Lavaca County is a verification case for buyers able to underwrite property-level rent and insurance, and a caution case for anyone relying on appreciation. Zillow’s $298,952 county median home value at 2026-06 increased year over year, while FHFA’s repeat-transaction HPI rose 8.08% in its separately labeled 2025 annual observation. Both point upward, but their differing vintages and methods cannot be merged: FHFA is an index, not a dollar value. The tension is positive price direction beside listing-market friction and absent market-rent evidence.
No county median asking rent is published, so gross yield cannot be computed. HUD’s $1,055 two-bedroom FMR is a payment standard, not a market-rent estimate, and cannot fill that gap. Carrying-cost review should start with the 0.89% effective property-tax rate and $2,041 median annual tax, then use parcel assessments rather than applying a county median tax to an individual home. Price, unobserved rent and tax burden therefore do not establish cash-flow coverage.
Realtor.com offers MLS listing-market evidence, not sale-price confirmation: it recorded 65 active listings in 2026-06, a 113-day median marketing time, 17.06% reduced, and a 22.48% pending-to-active ratio. This combination calls for offer-level closed comps and absorption review; active supply or pendings alone do not prove buyer demand. QCEW reports an annual decline in covered jobs at county workplaces, not resident employment or unemployment. Net migration was negative, although incoming movers had higher average AGI than outgoing movers, leaving household-count and income signals mixed. Investors accounted for 15 of 141 purchase mortgages, or 10.64%, a visible but limited buyer segment rather than proof of pricing power.
Risk screening must center on inland flood: modeled climate loss equals 0.17% of building value per year, an expected-loss ratio rather than a property-specific insurance quote. Missing flood-zone, elevation, prior-loss, premium and deductible data prevent a net-carrying-cost conclusion. Missing closed-sale prices, property-level rent, vacancy, operating expenses, financing terms and resident income also prevent valuation, yield and affordability conclusions. Next checks are parcel flood and insurance records, rent comps and lease-up history, closed comps, and local assessment details.
