Mason County presents a valuation-versus-income tension: Zillow’s county observation for 2026-06 places median home value at $271,781, up 7.58%. FHFA’s annual 2025 repeat-transaction HPI rose 1.70%. These are different dates and methods, not a common growth interval, and the slower index movement warrants transaction-level valuation checks before treating Zillow appreciation as durable. Investors requiring current income evidence should be cautious.
Income underwriting is constrained because market rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $1,026 per month is a payment standard, not asking rent, and cannot substitute for market rent. Carrying costs need testing against actual lease evidence: the effective property-tax rate is 1.06%, and median annual tax is $2,334. Lease comps, vacancy, operating expenses, and insurance costs are not published, preventing a cash-flow conclusion.
Realtor.com’s 2026-06 MLS listing market is mixed: median days on market was 36, down 27.50%, while 26.18% of active listings had price reductions. Its pending-to-active ratio was 36.57%; these are listing-market measures, not closed prices or proof of buyer demand by themselves. Investor mortgages accounted for 12 of 230 purchases, or 5.22%, a limited but observable competitor share. Tax-return migration was net positive, and average income of incoming movers exceeded that of outgoing movers. QCEW’s 2025 annual average recorded 10,162 covered jobs at county workplaces, down 0.24%; Trade, transportation, and utilities was the largest disclosed private supersector, not a measure of the whole economy.
Inland flood is the dominant hazard, and the modeled climate-loss ratio is 0.06% of building value annually. That county model neither establishes parcel exposure nor insurance terms. Next checks are property-level flood maps, elevation and insurance quotes, lease and vacancy comps, and closed-sale comparables; without them, this record cannot test resilient cash flow, replacement costs, or realized buyer depth. County aggregates also cannot resolve neighborhood, asset-condition, or financing differences.
