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

Madison County presents a valuation-versus-liquidity tension: buyers able to complete property-specific rent, tax, and flood diligence should investigate, while those relying on headline appreciation should be cautious. The Zillow county median home value was $755,719, while FHFA’s repeat-transaction HPI annual reading fell 6.37%. The Zillow county observation and FHFA annual observation use different vintages and methods; the HPI is an index rather than a home value, so the measures cannot be averaged or treated as one price trend.

02Housing economics

Housing economics remain unpriced for income underwriting. County market asking rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $1,540 per month is a payment standard, not an estimate of asking rent, and cannot fill that gap. The stated effective property-tax rate is 0.41%; it is a carrying-cost input, but no parcel assessment, tax bill, insurance premium, operating expense, or lease-comp evidence is published in the record. Neither net cash flow nor all-in ownership cost is established.

03Demand & competition

In 2026-06, Realtor.com MLS evidence shows a listing market requiring negotiation and absorption checks: median marketing time was 92 days and 10.25% of listings had price reductions. These are marketing-time and seller-concession indicators, not closed-sale prices or proof of buyer demand. QCEW annual-average covered jobs at county workplaces fell 0.40% to 2,981 in 2025; this is not resident employment or a forecast. Context is mixed: net migration was 45 tax-return households, and inbound movers’ average AGI exceeded outbound movers’ by $16,618. The record counts 14 investor purchases among 132 total purchases, a 10.61% share; this identifies some buyer competition but not investor rents, hold periods, or transaction prices.

04Risk & next checks

Risk review should center on inland flood. The modeled climate loss ratio is 0.19% of building value per year; it is not a parcel-specific damage forecast or insurance quote. Flood-zone, elevation, mitigation, deductible, and insurer-availability evidence is not published, preventing a defensible hazard reserve. Closed-sale comparables and contract terms are also not published in the record, preventing confirmation that MLS conditions translate into executable value.

Listing price is an asking price, not a closed sale. Quality-flagged county rows are withheld instead of displayed.

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. Subject flood insurance, elevation, or mitigation requirements could make county-level hazard evidence insufficient.
  2. Actual market rent and operating expenses may not support carrying costs, leaving cash flow untested.
  3. MLS listing conditions may not translate into closed-sale value or buyer liquidity.
Underwriting questions

Before pricing a property

Can gross yield be calculated from this record?

No. County market rent is not published, and HUD FMR cannot be substituted for asking rent.

What does the QCEW employment measure represent?

It is annual covered employment at workplaces located in the county, not resident employment, unemployment, or a forecast.

What hazard is identified, and is it priced for a specific property?

Inland flood is identified. The climate measure is a county-level modeled building-value loss ratio, not a parcel loss estimate or insurance quote.
