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

Iowa County’s decision tension is rising measured values against unproven property income and carrying costs. Investors able to validate lease comparables and parcel flood exposure should investigate; yield-dependent buyers should be cautious. The Zillow county median home value was $344,898 in 2026-06, a 4.50% year-over-year increase. Separately, FHFA’s repeat-transaction HPI rose 5.14% in 2025 and 58.82% over the supplied five-year measure. Those measures support a positive direction, but the HPI is not a home value and their distinct methods and observation periods cannot be averaged.

02Housing economics

No county market rent is published, so gross yield cannot be computed. The $1,168 two-bedroom HUD FMR is a payment standard, not an estimate of asking rent, and cannot fill that gap. The effective property-tax rate is 1.52%, while median annual tax is $4,038; neither establishes the tax on a specific asset or rent coverage. Realtor.com MLS listing inputs are not published here, preventing assessment of active visible supply, marketing time, or price reductions; those indicators would not by themselves establish closed-sale pricing or buyer demand.

03Demand & competition

Tax-return migration was balanced, with 582 households moving in and the same number moving out; incoming movers’ average income exceeded outgoing movers’ by $8,555. This indicates turnover with a higher reported incoming-income profile, not net migration growth. Investors accounted for 15 of 218 purchase mortgages, or 6.88%, a defined non-occupant-financed slice rather than a measure of all competing buyers. QCEW annual covered workplace employment rose 0.33% over its prior annual average. Trade, transportation, and utilities was the largest disclosed private supersector; QCEW does not measure resident employment, unemployment, or a forecast.

04Risk & next checks

Inland flood is the dominant stated hazard, and the modeled annual building-value loss ratio is 0.11%. This county-level model is not a parcel loss estimate. Missing flood-zone, elevation, drainage, claims, insurance, lease-comparable, and property-specific tax evidence prevents a site-level cash-flow and hazard conclusion. Next checks are achieved market rent, lease terms, current MLS inventory and concessions, and parcel insurance and flood documentation.

Bear case

What can break the county thesis

  1. Achievable rents may not support carrying costs because market rent and lease comparables are absent.
  2. Parcel-level inland-flood exposure and insurance cost may differ materially from the county climate-loss model.
  3. County employment and migration measures may not translate into demand for a specific property, while MLS supply and concession data are unavailable.
Underwriting questions

Before pricing a property

Can gross yield be calculated from the record?

No. County market rent is not published, and HUD two-bedroom FMR is a payment standard rather than market rent.

What does the record show about migration?

It shows equal inflows and outflows of 582 tax-return households, with incoming movers averaging $8,555 more income than outgoing movers.

What is the documented investor purchase-mortgage share?

Investors accounted for 15 of 218 purchase mortgages, or 6.88%.
