Mason County’s decision tension is an apparent Zillow value increase versus a slightly declining FHFA annual HPI, so acquirers need transaction-level verification before setting a basis. Zillow’s June 2026 median home value is $97,343, up 13.02% year over year, while FHFA’s 2025 repeat-transaction HPI declined 0.11% annually. These are differently dated series, and the HPI is not a home value. Closed-sale comparables and property condition are needed before either series can support a valuation conclusion.
Cash-flow underwriting is constrained because market rent is not published; gross yield therefore cannot be computed. HUD’s two-bedroom FMR of $916 per month is a payment standard, not an asking-rent estimate. The 2.09% effective property-tax rate should be tested against the target parcel’s assessment, exemptions, and tax bill rather than netted against unavailable rent. Inland flood is the dominant hazard, and modeled climate loss equals 0.17% of building value per year. That model is not a property-level flood determination or insurance quote.
Demand evidence is mixed. In 2025, QCEW recorded 2,830 annual-average covered jobs at county workplaces; this is not resident employment or a forecast. Trade, transportation, and utilities was the largest disclosed private supersector, not the whole economy. Tax-return migration was net negative by 74 households, while incoming movers’ average AGI exceeded departing movers’ by $3,906. Investor purchases represented 7.81% of 128 purchases. Realtor.com’s June 2026 MLS evidence shows active listings rose 28.21%; its reported price-reduced share is a seller-concession measure, not proof of buyer demand or a closed-sale price.
County-level evidence cannot establish a target property’s rent, condition, flood exposure, insurance cost, assessment, or closed-sale value. Next checks are market-rent and lease comparables with vacancy and operating history; closed-sale comparables; parcel flood maps and insurance quotes; and the assessed value and tax bill. Without them, a gross-yield, net-cash-flow, and property-specific risk conclusion cannot be reached.
