Cowlitz County presents an income-versus-carrying-cost tension for an investor who can verify a specific asset, while buyers relying on broad county appreciation evidence should be cautious. The supplied county median home value is $424,037 and median asking market rent is $1,374 per month, producing the stated 3.89% gross yield before costs. Zillow’s value measure was essentially flat, whereas FHFA’s repeat-transaction HPI rose 3.72%. That FHFA result is an index change, not a home value; its method and observation vintage differ from Zillow’s, so the figures cannot form a single appreciation rate.
Housing economics are constrained by the distinction between rent and assistance standards. HUD’s two-bedroom FMR is $1,451 per month, a payment standard rather than asking rent; supplied market rent is 94.7% of it. The gross yield uses market asking rent, not FMR. The effective property-tax rate is 0.82%, a carrying cost that needs parcel-level confirmation alongside insurance and operating expenses. No net yield or cash flow can be calculated from the published record.
Realtor.com supplies MLS listing-market evidence: 372 active listings represent visible supply, while 44 median days on market and a 31.07% price-reduced share describe marketing time and seller concessions. They are neither closed-sale prices nor proof of buyer demand. Net migration was 241 tax-return households; incoming movers had an average AGI advantage of $8,006, a calculation from the supplied mover averages. Investor purchase mortgages were 3.89% of 1,337 total purchases, a defined non-occupant mortgage measure that does not by itself establish broad buyer competition.
Inland flood is the dominant hazard, and modeled expected annual building-value loss is 0.28%; this is not a dollar loss estimate for a particular property. Annual QCEW covered workplace employment fell 0.31%; it is not resident employment or an economic forecast. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Property-level flood zone, insurance quotes, unit condition, operating costs, vacancy, lease renewals and closed-sale evidence are not published; their absence prevents net-income, insurability and resale underwriting.
