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

Grant County presents a price-appreciation case without a cash-flow basis. Zillow’s median home value was $246,740 in 2026-06, up 11.65%, while FHFA’s repeat-transaction index rose 5.97% in 2025. These are different measures and source periods, so they should not be averaged. The decision tension is clear: an investor may see supportive appreciation evidence, but the absent rent series prevents an income test. Buyers focused on current yield should investigate first; appreciation-led underwriting should remain cautious.

02Housing economics

Market rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR is $929 per month, but it is a payment standard, not asking rent, and cannot substitute for a measured rent. The effective property-tax rate is 0.91%, with median annual tax of $1,557. That burden must be carried alongside insurance, repairs, vacancy, utilities, financing, and flood coverage, none of which is supplied. Price therefore cannot be reconciled to net cash flow from this record.

03Demand & competition

Demand evidence is mixed. QCEW covered employment fell 2.85% in 2025, while the covered-worker average weekly wage rose 3.63%; this is workplace employment, not resident employment or unemployment. Trade, transportation, and utilities was the largest disclosed private supersector, not the whole economy. Tax-return migration shows more households leaving than entering, and outbound movers’ average income exceeded inbound movers’ average by a calculated $23,799 gap. Purchases totaled 61, with 7 investor purchases, or 11.48%. That share indicates participation, not buyer demand, and the migration-income pattern does not establish tenant quality or resale depth.

04Risk & next checks

Inland flood is the dominant hazard, while modeled annual building-value loss is 0.14%; that model is not a quote for a particular property. Next checks are parcel flood-zone and elevation, insurance and claims, drainage, deductibles, closed-sale comps, actual rents, lease-up, vacancy, condition, and financing. Realtor.com listing-market evidence is not supplied, so asking-price, visible-supply, marketing-time, and seller-concession signals cannot be assessed. The record’s missing market-rent evidence is the specific gap that prevents yield and cash-flow conclusions; it also leaves the price-to-income relationship 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. Absent market-rent and operating-cost data could make the price unable to support income underwriting.
  2. Declining covered employment and negative net migration could weaken the local-demand evidence used in underwriting.
  3. Inland-flood insurance, claims, elevation, or mitigation findings could make property-level carrying costs differ from the modeled loss ratio.
Underwriting questions

Before pricing a property

Can gross yield be computed from this record?

No. Market rent is not published; HUD FMR is a payment standard rather than market asking rent.

What does the employment evidence measure?

QCEW is annual average covered jobs located in the county, and the named industry is the largest disclosed private supersector, not the whole economy.

What is the recorded investor-purchase signal?

Investor purchases were a minority of total purchases, and the record does not treat that participation as proof of demand.
