Knox County is a verification-first acquisition case: Zillow’s 2026-06 county median home value is $212,400 after an 18.94% year-over-year increase, but market rent is not published. This price-income gap prevents a gross-yield calculation and leaves the move difficult to underwrite. Investors requiring demonstrated cash flow should be cautious; investigators of specific homes should first obtain current asking and achieved rents, condition, insurance, and tax records. The decision tension is a strong measured value change without the income evidence needed to test it.
Zillow’s figure is a county median home value, not a closed-sale price. The 0.83% effective property-tax rate and $842 median annual tax identify carrying-cost inputs, but neither establishes the tax bill for a target property. HUD’s $888 two-bedroom Fair Market Rent is a payment standard, not an estimate of asking rent; it cannot be substituted for market rent. No FHFA annual repeat-transaction HPI is published, so it cannot corroborate or challenge Zillow’s direction, and no blended appreciation measure is supportable.
Labor and mover evidence do not supply a demand verdict, but they narrow the questions. In 2025, QCEW reported 874 annual-average covered jobs located at county workplaces, down 2.89%, and an $836 average weekly covered-worker wage. Trade, transportation, and utilities accounted for 35.77% of private covered employment; it is the largest disclosed supersector, not the whole economy. Tax-return movers numbered 53 in and 72 out, for net migration of -19, while incoming households’ average AGI was $46,755 versus $43,722 for outgoing households. Investors made 2 of 19 purchases (10.53%); that small total describes participation, not price-setting power or all buyers.
Inland flood is the dominant hazard; modeled expected annual building-value loss is 0.18%. This is a modeled ratio, not a property-specific loss estimate. Realtor.com MLS listing-market figures for price, active supply, days on market, and price reductions are not published, preventing assessment of visible supply, marketing time, or seller concessions. Next checks are property-level flood zone, claims history, insurance quote, actual rent comparables, lease terms, and tax bill; county-level evidence cannot settle them.
