Rent vs Buy a Home: The 2026 Guide

The 60-second rule

Buying wins when you stay put; renting wins when you move. At typical 2026 numbers \— a $450,000 home, 20% down, 7.0% mortgage, $2,400 rent, 10 years \— the buy path costs $306,899.97 and renting costs $331,959.72: buying wins by $25,059.76. But sell after only 3 years and renting wins by $30,923.95, and at an 8.5% mortgage rate renting wins by $29,744.78 over the same decade. The break-even usually lands at 5\–7 years. Shorter: rent. Longer: buy. Run the comparison calculator with your numbers first; then read on for what the headlines hide.

The worked example, line by line

Buy path, 10 years: $90,000 down payment + $9,000 closing costs + ($2,395.09/month mortgage \× 120 = $287,410.68) + $49,500 property tax + $18,000 insurance + $45,000 maintenance + $95,747.98 of foregone 7% returns on the cash you sank into the house = $594,688.82 out the door. Then you sell: $634,769.44 home value (3.5%/yr appreciation) \− $308,924.58 remaining loan \− $38,086.17 selling costs (6%) = $287,758.70 of walk-away equity. Net buy cost: $306,899.97.

Rent path, 10 years: $2,400/month growing 3%/yr \→ $330,159.00 of rent + $1,800 of renter\’s insurance = $331,959.72. Nothing to sell, nothing recovered \— but nothing sunk either: your $99,000 stayed invested, which is why the foregone-returns line sits on the buy side of the ledger.

Verdict: $331,959.72 \− $306,899.97 = buying wins by $25,059.76.

The psychological trap is comparing the $2,400 rent to the $2,395 mortgage payment and calling it a tie. It is not close: the true monthly cost of the house is about $3,333 once tax, insurance, and maintenance join in. Buying wins anyway here \— not because the monthly payment is lower, but because 10 years of amortization plus appreciation outrun the carrying costs. The mortgage payment is the least informative number on the page.

The 5% rule (the 10-second version)

From Ben Felix\’s famous breakdown: the unrecoverable costs of owning \— roughly 3% mortgage interest, 1% property tax, 1% maintenance \— total about 5% of the home\’s value per year, whether you have a mortgage or not (on a paid-off house the 3% is the return your equity gives up). Compare that to your annual rent. Rent < 5% of price \→ renting is likely cheaper. Rent > 5% of price \→ buying likely wins. At the defaults: $28,800 annual rent vs 5% \× $450,000 = $22,500 \— rent is higher, so the rule says buy, matching the full model\’s $25,059.76 verdict. It is a heuristic, not a proof \— run the full calculator when the margin is thin \— but it settles most arguments in seconds.

The break-even year (the number that actually matters)

Every buyer should know one number: the year their verdict flips. In the default example, renting wins by $30,923.95 at year 3 and buying wins by $25,059.76 at year 10 \— so the break-even sits somewhere in the middle, typically 5\–7 years at normal rates. Three forces push it later: a higher mortgage rate (more of each payment is interest, less becomes equity), higher transaction costs (the 8\–11% round trip of closing + selling must be amortized over your stay), and slower appreciation. Find yours by shortening the \“years you will stay\” input in the calculator until the verdict flips \— then ask yourself how sure you are about staying that long. If your job, relationship, or city is uncertain, add a year of safety margin to the renting side.

Two branches that flip the answer

The 3-year branch: sell after 3 years and renting wins by $30,923.95. This is not close, and the reason is arithmetic, not opinion: you paid ~$9,000 to buy, ~$86,000 of mostly-interest mortgage payments, and ~$38,000 to sell, while building only about $11,000 of principal equity. The first years of a mortgage are nearly pure interest \— at 7%, year one\’s $28,741 of payments builds roughly $3,500 of equity. Short stays are the single most expensive way to own a home.

The 8.5% branch: same house, same rent, but an 8.5% mortgage \— renting wins by $29,744.78 over 10 years. The extra ~$40,000 of lifetime interest erases the entire buy edge. This is the 2026 reality check: at 3% rates, buying was a layup; at 7\–8.5%, the math is a genuine contest. \“Date the rate, marry the house\” only works if you actually refinance when rates fall \— and refinancing costs another 1\–2% of the loan.

Three expensive mistakes

1. Comparing rent to the mortgage payment. The $2,395 P&I looks like a tie with $2,400 rent; the real comparison is ~$3,333 of monthly ownership cost against rent \— or better, the full 10-year totals the calculator computes. People who \“buy because the payment equals rent\” are comparing two different things and calling them equal.

2. Buying for a stay you will not finish. A 3-year ownership is a $30,923.95 mistake in the default example. New job cities, growing families, uncertain relationships \— if there is a real chance you move before year 5, rent and invest the difference. Flexibility has a price, and the calculator shows it: it is the rent-side total.

3. Ignoring the foregone return. The $99,000 of down payment + closing is not \“spent\” \— but it is sunk: at 7% it would have grown to ~$194,778 in 10 years. That $95,747.98 opportunity cost is the quietest line in the buy column and the one most analyses skip. Renting is not throwing money away; it is buying the market return on your down payment plus the option to leave.
