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 presents a price-versus-underwriting tension: investigate whether rising values are sustainable, but income buyers should remain cautious until operating rent is verified. Zillow’s county median home value was $235,759 in 2026-06, up 4.53% year over year. FHFA’s separately labeled 2025 repeat-transaction HPI is positive and shows a 35.82% cumulative gain over its supplied horizon; it is an index, not a home value. The methods and vintages cannot be averaged or treated as a single growth interval.

02Housing economics

Measured market rent is not published, so gross yield cannot be computed from the record. HUD FMR of $919 per month is a payment standard, not asking rent, and cannot substitute for it. The 1.36% effective property-tax rate is a carrying-cost input alongside purchase price, but the record lacks property-specific tax, insurance, repairs, vacancy, and financing information needed to establish cash flow or a price-to-rent test.

03Demand & competition

Demand evidence is mixed. Annual QCEW covered workplace employment fell 7.26%, while Manufacturing, the largest disclosed private supersector, represented 39.76% of private covered jobs; this is a concentration check, not resident employment or a forecast. Realtor.com’s MLS market showed 50 days median marketing time and 15.06% of listings with price reductions: seller concessions, not closed-sale pricing or buyer demand alone. Tax-return migration had net outflow of 20 households, although arrivals had a positive supplied AGI gap versus departures. Investor participation was 8 of 154 purchases, or 5.19%, a small documented component rather than proof of weak competition for a specific asset.

04Risk & next checks

Inland flood is the dominant hazard, and the modeled annual climate-loss ratio is 0.12% of building value; that is expected loss, not a dollar loss or parcel determination. County-level evidence cannot identify flood zone, insurance premium, mitigation need, condition, or replacement cost. Next checks are address-level flood and insurance records, current lease and asking-rent comparables, operating statements, and recent closed-sale comparables. Without them, the record cannot underwrite net income, capitalization, flood-adjusted carrying cost, or exit value.

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. Property-level market rent, expenses, and financing terms could materially weaken the economics implied by county price data.
  2. Countywide flood-loss modeling may differ from a specific property’s flood exposure, insurance cost, and mitigation requirements.
  3. Covered workplace employment and MLS conditions may not represent the subject property’s tenant base, submarket, or closed-sale outcome.
Underwriting questions

Before pricing a property

Can gross yield be calculated from this record?

No. Measured market rent is not published, and HUD FMR is not a market-rent estimate.

What employment series is supplied?

QCEW annual covered employment at workplaces in Iowa County; it is not resident employment, unemployment, or a forecast.

What does the listing evidence measure?

Realtor.com reports MLS asking-market conditions, including visible listings, marketing time, and price reductions; it does not report closed-sale prices.
