How we built this ranking
Home value. The purchase price is the Zillow Home Value Index (ZHVI) for September 2026: the typical value of homes in the 35th to 65th percentile range in each city, covering single-family homes and condos, smoothed and seasonally adjusted.
Rent. The monthly rent is the Zillow Observed Rent Index (ZORI) for September 2026: the typical market asking rent across all rental homes and apartments, smoothed and seasonally adjusted. Using Zillow for both value and rent keeps the two figures current and measured the same way.
Property tax. We apply each city's effective tax rate (median real estate taxes ÷ median home value, U.S. Census Bureau ACS 2024 5-year estimates) to the current home value.
Insurance. The NAIC 2023 statewide average homeowners (HO-3) premium plus 25%, reflecting the Insurance Information Institute's estimate that landlord policies cost about 25% more.
Mortgage rate. 7.18%, the Freddie Mac Primary Mortgage Market Survey 30-year fixed average for the week of November 5, 2026. Investment property loans usually cost somewhat more, which would make cash flow harder, not easier; see the sensitivity table above.
Everything else is identical for every city: 25% down, a 30-year term, closing costs of 2% of the price, 5% vacancy, 5% maintenance, 8% management and 5% capital reserves. Cities are ranked by modeled cap rate, using the same formulas as our rental property calculator (methodology).
Quality checks
A city is held out for review when its Zillow rent moved more than 30% in a year or sits more than 60% above or 40% below HUD's Fair Market Rent, since smoothed indexes rarely move that much. Every Zillow rent is compared with HUD's Fair Market Rent for the same area (see above). Zillow cities are matched to Census places by state and name. Ambiguous names are skipped rather than guessed, and any match whose current value or rent is less than half or more than three times the Census median is rejected as a likely mismatch. 6 cities with at least 100,000 residents are excluded because Zillow does not publish both a value and a rent index for them: South Fulton, Enterprise, Paradise, Spring Valley, Sunrise Manor, The Woodlands.
Held out for data review this month: Abilene (Zillow rent up 31% in a year), Brownsville (Zillow rent 63% above HUD's Fair Market Rent). These cities return to the ranking automatically once the figures are consistent again.
What this ranking does not tell you
Typical values and rents describe a city as a whole, not a specific property. A high yield can reflect weak demand, older housing, high vacancy, population loss or higher crime. Appreciation, local landlord laws and property condition are not included. Use the ranking to decide where to research, then analyze real listings.
