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

Elmore County’s decision tension is a measurable pre-cost rent return against potentially softening transaction and labor signals. Zillow’s median home value of $360,993 and median market asking rent of $1,565 per month support the supplied 5.2% gross yield before costs. Asking rent rose 6.15% year over year, while Zillow value also rose. That spread warrants a property-level test of expenses, leaseability and replacement demand rather than treating county appreciation as settled.

02Housing economics

Carrying costs are the constraint on that yield. The effective property-tax rate is 0.54%, yet the record does not publish unit-level operating costs or insurance terms. HUD’s $1,192 FMR is a payment standard, not an estimate of asking rent, and must not replace the market-rent input. FHFA’s annual repeat-transaction HPI rose 9.53% year over year and 68.72% cumulatively. It directionally supports price appreciation, but its distinct supplied period and method cannot be combined with the Zillow county value change into one growth rate.

03Demand & competition

Realtor.com’s MLS listing-market evidence is mixed: median marketing time is 53 days and 15.74% of listings have price reductions, a seller-concession signal. Its listing-price increase is an asking-price measure, not a closed-sale price; slightly higher active listings are visible supply, not proof of buyer demand. Annual QCEW shows a small decline in covered jobs at county workplaces while covered-worker wages rose. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Migration had a net outflow of 126 tax-return households, although the supplied calculation puts incoming movers’ average AGI $2,025 higher. Non-occupant purchase mortgages accounted for 9 of 410 purchases, or 2.2%, limiting evidence of financed investor competition but not identifying cash buyers.

04Risk & next checks

Wildfire is the dominant hazard, and modeled climate loss is 0.35% of building value per year; it does not specify property exposure or insurance cost. No vacancy, lease-renewal, unit-level expense, insurance-quote, or closed-sale-comparable evidence is published in this record. These gaps prevent a net-income estimate, property-specific hazard-cost assessment, and conclusion that MLS asking conditions translate to sale pricing. Cautious buyers should check parcel hazards, insurability, operating statements, lease rolls and closed transactions before relying on gross yield.

Bear case

What can break the county thesis

  1. Unobserved insurance and wildfire-mitigation costs are excluded from the reported pre-cost yield.
  2. Net migration loss and a small decline in QCEW covered jobs leave county-level rental-demand evidence unresolved.
  3. MLS price reductions and marketing time do not establish achieved sale prices or exit liquidity.
Underwriting questions

Before pricing a property

Can gross yield be calculated from the record?

Yes. The record supplies gross yield using median market asking rent and median home value before costs; HUD FMR is not used.

What does the labor evidence measure?

Annual QCEW measures covered jobs at county workplaces and covered-worker wages; it does not measure resident employment or unemployment.

What does the buyer data show about investor competition?

Non-occupant purchase mortgages were limited relative to reported purchases, but the record does not identify cash buyers.
