Lafourche Parish presents a cash-flow-versus-resilience tension: published rent economics sit beside hurricane exposure, soft county migration, and listing concessions. This warrants property-level investigation by buyers who need durable operating income; underwriting that depends on appreciation, quick resale, or generic county averages deserves caution. The evidence is county-level, so it cannot establish performance for a neighborhood, elevation band, property type, or insurance profile.
Zillow’s 2026-06 county median home value is $189,978, down 0.93%, while median asking rent is $1,302 per month; the supplied gross yield is 8.22% before operating costs. The effective property-tax rate is 0.54%, a carrying-cost input rather than a full expense estimate. HUD’s two-bedroom FMR is published as a payment standard, not market asking rent, so it is not used to infer yield. FHFA’s 2025 repeat-transaction HPI increased 0.34%; it is an appreciation index, not a value, and its different vintage and method should not be combined with Zillow’s change.
Realtor.com’s 2026-06 MLS evidence shows 349 active listings and 20.84% with price reductions. Those measures describe visible asking-side supply and seller concessions, not closed prices or proof of buyer demand. Tax-return migration records a net loss of 272 households; average AGI for movers out exceeded movers in by $1,529, adding caution on the composition of moving demand. Non-occupants received 55 of 733 purchase mortgages, indicating some investor participation without showing who won bids or how they perform. QCEW is annual covered employment at county workplaces, not resident employment or a demand forecast; Trade, transportation, and utilities is only the largest disclosed private supersector, not the whole economy.
The dominant hazard is hurricane, and the modeled annual climate-loss ratio is 0.48% of building value. That modeled exposure should be paired with parcel flood, wind, elevation, replacement-cost, deductible, and insurance-availability review; it does not state an owner’s actual loss or premium. Insurance quotes, flood-zone and elevation data, property condition, vacancy and operating expenses, financing terms, sale comparables, and subcounty rent data are not published here. Their absence prevents a net-yield, debt-service, replacement-cost, and exit-price conclusion.
