Jefferson Davis Parish presents a valuation-versus-resilience tension: investors who can verify property-level flood exposure and durable tenant demand should investigate, while yield-led buyers should be cautious. Zillow's county median home value was $153,628 in 2026-06, down 1.78% year over year. FHFA's repeat-transaction HPI, observed in 2025, rose 2.94% annually; that is an index movement rather than a home value and does not share Zillow's time frame or method. The measures point in different directions, so neither establishes a settled county price trend.
Housing economics remain untestable on income return: market rent is not published. HUD FMR of $871 per month is a payment standard, not an asking-rent estimate, so gross yield cannot be computed. The 0.29% effective property-tax rate and $442 median annual bill give an observed tax reference, but neither captures insurance, maintenance, financing nor other operating costs. Underwriting should therefore keep rent, tax, and hazard costs separate.
Demand evidence is mixed. Tax-return household flows show 657 moving in and 757 moving out, for net migration of -100; incoming movers' average AGI exceeded outgoing movers' by $3,341. Annual QCEW workplace covered employment was 7,931, down 1.11%; this is neither resident employment nor an unemployment measure. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Investor non-occupant purchase mortgages were 23 of 219, or 10.5%, indicating a measurable buyer cohort but not its bidding behavior or share of all sales.
Inland flood is the dominant hazard; the modeled climate loss ratio is 0.35% of building value per year, not a property-specific insurance quote or a dollar loss. No Realtor.com MLS listing price, active-listing, days-on-market, or price-reduction measure is published, preventing an assessment of visible supply, marketing time, and seller concessions. Next, obtain property-level flood zone, elevation, insurance, rent-roll, and closed-sale comparable evidence; absent market rent still prevents a gross-yield conclusion.
