Rent vs buy in 2026: the 5% rule and the price-to-rent ratio

The cliché that breaks the math

Every rent-vs-buy conversation eventually runs into "but you're just throwing money away on rent." This is wrong about half the time. Buying a home isn't free — even after the mortgage is fully paid, you're still spending money each year on property tax, insurance, maintenance and opportunity cost on the equity locked in the house. Renting isn't purely waste; it's buying optionality and offloading those costs. The right question isn't "which is morally better" but "which costs less for your specific situation in your specific city."

Two frameworks answer it cleanly: the 5% rule (quick comparison) and the price-to-rent ratio (deeper analysis). Both reduce to a single number you can compute in two minutes.

The 5% rule, explained

Coined by Ben Felix (Canadian financial advisor), the 5% rule says: the cost of owning a home is roughly 5% of the home's value per year, broken down as:

• 1% property tax (varies — US average around 1.1%, some states higher, some lower)
• 1% maintenance (industry rule-of-thumb: budget 1% of home value per year for repairs over the long run, including the big-ticket items like roof, HVAC, plumbing)
• 3% cost of capital (the opportunity cost on the equity you have tied up in the house — the return you could have earned investing that money elsewhere, net of the housing-market appreciation you do capture)

If you're paying less than 5% of the home's value in annual rent, renting is cheaper. If you're paying more than 5%, buying is cheaper. The decision flips at the breakeven point.

Worked example: a $500,000 home

• 5% × $500,000 = $25,000 per year, or $2,083 per month
• If equivalent rent in the same neighborhood is below $2,083, renting is cheaper.
• If equivalent rent is above $2,083, buying is cheaper.

In most major US metros in 2026, the rent on a $500,000-equivalent home (3-bedroom in a mid-tier suburb) is in the $2,400–$3,200 range. That makes buying cheaper than renting — but only by a few hundred dollars per month, which can be more than offset by the friction of buying (closing costs, the 3-5 years it takes to amortize the transaction costs, the optionality lost).

The price-to-rent ratio: the deeper framework

For a more rigorous comparison, use the price-to-rent ratio (P/R): home purchase price divided by annual rent for an equivalent home. The interpretation:

• P/R below 15: buying is clearly favorable. The rent-equivalent is high enough that even after all ownership costs, buying wins.
• P/R 15–20: roughly even. Personal factors (stability, mobility, optionality) dominate the decision.
• P/R 20–25: renting is generally favorable unless you have strong reasons to commit (school district, multi-decade horizon, lifestyle).
• P/R above 25: renting is clearly cheaper. The rental yield is so low that owning rarely makes financial sense in the same property.

P/R ratios across major 2026 metros (approximate):

• San Francisco Bay Area: 28–35 (rent strongly favored)
• New York City: 22–30 (varies by borough; Manhattan above 30, outer boroughs lower)
• Los Angeles: 24–28
• Boston: 22–26
• Austin: 18–22
• Chicago: 14–18 (buying often favored)
• Detroit, Cleveland, Pittsburgh: 10–14 (buying strongly favored)
• London, UK: 28–35 (rent favored)
• Berlin, Germany: 30–40 (rent strongly favored)
• Madrid, Spain: 22–28

The ratio shifts with mortgage rates. When rates were 3% in 2021, P/R of 25 could still favor buying (low monthly carrying cost). At 2026 rates of 6–7%, the same P/R of 25 favors renting because each month's mortgage payment is meaningfully higher.

What the 5% rule and P/R ratio miss

Both frameworks treat the rent-vs-buy decision as a pure financial calculation. Real households face additional factors:

• Mobility: Renting is the optionality to move within 30 days. Buying locks you into the property until you sell, which can take 3–6 months in a normal market and longer in a downturn.
• Forced savings: A mortgage payment includes principal paydown. Most people don't voluntarily save the equivalent if they're renting. The "forced savings" of homeownership is real money you'll have when you sell, even if the math says renting is technically cheaper.
• Inflation hedge: A fixed-rate mortgage locks your housing cost in nominal terms. Rents rise with inflation. Over 10–20 years, this matters substantially.
• School districts and stability: Buying gives you a multi-year commitment to a neighborhood that matters for kids and community ties.
• Tax treatment: Mortgage interest is partially deductible in some jurisdictions (US, France). The standard deduction in 2026 reduces this benefit for most US filers (only itemizers see it), but it still moves the needle for high earners.

The right framework for your decision

1. Pick a specific property you'd buy. Note the asking price.
2. Find an equivalent property you'd rent in the same neighborhood. Note the asking rent.
3. Compute the P/R ratio: purchase price ÷ (annual rent).
4. Compute the 5% rule: 5% of purchase price ÷ 12. Compare to monthly rent.
5. If the math favors one direction by a wide margin (P/R below 15 or above 25), trust it.
6. If the math is close (P/R 15–20), make the decision on lifestyle factors — mobility, kids, commute, neighborhood ties.

The "rent is throwing money away" cliché doesn't survive the math. In high-P/R cities, renting is genuinely the cheaper financial choice. In low-P/R cities, buying makes sense. Both decisions are correct under their respective conditions; the wrong move is to make the choice on a cliché instead of running the numbers. Use the loan calculator for the mortgage side and the percentage calculator for the rent-equivalent comparison — five minutes of math saves a decade of regret either way.
