Knox County presents a selective underwriting question: Zillow’s county median home value is $83,439, up 1.37%, yet the available evidence does not establish durable cash flow or deep transaction liquidity. Cash-flow underwriters and buyers considering flood-exposed homes should investigate rather than treat the price change as validation; Zillow is a home-value estimate, not a closed-sale series.
Measured market asking rent is not published, so gross yield cannot be computed. HUD’s FMR of $973 per month is a payment standard, not market rent, and cannot substitute in a yield calculation. The effective property-tax rate is 1.60%; it is a carrying-cost input alongside purchase basis, rather than evidence that the reported value is affordable. Obtain current rent rolls, achieved rents, insurance, and tax bills before comparing income with price.
Realtor.com MLS evidence shows constrained visible supply but unproven buyer strength: 14 active listings were down 52.63%, median marketing time was 71 days, 11.11% had reductions, and the pending-to-active ratio was 29.63%. These are asking-price, visible-supply, and marketing measures—not closed sales or standalone proof of demand. QCEW workplace employment grew 2.75%, while average weekly covered-worker wage fell 1.41%. Trade, transportation, and utilities accounted for 40.20% of disclosed private covered jobs, concentrating the labor picture. Migration was net negative, although inbound movers had higher average income than outbound movers. Reported investor participation was 0% across 20 purchases, providing little observed investor activity but a very small purchase base.
Inland flood is the dominant hazard, and the modeled annual building-value loss ratio is 0.13%; it requires parcel-level flood-zone, elevation, drainage, deductible, and insurance-availability review rather than a countywide pricing adjustment. No FHFA annual repeat-transaction HPI is supplied, so Zillow’s direction lacks an independent appreciation-index check. Missing achieved rents, closed-sale comps, vacancy, insurance quotes, and property-specific condition prevent a defensible yield, exit-price, operating-cost, or flood-resilience conclusion.
