Is Buying Always Better Than Renting? No — Here’s When Renting Wins
Last updated July 18, 2026
Buying is not always better than renting. In our model’s default US scenario (a $420,000 home versus $2,100 rent, 20% down, 6.5% mortgage, 10-year stay), renting and investing the difference ends roughly $67,000 ahead — while dropping the rate to 4% flips the verdict to buying by about $38,000. “Rent is throwing money away” isn’t analysis; it’s a slogan, and the numbers below show exactly when it’s wrong.
Is rent really “throwing money away”?
No. Rent is unrecoverable, but so is most of what an owner pays. In our model’s default first year, roughly $2,400 of the owner’s $3,067 monthly cost — mortgage interest, property tax, and insurance — buys no equity at all, before even counting maintenance. The comparable renter pays $2,115 all-in. Both are “throwing money away.” The owner throws more.
Here is year one of our default scenario, side by side (20% down on a $420,000 home, 6.5% 30-year mortgage, 1.1% property tax, 1% annual maintenance):
| Year-1 monthly cost | Owner | Renter |
|---|---|---|
| Mortgage principal & interest | $2,124 | — |
| Property tax | $385 | — |
| Home / renters insurance | $208 | $15 |
| Maintenance (1% of value per year) | $350 | — |
| Rent | — | $2,100 |
| Total | $3,067 | $2,115 |
That $2,124 payment feels like saving, but a young 6.5% mortgage is mostly interest: about $1,800 a month of it goes to the bank in year one, not into equity. Add $385 of property tax and $208 of insurance and you’re at roughly $2,400 a month that is exactly as gone as rent — more than the renter’s entire housing bill. The $350 maintenance budget is unrecoverable too: it keeps the roof from leaking; it doesn’t make the house worth more. Only the thin principal slice and any appreciation build wealth. This is the same logic behind the well-known 5% rule — our 5% rule calculator turns it into a 30-second estimate.
What is the down payment actually costing you?
Cash locked in a house can’t compound anywhere else. Our default buyer hands over $96,600 upfront — $84,000 down plus $12,600 (3%) in closing costs. Invested at 7% instead, that same money grows to about $190,000 over 10 years. The ~$93,000 of foregone growth is a real cost of buying that never shows up on a bill.
The buyer does get something for it: leveraged exposure to the house, which at 3% appreciation is worth about $564,000 in year 10. But carrying that exposure costs 6.5% interest on the borrowed 80%, and exiting costs 6% of the sale price in selling costs. Net out everything — equity, appreciation, selling costs, even capital-gains tax on the renter’s portfolio — and the renter-investor still finishes about $67,000 ahead over the decade. One reason our result is more even-handed than most: as documented in our methodology, opportunity cost runs symmetrically, so whichever side pays less in a given month is credited with investing the difference. Most calculators only credit the renter.
When does renting win?
Renting tends to win when rent is low relative to local prices, when you may move within about six years, when mortgage rates are high, in expensive metros, and when you genuinely invest the savings. In our default scenario — all five mildly true — renting finishes about $67,000 ahead over 10 years; in a pricey metro the gap can reach six figures.
1. Rent is cheap relative to price. Our default renter pays 0.5% of the home’s value per month ($2,100 on $420,000 — a price-to-rent ratio near 17). At 6.5%, our model’s tipping point is $2,468: below that rent, renting wins, and the actual $2,100 clears it with room to spare.
2. You might move. Shorten the stay to 5 years and renting wins by about $49,000 — the 3% closing costs going in and 6% selling costs coming out never get amortized. Short stays sink buying even when everything else favors it: in our 4% variant, buying doesn’t break even until year 6.
3. Mortgage rates are high. Rates move the goalposts more than any other input:
| 30-year rate | Rent at which buying starts to win* | Verdict at the actual $2,100 rent |
|---|---|---|
| 4% | $1,890 | Buying wins |
| 5% | $2,067 | Buying wins (barely) |
| 6% | $2,340 | Renting wins |
| 6.5% | $2,468 | Renting wins |
| 7% | $2,590 | Renting wins |
| 8% | $2,830 | Renting wins |
*Our model: $420,000 home, 10-year stay, all other inputs at defaults.
Same house, same rent: at 6.5%, renting wins by ~$67,000; at 4%, buying wins by ~$38,000. If you’re deciding this year, our 2026 guide covers where current rates leave the math.
4. You’re in an expensive metro. A $1.1M home renting for $3,800 (0.35% per month) leaves renting ahead by roughly $560,000 over 15 years in our model — and that’s modeling a married couple who itemizes. Tax breaks don’t rescue it: with 20% down the loan is $880,000, so interest above the $750,000 deduction cap earns nothing, and the 2026 SALT cap ($40,400) limits the property-tax deduction.
5. You actually invest the difference. Every number above assumes the renter invests the $952 monthly gap plus the $96,600 upfront at 7%. That assumption deserves its own section — see the catch below.
When does buying win?
Buying tends to win when rent runs high relative to price (roughly 0.7% of the home’s value per month or more), when you stay well past the break-even year, when you lock in a low rate, when a mortgage is the only saving you’d realistically do, and when you’d pay real money for stability.
High rent-to-price markets. A $220,000 home renting for $1,600 — 0.73% per month, price-to-rent near 11 — flips the verdict: buying wins the 10-year comparison in our model. Affordable metros where rents run proportionally high are buying’s home turf.
Long stays — with a caveat. At a 4% rate, buying breaks even in year 6 and the lead grows every year after. But time only compounds an advantage that already exists: run the default 6.5% scenario for 30 years and renting wins by about $389,000, because the renter’s invested difference compounds too. When does buying beat renting? maps the break-even math in detail.
Low rates. At 4%, buying wins by ~$38,000. Worth knowing: that verdict is fragile — a one-point change in appreciation or the mortgage rate flips it — while the default 6.5% renting verdict survives any single ±1-point assumption change in our sensitivity runs.
Forced savings. Principal payments happen whether you feel disciplined that month or not. For many households, that automation is worth more than a theoretical extra point of return.
Stability has value. The $2,124 principal-and-interest payment is frozen for 30 years, while our default rent grows 2.5% a year — about $2,620 by year 10. Owning is rent control you sell to yourself, plus no landlord and no forced move. (The converse holds too: if you hold an actual rent-controlled lease, renting gets dramatically harder to beat.)
The catch: most renters don’t invest the difference
The renting-wins math has a behavioral prerequisite. Our model credits the renter with investing the $96,600 they didn’t put down, plus the $952 monthly gap, at 7%. Renters who spend that difference instead don’t get the $67,000 win — they get the worst of both worlds: no equity and no portfolio.
The stakes are large. The pre-tax growth on the upfront cash alone (~$93,000 over 10 years at 7%) is bigger than renting’s entire ~$67,000 margin — if that money idles in checking and the monthly gap disappears into lifestyle, the verdict flips to buying by default. Owning wins for many people not because the arithmetic favors it but because a mortgage is the only savings plan they’ll actually follow. So be honest with yourself: if you won’t automate transfers into investments the way a bank automates your mortgage payment, weight the buy side. To see the sensitivity directly, set the calculator’s investment return to what un-invested cash would really earn — the margin evaporates fast.
