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

Bonneville County presents a carry-versus-exit tension for rental underwriting. Zillow’s 2026-06 county observation shows a $404,732 median home value, a small year-over-year increase, $1,415 median monthly asking market rent, and a stated 4.2% gross yield before expenses. Buyers relying on appreciation or very thin expense assumptions should be cautious; operators prepared to verify unit economics and flood exposure should investigate. County aggregates do not substitute for property-level underwriting.

02Housing economics

Market asking rent is distinct from HUD’s $1,305 two-bedroom Fair Market Rent payment standard; it is not an asking-rent estimate. The supplied market rent is 8.4% above that standard. The 0.5% effective property-tax rate reduces the stated gross yield before insurance, repairs, vacancy and management. FHFA’s 2025 repeat-transaction HPI also increased, but it is an appreciation index, not a home value; its different supplied period and method cannot be averaged with Zillow’s change.

03Demand & competition

Realtor.com’s MLS evidence has median listing price down 6.17% year over year, active listings falling, median days on market at 51, and 21.23% of listings showing reductions. Those are asking-price, visible-supply and marketing-time signals—not closed sales or stand-alone proof of buyer demand. QCEW shows rising annual covered workplace employment, not resident employment or a forecast. Tax-return migration was net positive by 375 households, while in-movers’ average income was $255 lower than out-movers’. Investor purchases were 6.92% of 1,706 purchases; participation is present but not dominant.

04Risk & next checks

Inland flood is the dominant disclosed hazard, and modeled annual climate loss is 0.15% of building value. That model supports a flood-focused screen but is not a parcel loss estimate. The record does not publish vacancy, operating expenses, insurance quotations, debt terms, property flood-zone or claims history, closed-sale comparables, or unit mix and condition. Their absence prevents a stabilized net-income, debt-coverage, resale-comparability or property-specific hazard conclusion; verify these items alongside tax assessment and lease evidence.

Bear case

What can break the county thesis

  1. Unpublished vacancy and operating costs could materially reduce the stated gross-yield case.
  2. Parcel-specific flood exposure and insurance costs could exceed the county-level climate model.
  3. Listing-market softness could be reflected in weaker closed-sale pricing than the available evidence shows.
Underwriting questions

Before pricing a property

Is market rent published for the county?

Yes. The record publishes median monthly asking market rent and a stated gross yield.

Does HUD Fair Market Rent estimate the county’s asking rent?

No. The record identifies it as a two-bedroom payment standard.

What does the QCEW employment evidence measure?

Annual average covered jobs located at workplaces in the county, not resident employment.
