses entirely. When you buy, a large sum — the down payment and closing costs — is tied up in the house. When you rent, that same money can be invested. Over a long period, invested money compounds. If your down payment could earn 7% a year in the market, that forgone growth is a real cost of buying.
Try modelling it with the investment calculator: a $60,000 down payment invested for 10 years at 7% grows to well over $100,000. Buying only wins if your home equity and the value of housing yourself beat that.
The break-even horizon
The single most useful question is: how long will you stay? Buying has high upfront costs (down payment, closing) and high exit costs (agent fees, ~6%). You need enough time for appreciation and equity to overcome them. As a rough guide:
- Under ~3–5 years: renting usually wins — you may not recoup the transaction costs.
- Longer than ~5 years: buying often wins, especially as rent rises and your mortgage balance falls.
The exact number depends on your local market, so treat five years as a starting point, not a rule.
The 5% rule (a quick sanity check)
A handy shortcut: estimate the annual unrecoverable cost of owning as roughly 5% of the home’s value — about 1% property tax, 1% maintenance, and 3% cost of capital (mortgage interest plus opportunity cost). Divide by 12 for a monthly figure. If you can rent a comparable home for less than that, renting is financially competitive; if renting costs more, buying likely wins.
For a $400,000 home, 5% is $20,000/year, or about $1,667/month. If a similar home rents for less, renting deserves a serious look.
When buying makes sense
- You’ll stay put for five or more years.
- You have a stable income and a 20% down payment (or close), avoiding PMI.
- You have an emergency fund left after the down payment.
- You value stability and control over flexibility.
When renting makes sense
- Your timeline is short or uncertain (a job that may relocate you).
- Home prices in your area are high relative to rents.
- You’d rather invest the difference than tie it up in a house.
- You want to avoid maintenance and transaction costs.
Run your own numbers
Slogans can’t decide this — your inputs can. Start with the mortgage calculator to see the real monthly cost of buying, use the loan calculator for financing comparisons, and the investment calculator to value the opportunity cost of your down payment. Compare the total, honestly, over your realistic time horizon.
