Do two methods point the same way?

Zillow estimates a current home value. FHFA tracks repeat mortgage transactions. Their growth rates should be read side by side, not averaged.

County brief

What the local evidence says

01Decision frame

Knox County is a verification case rather than a clear directional call. Zillow’s June 2026 county median home value is $449,601, down 1.35% year over year, while FHFA’s 2025 annual repeat-transaction HPI increased 3.76%. The observations have different vintages and methods: FHFA’s index is not a home value and should not be combined with Zillow’s change. Buyers setting an acquisition basis should investigate current comparable sales; those relying on continued appreciation should be cautious.

02Housing economics

At the Zillow county observation, median asking rent is $1,742 per month, up 3.47% year over year, and the supplied gross yield is 4.65% before expenses. HUD’s two-bedroom FMR is a payment standard, not an estimate of asking rent, so it cannot replace the measured market rent in a yield calculation. The 1.17% effective property-tax rate is a carrying-cost consideration; county medians do not establish a particular parcel’s tax bill, insurance cost, or net income.

03Demand & competition

Demand and competition evidence is supportive but narrow. Tax-return migration netted 27 households, and the average income of incoming movers exceeded that of outmovers by $22,604; this identifies mover composition, not tenant demand. Among 419 purchases, investors represented 7.64%, indicating some non-occupant mortgage activity but not asset-level bidding pressure. QCEW reports 16,950 annual average covered jobs at county workplaces, up 0.45%; trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy or resident employment.

04Risk & next checks

Hurricane is the dominant hazard, and the modeled annual climate loss ratio is 0.10% of building value; that county-level model does not set a property’s flood, wind, deductible, or insurance exposure. Realtor.com listing price, active-listing, days-on-market, and price-reduction data are not published in this record, preventing a read on visible MLS supply, seller concessions, and marketing time. Property-level insurance, operating expenses, vacancy, condition, and rent comparables are also absent, so net yield and asset-specific liquidity cannot be underwritten.

What can break the county thesis

  1. Property-level hurricane exposure, insurance availability, and deductibles may be materially different from the county modeled loss ratio.
  2. Unpublished MLS supply and concession measures could reveal weaker marketing liquidity than the county record suggests.
  3. Missing operating expenses, vacancy, and unit-level rent comparables may prevent gross yield from converting into sufficient net income.
Underwriting questions

Before pricing a property

Is the reported market rent the same thing as HUD Fair Market Rent?

No. The record identifies market rent as median asking rent, while the HUD two-bedroom FMR is a payment standard rather than an asking-rent estimate.

What does the reported gross yield include?

It reflects annual market rent before costs. The record does not provide enough expense, vacancy, financing, or insurance data to calculate net yield.

Do the QCEW employment figures measure jobs held by county residents?

No. QCEW measures annual average covered employment at workplaces located in the county, not resident employment or unemployment.
