Washington County presents a split-signal, low-basis underwriting question: buyers willing to verify property-specific rents and flood costs can investigate, while cash-flow buyers should be cautious. Zillow’s county median home value was $59,610 in 2026-06, down 13.2% year over year, whereas FHFA’s repeat-transaction HPI rose 8.15% in annual 2025 data. These are different methods and periods; the HPI is not a home value and neither series resolves the current purchase-price basis.
No county market asking rent is published, so gross yield cannot be computed. HUD’s $842 two-bedroom FMR is a payment standard, not market rent, and cannot fill that gap. The low value basis does not establish carrying-cost coverage: the effective property-tax rate is 0.86% and needs parcel-level confirmation against the assessment, exemptions and tax bill. Without market rents, utilities, insurance, maintenance and vacancy evidence, the rent-to-cost margin cannot be underwritten.
Realtor.com’s 2026-06 MLS evidence shows a 78-day median marketing time, a 13.25% price-reduced share, and a 22.33% pending-to-active ratio. These are listing-market signals—asking-price seller concessions, visible inventory, and pipeline—not sale prices or proof of buyer demand. Tax-return migration recorded a net outflow of 278 households, and movers out had average AGI a calculated $8,865 above movers in; that composition warrants demand diligence, not a population forecast. Investors accounted for 20.77% of 207 purchase mortgages, indicating non-occupant participation and possible buyer competition, but not all transactions or rental demand.
At county workplaces, 2025 QCEW covered employment declined 0.52%; Trade, transportation, and utilities represented 28.39% of disclosed private covered jobs. That is annual workplace employment, not resident employment or unemployment, and concentration needs tenant- and employer-level checks. Inland flood is the dominant hazard, while modeled expected annual building-value loss is 0.17%. Require parcel flood-zone history, insurance terms, condition, lease comps, closed-sale comps and title/assessment review; absent these, neither stabilized cash flow nor resale liquidity can be concluded.
