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

Day County presents a decision tension: measured home-value momentum is visible, but rental cash flow is not measured and local demand must be underwritten carefully. Yield-focused buyers should investigate rent and expenses before pricing an offer; buyers depending on appreciation or resale liquidity should be cautious. Zillow’s county median home value was $268,945 in 2026-06, up 3.65% year over year. FHFA’s 2025 repeat-transaction HPI showed a 70.92% cumulative five-year increase. That confirms a longer-run direction through a different method, but it is not a dollar value and cannot be blended with Zillow’s change.

02Housing economics

Housing economics remain incomplete. Market rent is not published, so gross yield cannot be computed. The $929 HUD two-bedroom FMR is a payment standard, not an estimate of asking rent, and cannot fill that gap. The effective property-tax rate is 0.98%, a carrying-cost input that needs parcel-level validation. No rent-versus-price or rent-versus-FMR conclusion is supported.

03Demand & competition

Labor evidence is limited but not uniformly weak. QCEW reports 1,966 annual average covered jobs located in the county; Trade, transportation, and utilities is the largest disclosed private supersector, with 500 jobs and 32.57% of private covered employment. This is workplace coverage, not resident employment or unemployment. Net migration was negative 13 tax-return households, while average income of inbound movers exceeded outbound movers by $10,725; neither figure establishes tenant demand. Investors accounted for 9 of 42 purchases, or 21.43%, indicating non-owner participation but not total buyer demand.

04Risk & next checks

Risk limits constrain any county-level thesis. Inland flood is the dominant hazard, and modeled expected annual climate loss equals 0.10% of building value; it is not an insurance quote or a parcel loss estimate. Realtor.com MLS listing price, active listings, days on market, and price-reduction data are not published, preventing a current assessment of asking prices, visible supply, marketing time, or seller concessions. Next checks are property-specific market rent, operating costs, flood zone and insurance terms, plus listing and closed-sale comparables; without them, cash-flow, liquidity, and hazard-adjusted underwriting remain unresolved.

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. Market rent, vacancy, and operating-cost evidence are not published, so a property could fail cash-flow underwriting despite county value momentum.
  2. Flood-zone exposure, elevation, and insurance terms vary by parcel, so the county climate model may not represent an individual asset.
  3. County migration, QCEW, and investor-purchase measures may not translate into demand for a specific unit or submarket.
