Johnson City's decision frame starts with Zillow's typical city home value of $300,337 and typical observed monthly market rent of $1,467. Those inputs imply a 5.9% gross yield—annual ZORI divided by ZHVI—before every operating cost and financing. The value equals 5.25x ACS median household income, while annual ZORI equals 30.8% of that income. This is citywide screening, not a property cash-flow result or proof of tenant affordability.
Citywide, renters occupy 48.7% of occupied units, and the housing-stock vacancy rate is 8.1%. ACS reports a $268,200 median value for surveyed owner-occupied housing and $1,023 median gross rent for occupied rentals, including contract rent and selected utilities. Those ACS measures describe occupied housing and differ in definition and period from Zillow's typical value and observed market rent above; they should not be averaged or treated as direct checks on one another.
Among city renter households, 49.6% are rent-burdened. Single-family units are 58.3% of city housing stock and large multifamily units are 8.6%; neither share measures purchasable inventory. For-rent units account for 27.5% of vacant units, but citywide vacancy reasons do not predict a specific unit's lease-up. Across overlapping ACS vintages, reported city population increased 8.6%, a nonannualized comparison that may reflect boundary changes. Median household income is $57,254, while poverty is 20.3% and unemployment is 5.6%; these are descriptive demand constraints, not causes of future performance.
Wider evidence varies by scope. In Carter County, county listings showed 22.5% with price reductions; in Sullivan County, the county share was 25.0%; in Washington County, the county share was 24.1%. These county records must remain separate because Johnson City crosses their boundaries. The broader Johnson City metro showed 32.4% of listings with price drops and 3.2 months of supply, while Johnson City metro employment was down 0.3%. The national Freddie Mac 30-year mortgage rate was 6.58%, a financing benchmark rather than a city borrowing quote.
Underwriting is limited by citywide typicals, ACS sampling and vintage overlap, and wider geographies that do not measure the city. Gross yield omits operating and capital costs; aggregate tenure, vacancy and burden cannot establish achievable rent or occupancy. Next, verify the parcel's county, asking and signed rent comparables, utility responsibility, tax assessment, insurance and hazard terms, condition, deferred maintenance, management, turnover and lender-specific pricing. Recalculate cash flow from the actual price and lease assumptions, with reserves and scenario tests.
