Rent vs. Buy in 2026: Calculating Your True Housing Horizon
How mortgage rates, price-to-rent ratios, and how long you plan to stay determine whether renting or buying actually wins — with real numbers across 10 U.S. cities.

Key takeaways
- The price-to-rent ratio — median home value divided by annual rent — is a quick screen for a metro: under roughly 15 tends to favor buying, 16-20 is situational depending on how long you'll stay, and above roughly 21 tends to favor renting unless you plan to stay 10+ years.
- The gap between cities is enormous: Memphis, TN sits at an 11.1 ratio (strongly buy-favoring) while Seattle, WA sits at 37.7 (strongly rent-favoring) — more than three times higher, on this site's own current housing data.
- A ratio is a screening tool, not a verdict — it ignores property tax, insurance, HOA fees, and the fact that mortgage rates move, so always re-check current rates and a specific property's full carrying cost before deciding.
- Once you've narrowed down a destination, see what income it actually takes to buy or rent comfortably there on that city's own salary-needed page, and pair this guide with The Hidden Costs of Moving for the costs that show up after closing or signing a lease.
Price vs. rent isn't the real question
Most rent-vs-buy advice starts and ends with a single comparison: is the monthly mortgage payment higher or lower than the monthly rent? That comparison is incomplete, because it leaves out the variable that actually decides who wins — how long you plan to stay. A city where buying costs more per month than renting can still be the better financial decision if you're putting down roots for a decade, because the equity you build and the rent increases you dodge accumulate over time. A city where buying looks cheap on a monthly basis can still be the wrong call for a two-year stay, once closing costs and selling costs are factored in.
The price-to-rent ratio is the tool that captures this trade-off in a single number, because it's built from the same two inputs — purchase price and rental cost — normalized against each other rather than compared as raw monthly payments. It won't tell you exactly what to do, but it will tell you, city by city, whether the math is tilted hard toward buying, tilted hard toward renting, or sitting in a gray zone where your personal timeline is what actually breaks the tie. That's the "true housing horizon" this guide is built around: not just what a home costs versus what rent costs, but how that ratio interacts with how many years you'll actually be there.
The price-to-rent ratio, explained
The ratio itself is simple to calculate: take a market's median home value and divide it by its median annual rent (monthly rent times 12). Dallas, TX is a real example from the table below: a $270,700 median home value divided by $15,660 in annual rent ($1,305 a month times 12) works out to a 17.3 price-to-rent ratio. The higher the number, the more expensive buying is relative to renting in that specific market, and vice versa.
There's a widely-used general guideline, not specific to this site, for reading that number: a ratio under roughly 15 tends to favor buying, since the purchase price is low enough relative to rent that a mortgage payment typically pencils out favorably even over a moderate holding period. A ratio of 16 to 20 is genuinely situational — it depends heavily on how long you plan to stay, since it usually takes several years of appreciation and equity-building to make buying come out ahead of renting at that level. Above roughly 21, the guideline tilts toward renting unless you're confident you'll stay 10 years or more, because the purchase price is high enough relative to rent that it takes a long holding period for buying's advantages to overcome its higher carrying cost and transaction costs.
Ten cities, ten verdicts
Applying that ratio to ten real U.S. metros shows just how differently this plays out depending on where you're looking. At the low end, Memphis, TN posts an 11.1 ratio — solidly in buy-favoring territory — thanks to a median home value of just $139,600 against a median rent of $1,050 a month. At the high end, Seattle, WA posts a 37.7 ratio, more than three times Memphis's figure, driven by a median home value of $879,900 against rent of $1,945 a month that hasn't kept pace with the purchase price.
The eight cities in between spread across the whole range the rule-of-thumb describes. Dallas, TX sits just above the buy-favoring threshold at 17.3. Tampa, FL (19.5) and Nashville, TN (21.0) sit right at the edge of the situational band, which makes their verdict depend heavily on your own timeline — worth comparing directly, for instance by looking at how Nashville and Memphis stack up side by side. Phoenix, AZ (21.4), Las Vegas, NV (22.4), Miami, FL (24.2), and Austin, TX (24.8) all land in rent-favoring territory, while San Diego, CA (31.4) approaches Seattle's extreme. The full table below lists all ten cities with the exact figures behind each verdict.
| City | Median home value | Median rent/mo | Price-to-rent ratio | Est. monthly P&I (20% down, 7.03%, 30-yr) |
|---|---|---|---|---|
| Memphis, TN | $139,600 | $1,050 | 11.1 | $745 |
| Dallas, TX | $270,700 | $1,305 | 17.3 | $1,445 |
| Nashville, TN | $351,400 | $1,392 | 21.0 | $1,876 |
| Tampa, FL | $333,200 | $1,422 | 19.5 | $1,779 |
| Phoenix, AZ | $340,200 | $1,322 | 21.4 | $1,816 |
| Las Vegas, NV | $365,300 | $1,356 | 22.4 | $1,950 |
| Miami, FL | $433,900 | $1,494 | 24.2 | $2,316 |
| Austin, TX | $461,500 | $1,549 | 24.8 | $2,464 |
| San Diego, CA | $783,300 | $2,080 | 31.4 | $4,182 |
| Seattle, WA | $879,900 | $1,945 | 37.7 | $4,697 |
Two worked examples
Memphis is the clearest buy-favoring case in the table. At a median home value of $139,600, the estimated principal-and-interest payment — 20% down, a 30-year fixed term, at Freddie Mac's current 7.03% national average rate, the same assumptions this site's own affordability tools use elsewhere — comes out to about $745 a month. Run that figure against the 28% front-end debt-to-income guideline this site uses for purchase affordability: a household would need about $31,929 a year in gross income for that $745 monthly payment to clear the 28% threshold. Combined with an 11.1 price-to-rent ratio, Memphis strongly favors buying even for a buyer who doesn't plan to stay for a full decade.
Seattle sits at the opposite extreme. Its $879,900 median home value produces an estimated principal-and-interest payment of about $4,697 a month under the same 20%-down, 7.03%, 30-year assumptions. Measured against that same 28% front-end debt-to-income guideline this site uses for purchase affordability, clearing a $4,697 monthly payment at the 28% threshold would require roughly $201,300 a year in gross income — on principal and interest alone, before property tax, insurance, or HOA dues. Paired with a 37.7 price-to-rent ratio, Seattle strongly favors renting unless you're confident you'll stay in the home for 10 years or more, since that's roughly the horizon the rule-of-thumb assumes it takes for ownership's advantages to outweigh a purchase price this high relative to rent.
What the ratio doesn't capture
The price-to-rent ratio, and the P&I figures above, are a screening tool, not a complete cost comparison. Every P&I estimate in this guide is principal and interest only — it excludes property tax, homeowner's insurance, PMI, and HOA dues, the same explicit limitation this site's own affordability calculations document, because those costs vary too much by city and property to assume a single national average without quietly making a "city-specific" number not actually city-specific. Depending on the city, those excluded costs can add several hundred dollars a month on top of the P&I figures shown here, which can meaningfully shift a city that looks borderline in the table above.
Mortgage rates also move. Every P&I figure in this guide assumes Freddie Mac's Primary Mortgage Market Survey national average rate as of late September 2026 (7.03%) — a rate that will drift as the broader rate environment changes. A rate a point higher or lower changes the monthly payment meaningfully even at the same home price, which can shift a city from one side of the rule-of-thumb bands to the other. Before making a final rent-vs-buy decision, re-check the current rate, get a real quote that includes property tax and insurance for the specific property you're considering, and check that city's own salary-needed page — for example Seattle's or Memphis's — for the fuller income picture beyond principal and interest alone.
