Linn County’s underwriting tension is a higher Zillow county median home value of $183,292 in 2026-06, up 11.33% year over year, against FHFA repeat-transaction HPI growth of 4.92% in 2025. These are neither a common period nor method: Zillow’s value measure and FHFA’s sales-pair index should not be combined. Buyers relying on appreciation or a quick resale should investigate transaction-level comparables and absorption; the data indicate direction, not an executable exit price.
Housing economics cannot validate acquisition pricing: county market rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $1,358 per month is a payment standard, not asking rent, and cannot substitute for it. The effective property-tax rate is 1.16%, a recurring carrying-cost input, but does not establish total operating cost. Lease comps, paid utilities, vacancy, insurance and repair evidence are needed to test rent coverage.
Realtor.com MLS listing-market evidence is mixed: 70 active listings were 16.67% higher year over year; median marketing time was 69 days, and 22.77% of listings had reductions. That describes visible supply and seller concessions, not closed-sale pricing or buyer demand alone. Tax-return migration was net positive by 37 households, while incoming movers’ average AGI was higher than outgoing movers’. Investors represented 9.17% of 109 purchase mortgages, a measure that excludes unrecorded buyer types. QCEW annual covered workplace employment rose 2.25% over its prior annual average; it is neither resident employment nor a forecast.
Inland flood is the dominant hazard, and modeled expected annual climate loss equals 0.14% of building value; it is not a parcel-specific loss estimate. Underwriters need flood-zone and elevation records, insurance quotes, and claims history before comparing properties. Missing closed-sale prices, market-rent and lease data, vacancy, property condition, and insurance availability prevent a reliable yield, exit-value, or hazard-adjusted cash-flow conclusion from county evidence.
