St. Mary Parish Conventional Mortgage Overview

For conventional buyers in St. Mary Parish, the 21.51% average down payment is a strong indicator of well-qualified borrowers. This substantial equity stake, reflected in the 78.49% median loan-to-value ratio, typically allows buyers to avoid Private Mortgage Insurance (PMI). Since you are purchasing a primary residence, you are already close to the 20% equity threshold needed to formally request PMI cancellation. The effective property tax rate is a low 0.38%, though the recent 2.7% inflation-adjusted increase means monthly escrow payments will rise slightly. When evaluating a conventional mortgage with property taxes in St. Mary Parish, LA, this low tax burden keeps the average payment manageable despite the 7.133% interest rate.
