Learn moreHousing well below the Louisiana statewide median
LaPlace's median sale price ran $184,000 this pass (down 16.4% YoY), with a separately tracked $235,000 median active-listing price as of May 2026 -- both well below Louisiana's own $260,300 statewide median sale price.
A property tax rate below Louisiana's already-low statewide cluster
St. John the Baptist Parish's effective property tax rate ran approximately 0.45% this pass -- below even Louisiana's own already-low statewide 0.52%-0.55% cluster -- with a median annual tax bill of just $877.
Louisiana's flat 3% income tax and 10.11% combined sales tax apply regardless
Louisiana's real, flat 3% state income tax (effective Jan. 1, 2025) and 5% base state sales tax (10.11% average combined state-and-local, the nation's highest per the Tax Foundation) both apply in LaPlace exactly as they do statewide.
A real, documented 2023 insurance rate spike
St. John the Baptist Parish homeowners saw a documented 111% Citizens Property Insurance rate increase in 2023, in Hurricane Ida's direct aftermath -- a real, dated cost factor genuinely more severe than Louisiana's statewide insurance trend alone suggests.
