Knox County is a current-income-versus-durability screen for buyers who can validate unit economics and flood exposure, rather than a broad price-growth call. Zillow's 2026-06 county observation reports a $383,827 median home value and $1,768 monthly median asking rent, producing the supplied 5.53% gross yield before operating costs. This is measured market asking rent; the yield is not net income and cannot establish cash flow without financing, insurance, repairs, vacancy, and property-specific expenses.
HUD's two-bedroom FMR is $1,471 and is a payment standard, not an asking-rent estimate; it must not replace the Zillow rent in underwriting. The effective property-tax rate is 0.43%, a recurring carrying-cost input against the stated gross yield, although parcel variation is not shown. FHFA's 2025 repeat-transaction HPI rose 2.95% in its annual reading. It supports positive indexed appreciation under a different method and vintage, but it is neither a dollar home value nor a rate to average with Zillow's observation.
Realtor.com's MLS listing-market evidence shows 1,679 active listings and 22.78% with price reductions. Those are visible supply and seller-concession signals, not closed-sale prices or independent proof of buyer demand. Net tax-return migration was 1,518 households, while average income of inbound movers exceeded outbound movers by $5,486; that composition is supportive context but does not identify renter demand or neighborhood location. Investor purchases were 657 of 6,720 total purchases, a 9.78% share: a defined competing buyer cohort, not proof of investor dominance. QCEW describes covered jobs at county workplaces and covered-worker wages, not resident employment, tenant income, or a forecast.
Modeled annual climate loss equals 0.11% of building value, and inland flood is the dominant hazard; this is a modeled loss ratio, not a parcel flood determination or a dollar loss. Cautious buyers should obtain parcel flood zone, elevation, insurance quotes, and loss history. Rent roll, vacancy, turnover, operating expenses, financing terms, and closed-sale comparables are not published here; their absence prevents a net-yield, debt-coverage, sale-value, or property-specific flood-cost conclusion.
