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

Clay County presents a low-basis but incomplete income case: Zillow's 2026-06 median home value is $110,745, up 7.22% year over year, while FHFA's 2025 repeat-transaction HPI rose 1.99%. These are different methods and vintages, not a shared growth rate: the value measure and index should not be averaged. This is a verify-first county for buyers who can source local transactions; appreciation-led underwriting warrants caution.

02Housing economics

Income underwriting is constrained: no market asking rent is published, so gross yield cannot be computed. HUD's supplied two-bedroom FMR is $916 per month, but it is a payment standard rather than market rent. The effective property-tax rate is 1.43%, and median annual tax is $1,392; pair those carrying costs with actual lease comparables, insurance, and maintenance before treating the value change as investable economics.

03Demand & competition

Workplace and household flows are mixed. QCEW annual covered employment grew 1.30%, and average weekly covered-worker wage grew 2.46%; Manufacturing accounts for 40.83% of total private covered jobs, signaling concentration rather than an economy-wide measure. Net migration was negative 23 tax-return households, yet movers in had average AGI $1,837 higher than movers out. Investors made 6 of 85 purchases, a limited but measurable buyer cohort. Realtor.com's listing price, active-listing, days-on-market, and reduction figures are not published, preventing a read on visible supply and seller concessions.

04Risk & next checks

Inland flood is the dominant hazard, and modeled annual climate loss equals 0.17% of building value, a carrying-risk input rather than a dollar loss or property-specific damage estimate. The record also lacks closed-sale comparables and property-specific condition data; county evidence cannot establish a building's renovation needs, insurability, or exit price. Obtain current asking and executed rents, lease terms, flood and insurance details, property-level taxes, and MLS history; without them, yield, operating resilience, and sale-liquidity conclusions remain untested.

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. Actual asking and executed rents may not support taxes, insurance, maintenance, and required return thresholds.
  2. Flood exposure, insurance availability, and mitigation needs may differ materially by property.
  3. Missing MLS and closed-sale evidence may conceal supply, concessions, and exit-liquidity conditions.
Underwriting questions

Before pricing a property

Can gross yield be calculated from the record?

No. Market asking rent is not published. The $916 two-bedroom HUD FMR is a payment standard, not market rent.

Do Zillow and FHFA show the same appreciation result?

No. Zillow's 2026-06 median home value changed 7.22% year over year, while FHFA's 2025 repeat-transaction HPI changed 1.99%; the measures and vintages differ.

How large was measured investor participation?

Investors made 6 of 85 purchases, representing a limited measured buyer cohort.
