Washington County Conventional Mortgage Overview

For Washington County conventional buyers, the 30.14% average down payment signals strong borrower equity and creditworthiness, typically eliminating the need for Private Mortgage Insurance (PMI) from the start. With a median loan-to-value (LTV) of 69.86%, these owner-occupants already possess over 30% equity, far exceeding the 20% threshold required to cancel PMI. The effective property tax rate of 0.47% translates to roughly $167 monthly on a $426,331 home, while the 1.1% inflation-adjusted tax shift adds minimal pressure to monthly affordability. When evaluating a conventional mortgage with taxes in Washington County, ID, this low tax burden combined with a substantial down payment keeps true housing costs stable.
