Jefferson County presents a price-versus-income tension for underwriting. Zillow’s 2026-06 record puts the median home value at $628,821, down 2.2% year over year, while median asking rent is $1,981 and gross yield is 3.78% before costs. FHFA’s 2025 repeat-transaction HPI rose 0.48% year over year and reports a separate 40.55% cumulative five-year increase, not annualized. Those vintages and methods cannot be averaged. The thesis is a capital-intensive, thin-current-income case with conflicting appreciation signals. Yield-focused buyers should be cautious; appreciation-focused buyers should investigate the specific asset rather than rely on a county series.
Market rent, not HUD FMR, should anchor the rent line: it is 94.8% of the HUD two-bedroom standard of $2,089. FMR is a payment standard, not an asking-rent estimate. The effective property-tax rate is 0.48%, with median annual tax of $3,082. Inland flood is the dominant hazard; modeled annual building-value loss is 0.20%. Insurance premiums, vacancy, repairs, utilities, management and financing are not published, so the supplied gross yield cannot become a net yield or cash-flow conclusion.
Demand and competition are mixed. Realtor.com’s 2026-06 snapshot records 2,101 active listings; that is visible MLS supply, not closed-sale demand evidence. QCEW’s 2025 annual record shows covered employment down 0.36% while the covered-worker average weekly wage rose 5.95%; these are workplace jobs, not resident employment or unemployment. Net migration is positive, but average mover AGI is nearly aligned inbound and outbound, weakening the income signal from flow alone. Investor mortgages are 6.75% of 7,122 total purchases: participation is material but not dominant, and it does not prove competition.
Next checks are property-level: closed-sale and lease comps, flood-zone and elevation review, an insurance quote, and a full operating and financing budget. Closed-sale evidence is needed to decide whether Zillow’s decline, Realtor asking-price conditions, or FHFA’s repeat-transaction gain describes the target; these series do not answer that question. Missing expense and insurance data prevent a net-return decision, while missing resident employment, vacancy and tenant-quality evidence prevent a tenant-demand conclusion. Separate county signals from parcel facts.
