Butler County is a verification case rather than a clean directional call: Zillow’s $184,299 county median home value fell 7.69%, while FHFA’s separate annual repeat-transaction HPI rose 4.07%. These are different methods and observation vintages, not one comparable growth series. Price-sensitive buyers and investors should investigate whether the Zillow decline reflects local stock mix or weakening values; cautious underwriting should not select either measure as a sale-price forecast. FHFA is an index, not a dollar valuation.
Cash-flow underwriting is constrained because county market rent is not published; gross yield therefore cannot be computed. The $866 HUD FMR is a payment standard, not an estimate of asking rent and cannot support a yield calculation. Against the reported value, the 0.58% effective property-tax rate is a carrying-cost input, but it does not replace parcel tax bills, insurance, maintenance or operating costs. Rent comparables are needed before setting income.
Realtor.com’s MLS listing-market evidence points to a thin but slower visible market: 21 active listings, down 12.50%, sat a median 59 days, up 49.04%, and 25.88% had price reductions. Active listings are visible supply; marketing time and reductions indicate listing friction and seller concessions, not closed-sale prices or buyer demand by themselves. Tax-return migration recorded a net loss of 23 households, with inbound mover average AGI $11,310 below outbound mover AGI. Non-occupants accounted for 13.11% of purchase mortgages. QCEW shows 0.38% annual covered-job growth at county workplaces; Manufacturing, the largest disclosed private supersector, represented 40.48% of private covered jobs. Together, these data warrant submarket verification of tenant depth and purchaser competition.
Modeled annual building-value loss is 0.19%, aligned with the stated inland-flood hazard, but it is a county-level expected-loss ratio rather than a parcel event prediction. Next checks are flood-zone and insurance quotes, rent comps and lease terms, parcel tax history, closed-sale comparables, and neighborhood-level tenant and buyer evidence. Their absence prevents a defensible yield, expense, resale-value, or liquidity conclusion.
