St. Mary Parish presents a cash-flow-versus-price-resilience tension. At Zillow’s supplied 2026-06 county reading, the median home value was $116,261, down 7.78% year over year; FHFA’s separate 2025 repeat-transaction HPI fell 4.09%. These are different methods and vintages, so they cannot be averaged, yet both indicate recent price weakness. Operators who can verify property-level rent durability and expenses should investigate; buyers depending on appreciation, quick resale, or thin reserves should be cautious.
Published median asking rent of $950 per month supports the stated 9.81% gross yield before operating costs. HUD’s two-bedroom FMR of $947 is a payment standard, not an estimate of asking rent, and its proximity does not validate achieved rent or yield. The effective property-tax rate is 0.39%, a carrying-cost input alongside rent rather than a measure of affordability. Hurricane is the dominant hazard, and modeled annual building-value loss is 0.42%; insurance premiums, deductibles, elevation, and property condition are not published, preventing an all-in cash-flow test.
Realtor.com MLS evidence shows a higher median listing price than a year earlier while marketing time lengthened and 24.15% of listings took price reductions. This is asking-price, visible-supply, marketing-time, and seller-concession evidence—not closed-sale pricing or standalone proof of buyer demand. Its active inventory needs submarket and condition checks. Tax-return migration was negative 303 households, and movers arriving had average AGI $2,693 below those leaving, a calculation from supplied incomes. That combination narrows the tenant and owner demand case until local household, vacancy, and absorption evidence is obtained.
Investor purchases numbered 16 out of 220, or 7.27%, so non-owner participation exists but is not enough alone to establish investor demand. QCEW reports declining annual average covered jobs at county workplaces, while covered-worker wages rose; Trade, transportation, and utilities is the largest disclosed private supersector, not the entire economy or resident labor market. Missing lease renewals, vacancy, collections, insurance quotes, concessions, financing terms, and parcel-level taxes prevent conclusions on net yield, exit value, or disaster-adjusted coverage. Next checks are rent rolls, flood and wind insurance, and employment dependence by employer.
