The short answer
Buying usually works out cheaper only if you stay long enough — often somewhere between 5 and 10 years — to outweigh the costs of buying and selling. Stay a short time and renting tends to win. The break-even point depends mostly on how long you stay, local rents versus prices, and how fast home values grow.
“Rent is dead money” is one of the most repeated lines in personal finance, and it's only half true. Rent buys you a place to live — exactly like the interest, property tax, insurance and repairs a homeowner pays, which are just as “dead”. The real question is which set of unrecoverable costs is smaller for you.

Compare unrecoverable costs, not rent vs mortgage
Comparing your rent with a mortgage payment is misleading, because part of the mortgage payment is savings — it pays down the loan and you get it back when you sell. What you never get back is:
| Renting | Owning |
|---|---|
| Rent | Mortgage interest |
| Renter's insurance (small) | Property tax, home insurance |
| — | Maintenance and repairs (often 1–2% of the value a year) |
| — | Buying costs: closing costs, stamp duty or transfer tax |
| — | Selling costs: agent fees and legal costs (often 5–6% in the US) |
| Lost growth on money not invested | Lost growth on the deposit tied up in the house |
That last row is easy to forget. A $80,000 deposit sitting in a house isn't earning anything else. A renter can invest it.
A worked example
Take a $400,000 home with 20% down at a 6.5% mortgage rate, against renting a similar place for $2,000 a month. Assume home prices and rents both rise 3% a year, the renter invests the deposit at 5%, and buying and selling costs are 3% and 6%.
| Stay for | Net cost of buying | Net cost of renting | Cheaper |
|---|---|---|---|
| 3 years | $93,000 | $60,000 | Renting |
| 5 years | $130,000 | $102,000 | Renting |
| 7 years | $165,000 | $146,000 | Renting |
| 10 years | $213,000 | $217,000 | Buying (just) |
| 15 years | $283,000 | $347,000 | Buying |
In this example buying pulls ahead around year 10. But nudge one assumption and the picture changes: at $2,500 rent, buying wins after about 5 years; at $2,800, after 4. Rent relative to price is often the single biggest factor.
A quick check: the price-to-rent ratio
Divide the home price by a year's rent for a similar place:
- Under about 15: buying tends to look good.
- 15–20: it could go either way — run the full comparison.
- Over about 20: renting is often the cheaper way to live there.
Our example is $400,000 ÷ $24,000 = 16.7 — right in the “depends” zone, which is why the answer took ten years to appear.
What the numbers can't tell you
- Flexibility. If there's a real chance of moving for work or family within a few years, the buying and selling costs alone can sink the case for buying.
- Stability. Owning protects you from rent rises and from a landlord deciding to sell. For families settled in an area, that's worth something.
- Forced saving. Mortgage payments build equity automatically. Renters only come out ahead if they actually invest the difference — and many don't.
- Effort and risk. A new roof or boiler is the owner's problem, and it rarely arrives at a convenient time.
Frequently asked questions
Is renting a waste of money?
No more than mortgage interest, property tax and repairs are. Compare the costs you can't get back on each side, not rent against a whole mortgage payment.
How long do you need to stay for buying to be worth it?
Commonly 5–10 years, but it varies a lot with local rents, prices and growth. The rent vs buy calculator finds the break-even year for your numbers.
What's a good price-to-rent ratio for buying?
Below about 15 usually favors buying; above about 20 usually favors renting.
Does a rising housing market mean I should buy?
Faster price growth helps buying, but nobody knows future prices. Test a few growth rates — if buying only wins with optimistic growth, be careful.
