Knox County’s decision tension is a rising value signal in a small market against unverified rental income and more tax-return movers leaving than arriving. The Zillow county median home value was $216,318 in 2026-06, up 6.44% year over year, while the FHFA repeat-transaction HPI for 2025 rose 3.32% and was 43.94% higher over five years. Those observations have different methods and labeled periods, so they support positive direction but cannot be combined into one appreciation rate. Investors needing verified operating income should be cautious; asset-level investigators should test whether county-level movement holds for a particular property.
Rental economics are unproved: market rent is not published, so gross yield cannot be computed. HUD’s $961 two-bedroom FMR is a payment standard, not market asking rent, and cannot fill that gap. The effective property-tax rate is 1.15%, and median annual tax is $1,472. Both are carrying-cost inputs, not a subject-home tax bill. Underwriting still needs an actual rent schedule, parcel tax record, insurance quote, and operating-cost history.
Labor and buyer evidence is mixed. QCEW covered workplace employment changed only 0.17% in its annual county record; it is neither resident employment nor unemployment. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Tax-return migration had more households leaving than entering, although incoming movers averaged $58,254 of AGI versus $40,497 for outgoing movers. Investors held 23.53% of purchase mortgages across 34 purchases, a visible competitor group but a thin transaction base for inferring broad buyer demand.
Risk limits are material. Inland flood is the dominant hazard, and modeled annual climate loss equals 0.17% of building value; that model is not a parcel loss estimate. Realtor.com MLS listing-market figures are not published, preventing conclusions about visible supply, marketing time, or seller price reductions. Next checks are property-level flood exposure and insurance, closed-sale comparables, leases and market rents, and title and condition review; without them, neither income coverage nor exit liquidity is established.
