St. Charles Parish presents a carry-income-versus-demand-resilience tension: Zillow’s 2026-06 median home value of $270,759 against published median asking rent of $1,475 per month supports the supplied 6.54% gross yield before expenses. This warrants investigation by operators able to verify insurance and unit-level costs, while buyers relying on swift resale or untested tenant demand should be cautious. The county figures are broad measures, not a property underwriting.
Price evidence is positive but not interchangeable: Zillow’s value measure gained 1.89% year over year; separately, the 2025 FHFA repeat-transaction index rose 2.99% annually and 22.66% cumulatively over five years. They align on direction but are different vintages and methods, so cannot be averaged into appreciation. HUD’s two-bedroom FMR of $1,331 is a payment standard, not asking rent, and must not replace the measured rent in the yield. A 0.59% effective property-tax rate is a carrying cost to test alongside the gross measure.
Realtor.com’s 2026-06 MLS snapshot shows higher active listings year over year, an 80-day median marketing time, and 18.7% of listings with price reductions. These are visible-supply, marketing-time and seller-concession evidence, respectively; they are neither closed-sale prices nor proof of buyer demand alone. The 2025 QCEW annual average reports county-workplace covered employment down 11.59%, and Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Outmovers exceeded inmovers and had higher average income, adding a household-demand caution.
Non-occupant purchase mortgages were a minority of total purchase mortgages, so investor activity alone does not establish bidding pressure. The modeled climate-loss measure must be read with hurricane exposure and resolved property by property, not translated into a dollar loss. Missing insurance quotes, flood elevation and claims history, vacancy, unit condition and operating costs, closed-sale comparables, and financing terms prevent a net-cash-flow, resale-liquidity or property-specific hazard-cost conclusion.
