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’s decision tension is a lower entry-value signal against a positive repeat-transaction index, with no published market rent to show whether either supports income. Zillow’s 2026-06 county median home value is $140,268, down 6.82% year over year, while FHFA’s annual 2025 repeat-transaction HPI rose 3.12%. These different vintages and methods cannot be averaged into one growth view; the HPI is not a home value. Investigate property condition and recent closed comparables before treating the Zillow decline as bargain entry; cautious buyers lack an income cross-check.

02Housing economics

Housing economics remain unproven. Market asking rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR is $866 per month, but it is a payment standard rather than an estimate of asking rent and cannot substitute for rent in underwriting. The effective property-tax rate is 0.66%; it belongs in carrying-cost review but does not establish operating cost or rent coverage. Obtain asking and achieved rents, lease-up, insurance, maintenance, and parcel tax bills; without them, price-to-rent and net-cash-flow tests are prevented.

03Demand & competition

Demand evidence is mixed and limited to QCEW workplaces and tax-return movers. The QCEW annual county series reports 7,528 covered jobs at workplaces in the county, down 2.04%, and a $878 average weekly covered-worker wage. Education and health services, the largest disclosed private supersector, accounts for 33.57% of private covered employment, not the whole economy. Migration was net positive by 10 tax-return households, but incoming average AGI trailed outgoing AGI by $74. Investor share was 3.87% of 181 purchase mortgages; this reflects non-occupant mortgage participation, not cash activity or all buyer competition.

04Risk & next checks

Inland flood is the dominant hazard, and the modeled climate-loss ratio is 0.26% of building value per year; it is a modeled loss ratio, not a parcel-specific insurance quote. Realtor.com listing figures are not published in this record, so no MLS asking-price, active-supply, marketing-time, or price-reduction conclusion can be made; even if available, they would be listing-market rather than closed-sale evidence. Next checks are flood-zone and claims history, insurance quotes and elevation/mitigation, recent closed comparables, parcel taxes, and market rent and vacancy evidence. These gaps prevent a defensible yield, liquidity, and hazard-adjusted carrying-cost conclusion.

No rent index is published for this county.Zillow’s county rent series does not cover every county, and estimating one from a neighbouring county would be a guess wearing a number’s clothes. Everything above is measured here; no wider market is mapped for it either.
Bear case

What can break the county thesis

  1. Zillow’s current value direction and FHFA’s transaction-index trend use different timing and methods, so neither may represent the subject property.
  2. Missing market rent, vacancy, and operating-cost evidence could overturn any yield or cash-flow assumption.
  3. Parcel flood exposure and insurance costs may differ materially from the county-level modeled loss ratio.
Underwriting questions

Before pricing a property

Can gross yield be calculated from this record?

No. Market asking rent is not published, and HUD’s two-bedroom FMR is a payment standard rather than market rent.

What investor mortgage participation is reported?

Investor share is 3.87% of 181 purchase mortgages, representing non-occupant mortgage purchases rather than all buyer activity.

What hazard-loss measure is provided?

Inland flood is the dominant hazard, with a modeled climate-loss ratio of 0.26% of building value per year.
