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.
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.
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.
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.
