Buy vs. Rent
Buying wins long-term in most markets if you stay 5+ years and don't pay over rent equivalent. But mortgage interest, property tax, insurance, maintenance, and opportunity cost on the down payment add up fast. Run the actual numbers.
The short answer
Rent if you might move within about five years. Buy if you will stay longer and the payment is comfortable.
The cliché that renting throws money away is wrong, and it is wrong for a specific reason: a large share of an early mortgage payment is interest, which is just as gone as rent. In the first years you are mostly renting money from a bank rather than renting a house from a landlord.
The transaction costs are what actually decide it. Buying costs a few percent going in and 6% to 8% coming out in commission and closing costs. That has to be amortised over however long you stay, which is why the horizon matters more than the monthly comparison.
Below about five years the transaction costs usually swamp the equity you build. Beyond it, buying tends to pull ahead — and the longer you stay, the more decisively.
What tips it
The variables that actually move the answer, in rough order of impact.
| How long you stay | Decisive | Under 5 years the round-trip transaction costs rarely get recovered. |
|---|---|---|
| Price-to-rent ratio | Large | Where buying costs roughly twice equivalent rent, renting and investing the difference usually wins. |
| Opportunity cost of the deposit | Underrated | A down payment sitting in a house is not sitting in an index fund. |
| Maintenance | Persistent | About 1% of value a year, and it does not stop. |
A monthly payment comparison that omits maintenance, transaction costs and the opportunity cost of the deposit will always flatter buying.
Where people go wrong
- Comparing a mortgage payment against rent and stopping there.
- Forgetting the 6% to 8% cost of selling, which is only recovered by staying put.
- Ignoring maintenance, which averages about 1% of the home value every year.
- Assuming the mortgage interest deduction helps. Since the standard deduction rose, most households no longer itemise.
Common questions
How long do I need to stay for buying to make sense?
Commonly three to five years, and it depends on your market. The test is when the equity built plus any appreciation exceeds the round-trip transaction costs. In a high price-to-rent market that can stretch well past five years.
Is renting really throwing money away?
No more than mortgage interest is. In the early years of a loan most of the payment is interest, insurance and tax — none of which builds equity. What renting genuinely costs you is the appreciation and the principal paydown you would otherwise have captured.
What about the tax benefits of owning?
Much smaller than they used to be. The mortgage interest and property tax deductions only help if your itemised total exceeds the standard deduction, which for most households it no longer does. Treat them as a bonus if they apply rather than as part of the case.
| Buy | Rent | |
|---|---|---|
| Monthly cost | Predictable, capped (fixed-rate) | Subject to annual increases |
| Maintenance | ~1% of home value per year | Landlord's problem |
| Down payment / deposit | 5-20% of home price | 1-2 months rent |
| Tax benefits | Mortgage interest + property tax (if itemizing) | None |
| Building equity | Principal payments + appreciation | None |
| Flexibility to move | Sell or rent out — 1-3 months | End lease — typically 30 days |
| Hidden costs | Closing $8-15K, selling 6-8% commission | Renters insurance, parking, sometimes pet deposit |
| Break-even (years) | Typically 3-5 years | N/A — every year is fully consumed |
Choose Buy if
- You'll stay in the home 5+ years.
- Your monthly buy cost (PITI + maintenance) is within 25% of equivalent rent.
- You have a 6-month emergency fund AFTER the down payment.
- You value control and customization.
Choose Rent if
- You're likely to move within 3 years.
- You're in a high-cost area where buying costs 2x equivalent rent.
- You'd rather invest the down payment in index funds for higher returns.
- You value flexibility — career change, life change, geographic move.
