The Price-to-Rent Ratio, and What It Says About Your City

The price-to-rent ratio is a home’s price divided by a year of rent on a comparable home. A low number means houses are cheap relative to what they rent for, which favors buying. A high number means you pay many years of rent up front to own, which favors renting. The national figure in mid-2026 was about 18.7.

The ratio is useful because it takes two numbers you can look up in five minutes and turns them into a question about your city. Where it goes wrong is the reading. The cutoffs that get repeated online (under 15 buy, over 20 rent) have no interest rate in them, and the interest rate is what decides where the line falls.

What the ratio measures

Flip the ratio over and it becomes a yield. A ratio of 20 means a year’s rent is 5% of the price; a ratio of 12.5 means it is 8%. That is the return a landlord would collect before paying a single expense, and it is also the size of the bill you avoid each year by owning instead of renting the same house.

Against that 5% or 8%, an owner pays real costs: interest on the loan, the return the down payment would have earned elsewhere, property tax, insurance and upkeep. Price growth offsets part of those. When the rent you avoid is larger than those net costs, owning is cheaper. When it is smaller, renting is.

So the ratio is a quick read on one side of that comparison. It says nothing about the other side, which is why the same ratio can mean “buy” at 3% mortgage rates and “rent” at 7%.

Calculating it from a listing

The calculation is one division. The care goes into choosing the two numbers.

1. Price: the asking price of the house you would actually buy, or the recent sale price of one like it.
2. Rent: the monthly rent on a comparable home nearby. Same type of building, similar size and bedroom count, same neighborhood. Rental listings for houses are the source here, not the metro’s average rent.
3. Divide: price divided by twelve times the monthly rent.

Take a house listed at $360,000 on a street where a similar three-bedroom house is advertised for rent at $1,850 a month. A year of that rent is $22,200, and $360,000 divided by $22,200 is about 16.2. Read as a yield, the rent is 6.2% of the price. (These are example figures for the method, not market data.)

What the national number has done

The Census Bureau publishes two medians each quarter from its Housing Vacancy Survey: the asking rent on vacant units for rent and the asking sales price on vacant units for sale.^[1] Divide one by twelve times the other and you get a national price-to-rent ratio going back to 1988.

The shape matches the last housing cycle. In 2007 the median asking price was $187,600 against a median asking rent of $665 a month, a ratio of 23.5, the highest annual figure in the series. By 2016 the price was $158,900 while rent had risen to $856, and the ratio was 15.5.^[1] In the second quarter of 2026 it was $343,800 against $1,531, or 18.7: higher than any year from 1988 through 2004, and well below the 2007 peak.

One caution before reading too much into these medians. The Census Bureau limits the sales-price figure to one-unit homes, while the rent figure covers rental units of every kind, most of which are apartments.^[2] That is the house-against-apartment mismatch from the box above, at national scale. The level of the ratio is a rough guide; the movement over time is the more reliable signal, because the mismatch is there every year.

Why the national figure hides the answer

Nobody buys a house in “the United States,” and the four census regions show how wide the spread is. In the second quarter of 2026:^[1]

In the West, the median home costs 26 years of median rent. In the Midwest it costs about 16. A household weighing the same decision in those two places is looking at a 10-point gap before considering a single detail about the house. Individual metros spread wider: the 2005 paper behind the next section put San Francisco at about 33, from 2000 Census values and rents, and found that cities with high ratios tend to stay high while the low ones stay low.^[3]

That persistence is the reason a national ratio settles nothing. Expensive markets stay expensive relative to rent partly because buyers there expect faster price growth, and expected growth is one of the inputs to the cutoff.

The cutoff your interest rate sets

In 2005, the economists Charles Himmelberg, Christopher Mayer and Todd Sinai laid out the comparison the ratio stands in for. They add up the yearly cost of owning per dollar of house price, which they call the user cost, and show that the price-to-rent ratio at which owning and renting cost the same is one divided by it.^[3] The user cost has six parts:

• the return the money tied up in the house could earn instead, at the 10-year Treasury rate,
• plus the property tax rate,
• minus the income tax saved by deducting mortgage interest and property tax,
• plus maintenance and depreciation,
• minus expected price growth,
• plus a premium for the extra risk of owning.

Their illustration used a 4.5% Treasury rate, a 5.5% mortgage rate, a 1.5% property tax rate, 2.5% for depreciation, a 25% tax rate, a 2% risk premium and 3.8% expected price growth. That gave a user cost of 5.0% and a break-even ratio of 20.^[3]

Keep every one of their assumptions and change only the two rates to today’s: the 10-year Treasury yield was 5.15% on October 19, 2026,^[5] and the average 30-year fixed mortgage was 7.40%.^[4] The answer now depends on whether the buyer itemizes. The deduction term only exists for households whose itemized deductions beat the standard deduction, which for 2026 is $32,200 for a married couple and $16,100 for a single filer.^[6]

For the itemizer, the line sits at 19.5, close to where the paper put it in 2005. For the household on the standard deduction it drops to 13.6, below the national ratio in every year of the Census series since 1994. Which group you are in is not a detail: in the full rent-versus-buy arithmetic, a married couple buying the median home with 10% down fell just short of the standard deduction, so the tax saving was worth nothing to them.

The authors call expected price growth one of the most critical and least understood inputs, and it moves the cutoff more than any other. Raise it by one point to 4.8% and the break-even goes to 24.2 for the itemizer and 15.7 for the standard-deduction buyer. Cut it to 2.8% and they fall to 16.3 and 12.0. A ratio of 26 in the West is consistent with owning only if buyers there expect prices to keep rising well ahead of the national pace.

The risk premium is the other soft input. The paper took its 2% from earlier research and noted in a footnote that it may be too high, because owning also insures you against future rent increases.^[3] If you plan to stay put for a long time, a fixed payment is worth something that a one-year formula does not see, and a lower premium raises your break-even ratio. If your job or household could move within a few years, the premium belongs at the full 2% or above.

Reading your own number

Back to the $360,000 house that rents for $1,850. Its ratio of 16.2 is below the itemizer’s 19.5 and above the standard-deduction buyer’s 13.6. Flipped around, the itemizer breaks even at any rent above about $1,538 a month, while the household on the standard deduction needs the comparable rent to be about $2,206 before buying wins on cost. Same house, same rent, opposite answers.

To use the ratio on a real decision, swap the paper’s assumptions for yours:

• Property tax: divide your county’s bill for a similar house by its assessed or sale price.
• Upkeep and insurance: the 2.5% in the formula is generous for a new house and thin for an old one. Get a real insurance quote rather than a rule of thumb; the reasons a renewal climbs faster than inflation apply to a first policy too.
• Taxes: estimate your first-year interest plus property tax and check whether it clears the standard deduction. If it does not, the tax saving term is zero.
• Expected growth: pick a number you would defend to a skeptic, then try it one point lower.
• How long you stay: the formula is a one-year comparison and leaves out the cost of buying and selling, which only years of ownership recover.

If the ratio clears the break-even with room to spare, the next question is whether the payment fits: what a lender approves against what your budget can carry is a separate test, and plenty of houses pass one and fail the other. Both start from what you actually spend on housing now, rent plus renters insurance plus utilities, which is the number that decides whether the rest of a budget has room in it.

That figure is easy to get wrong from memory and easy to read from a ledger. If your accounts are connected, the spending view groups a year of rent and housing bills by category, which gives you the denominator for your own ratio and the starting point for everything after it.
