San Juan County Conventional Mortgage Overview

In San Juan County, a 36.47% down payment on a Conventional loan is significantly above the national median, reflecting strong buyer equity and credit profiles. This high down payment immediately eliminates the need for Private Mortgage Insurance (PMI), as buyers surpass the 20% equity threshold at closing. The low 63.53% Loan-to-Value (LTV) ratio further reduces lender risk for primary residences. With an effective property tax rate of 0.53% and a slight inflation-adjusted decrease of -0.1%, monthly affordability remains stable. For those evaluating a Conventional loan with property taxes in San Juan County, WA, this data suggests a premium market where substantial upfront capital reduces long-term carrying costs.
