Washington County’s underwriting tension is a modest gross yield against slipping price, rent and workplace indicators, while visible listings show concessions rather than a clean demand signal. Income-oriented buyers should investigate property-level costs and tenant depth; buyers relying on appreciation or quick resale should be cautious. This is county evidence, not a conclusion about the Portland metro.
At Zillow’s county 2026-06 observation, the median home value was $568,575, down 2.71% year over year, and median asking rent was $1,911 per month, down 1.18%. That measured market rent produces the supplied 4.03% gross yield before costs; it is not based on HUD. HUD’s two-bedroom FMR is a payment standard, not asking rent. The 0.84% effective property-tax rate is a recurring carrying-cost check. FHFA’s 2025 repeat-transaction HPI fell 0.54% annually but remained 32.78% higher over five years; it corroborates the softening direction but cannot be averaged with Zillow because their vintages and methods differ.
Realtor.com’s 2026-06 MLS evidence has median listing prices down 5.03%, with 27.14% of listings reduced: these are asking-price and seller-concession measures, not sales proof. Active listings were lower, a visible-supply measure, and marketing time was unchanged. QCEW’s 2025 county-workplace employment declined 2.08%; it is covered employment, not resident jobs or unemployment. Migration was net negative by 1,385 tax-return households, and inbound movers’ average AGI trailed outbound movers’ by $7,796. Investors accounted for 304 of 6,383 purchase mortgages, limiting their presence in the recorded purchase flow.
Earthquake is the named dominant hazard, and modeled annual climate loss equals 0.16% of building value; this is neither a site-specific insurance quote nor an expected dollar loss. Missing vacancy, operating expenses, insurance and deductible terms, financing, rent-roll and submarket comparables, sale transactions, tenant incomes, and earthquake engineering evidence prevent net-yield, debt-service, replacement-cost, and exit-price conclusions. Asset-level checks of those gaps are required before county gross yield can be applied to a property.
