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

Fremont County’s decision tension is a rising Zillow county home value against unverified rental income and MLS conditions that include concessions. Zillow’s 2026-06 county median home value is $482,700, up 7.43%; FHFA’s 2025 repeat-transaction HPI rose 2.47%. These are distinct vintages and methods: FHFA is an index of repeat transactions, not a dollar home value, and should not be blended with Zillow. Income-focused buyers should be cautious; any buyer relying on appreciation rather than documented cash flow should investigate.

02Housing economics

Housing economics cannot establish cash flow. County market rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $973 per month is a payment standard, not asking rent, and cannot fill that gap. The effective property-tax rate is 0.45%, with median annual tax of $1,398; these are carrying-cost inputs but do not identify a parcel’s bill. Current achievable rent, utilities, insurance and parcel assessment evidence are needed before income can be compared with price and taxes.

03Demand & competition

Realtor.com’s MLS snapshot shows 161 active listings, a 54-day median marketing time, a 19% price-reduced share, and an 18.07% pending-to-active ratio. These are visible asking-market supply, marketing time, and seller concessions, not closed-sale prices or independent proof of buyer demand. Investor participation was 16.56% of 151 purchases, recording a non-occupant slice but not the bid terms or buyer mix on each deal. Net migration was negative 50 tax-return households; movers in reported average AGI $14,895 above movers out, a mixed volume-and-income signal.

04Risk & next checks

QCEW’s annual average reports 3,797 covered jobs at county workplaces, up 1.31%; Trade, transportation, and utilities was the largest disclosed private supersector. This is covered workplace employment, not resident employment, unemployment or a forecast. Inland flood is the dominant hazard; modeled annual building-value loss is 0.21%. It does not identify parcel-level exposure. Without closed-sale evidence, entry-price execution cannot be established; without parcel flood and insurance detail, property-level risk costs cannot be determined.

Bear case

What can break the county thesis

  1. Achievable market rent is unpublished, leaving gross yield and cash-flow support untested.
  2. MLS evidence may not translate into closed-sale pricing or liquidity for a specific property.
  3. County-level inland-flood loss modeling may differ materially from parcel exposure and insurance terms.
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 market rent.

What does the two-bedroom HUD FMR represent?

It is a payment standard, not an estimate of county asking rent.

Which hazard requires parcel-specific review?

Inland flood; the supplied climate-loss measure is county-level and does not establish a property’s exposure.
