What the price-to-rent ratio tells you, what owning costs beyond the mortgage payment, and how to find the year buying pulls ahead. General information, not personalized financial or tax advice.
Divide a typical home price in your area by a year of rent for a comparable place. A $400,000 home in a market where that home rents for $1,800 a month gives 400,000 ÷ 21,600 = 18.5. The number is not a verdict, but it sorts markets into three very different conversations. Under about 16, buying tends to pull ahead quickly. Over about 24, renting tends to stay ahead for longer than most people stay anywhere. In between, it genuinely depends on the details, which is where the rest of this page earns its keep.
The reason the ratio matters so much is that it sets the size of the gap the rest of the maths has to close. Buying starts deep in the hole: the down payment and closing costs leave immediately, and the first years of a mortgage are mostly interest. Every month of ownership then claws a little of that back, partly through principal, partly through appreciation, and partly because your housing payment stops rising while rent does not. A low ratio means each month claws back more. A high ratio means it claws back less, so the hole takes longer to climb out of.
Running the same $1,800 rent against different home prices shows how sharply this moves. These are the breakeven years the rent vs. buy calculator produces holding everything else at its defaults — 20% down, a 6.5% rate, 3.5% appreciation, 3% rent growth, and the money not spent on a down payment invested at 6%.
On that $400,000 home with 20% down at 6.5%, principal and interest come to $2,023 a month, which looks like a manageable step up from $1,800 of rent. It is not the number to compare. Property tax at 1.1% adds $367 a month, insurance at $1,700 a year adds $142, and setting aside 1% of the home's value annually for maintenance adds $333. That is $2,865 a month before anything breaks, against $1,800 to rent the equivalent — and the maintenance line is an average, not a bill that arrives in even monthly pieces.
Then there is the cash that leaves before you own anything. A 20% down payment is $80,000, and closing costs at 3% are another $12,000: $92,000 gone on day one. The Consumer Financial Protection Bureau's list of what closing costs consist of is long and unglamorous — appraisal fees, title insurance, government recording taxes, and prepaid property tax, insurance and interest — and none of it buys equity. Rent, for comparison, usually asks for a deposit and a first month.
Selling costs are the ones that quietly decide short ownerships, because they scale with the home's price rather than with your equity. At 7%, selling that home after a year of 3.5% appreciation costs about $28,980 — more than a third of the down payment, paid out of the proceeds. That single line is why buying with a short horizon so reliably loses: you pay a percentage of the whole house to get out, having owned only a sliver of it.
Take the baseline: $1,800 rent, a $400,000 home, 20% down at 6.5% on a 30-year loan, 3.5% appreciation, 3% rent growth, and the $92,000 you did not spend on buying invested at 6% instead. Buying is $41,695 behind after one year. It is still $36,016 behind at seven years. At twelve years the gap has narrowed to $7,917, and buying finally pulls ahead in year 13. By year 15 it is ahead by $20,639, and it keeps widening from there.
Two things make the early years so lopsided. The first is the round trip: $92,000 to get in, roughly $29,000 to get out, and none of it recoverable. The second is amortization. Of the $24,272 paid on that mortgage in year one, $20,695 is interest and $3,577 is principal — under 15% of the payments buy any of the house. How interest works covers why an amortizing loan front-loads interest that way, and the mortgage calculator shows the same split for your own numbers.
Against that, a median US homeowner in 2025 had been in their home 12 years, according to Redfin's analysis of county records — up from 6.5 years in 2005. So a breakeven of 13 years is not automatically a verdict against buying; it is roughly the length of a typical ownership. It does mean the decision hangs on a genuinely uncertain forecast about your own life, which is worth being honest about rather than assuming the longest case.
Changing one assumption at a time from that 13-year baseline shows which inputs carry real weight and which barely register. The mortgage rate and the appreciation rate move it by years. The down payment size and the selling-cost percentage move it by about one.
One input deserves singling out, because it is the one people leave at whatever the tool defaults to. Raise the return on the invested down payment from 6% to 8% and buying never breaks even within 40 years in this scenario. That is not a claim that renting wins; it is a warning that the comparison quietly depends on an assumption about the stock market that nobody can make confidently. Two honest people can run identical housing numbers, disagree only about that figure, and reach opposite conclusions. Treat any rent-versus-buy answer that does not show you its assumed investment return as incomplete.
Mortgage interest and property tax are itemized deductions, which means they only help to the extent they beat the standard deduction — $16,100 for a single filer in 2026 and $32,200 for a married couple filing jointly. A couple whose mortgage interest, property tax and everything else adds up to less than $32,200 gets exactly nothing from the deduction, because they will take the standard deduction instead. That describes most buyers, and it is the single most oversold argument for buying.
Where it does apply, there are ceilings. Interest is deductible on up to $750,000 of home acquisition debt for loans taken after 15 December 2017, or $1,000,000 for older debt. State and local taxes, property tax included, are capped as a group: the cap rose to $40,000 for 2025 and increases 1% a year through 2029, making it $40,400 for 2026, with a phase-down for high incomes and a scheduled return to $10,000 in 2030. How taxes work covers the difference between a deduction and a credit, which is worth understanding before weighing either.
The genuinely large tax benefit of owning is the one nobody advertises, because it arrives at the end. If you have owned and lived in the home for at least two of the five years before selling, you can exclude up to $250,000 of gain from tax, or $500,000 filing jointly. On a home that appreciates meaningfully over a long ownership, that exclusion is worth far more than the interest deduction ever was — and it rewards exactly the long hold the breakeven maths already favours.
Owning throws money away too, under names that sound more respectable. In year one of the example, $20,695 went to interest and $3,577 to principal; property tax, insurance and maintenance add roughly $842 a month on top, and selling costs about $29,000 on the way out. Rent buys housing. Interest buys the use of someone's money. Neither comes back.
You need 20% to avoid private mortgage insurance, which is a real cost but a temporary one: you can request cancellation once the balance is scheduled to reach 80% of the original value, and the servicer must drop it automatically at 78%. Dropping to 5% down in the example moved breakeven from year 13 to year 12, because the cash you did not tie up is earning something instead.
It wins eventually in most scenarios, but "eventually" is doing heavy lifting. At a price-to-rent ratio of 28, breakeven lands at year 31 — longer than the median homeowner stays anywhere, and long enough that the question is really about the next three decades of your life rather than about housing.
Most buyers never see it. Mortgage interest only helps if your itemized deductions clear the standard deduction, which is $32,200 for a couple in 2026, and the state and local portion is capped besides. The tax benefit that does reliably matter is the capital gains exclusion at sale, which requires owning for years — so it is a reason to hold, not a reason to buy.
Tax figures are set by the IRS and adjusted most years; these apply to the 2026 tax year. The capital gains exclusion requires meeting both the ownership and use tests — two years out of the five before the sale.
Renting wins when you are likely to move before the breakeven year, when the local price-to-rent ratio is high enough to push that year out past any horizon you can honestly forecast, when buying would consume the cash reserve that keeps a bad month from becoming a crisis, or when the payment would be a stretch that only works if nothing goes wrong. It also wins when the down payment would otherwise be invested and you would actually invest it — that last condition matters, because the comparison assumes the money goes somewhere productive rather than being spent.
Buying wins when the ratio is low, when you are reasonably confident about staying, when the all-in monthly cost fits comfortably rather than exactly, and when you have a reserve left over afterwards. Two things help regardless: a stronger credit score lowers the rate, which is one of the biggest movers of the breakeven year, and how credit scores work covers what actually moves it. Run your own numbers in the rent vs. buy calculator, change one assumption at a time, and notice how far the answer moves — a conclusion that survives a plausible range of assumptions is worth acting on, and one that flips when you nudge the appreciation rate is not a conclusion at all.
Nothing is saved or sent anywhere; this just checks your answers in the page itself.
The appreciation, rent growth and investment return rates in the examples are assumptions for illustration, not projections; real markets deliver none of them smoothly, and the breakeven year moves substantially when they change. Property tax rates, insurance costs and selling costs vary widely by state and by transaction. The state and local tax cap figure for 2026 reflects the 1% annual increase written into current law rather than a published IRS table. This page is general information, not financial or tax advice.
