Jefferson County is a rent-and-flood diligence case rather than an appreciation-led acquisition: investors who need dependable current income or resale support should be cautious. Zillow’s county median home value was $117,127 in 2026-06, down 2.45% year over year. FHFA’s 2025 repeat-transaction index instead rose 1.92% annually and 49.16% over five years. The methods and vintages cannot be merged; together they leave current value direction unresolved and require comp-level confirmation.
Income underwriting is the central gap. No market asking rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $973 per month is a payment standard, not a market-rent estimate, and cannot fill that gap. The effective property-tax rate is 0.96%, with $1,009 median annual tax; these are carrying-cost inputs, but they do not establish an individual property’s assessment or tax bill. Verify lease comps, utilities, assessments, and insurance before setting NOI.
In the Realtor.com 2026-06 listing market, 29 active listings and 66 median days on market describe visible supply and marketing time, not closed-sale pricing or standalone buyer demand. The 12.82% price-reduced share indicates some seller concessions. Net migration was negative 35 tax-return households, although inbound movers reported average AGI $2,401 above outbound movers. Investors accounted for 3% of 100 purchase mortgages, a limited competing-buyer presence in this measure. The 2025 QCEW data show nearly flat covered workplace employment and higher wages, with Manufacturing the largest disclosed private supersector; this is not resident employment or a demand forecast.
The modeled annual building-value loss ratio is 0.10%, tied to inland flood as the dominant hazard; it is a modeled ratio rather than site exposure or an insurance quote. County evidence cannot resolve elevation, flood zone, prior claims, rebuild cost, or policy availability. Next checks are property-specific flood-insurance terms, rent rolls and lease comps, inspection and capital needs, tax assessment, and closed-sale comps. Those missing items prevent defensible NOI, yield, and resale underwriting.
