Montgomery County Conventional Mortgage Overview

In Montgomery County, the typical conventional loan buyer puts down 26.60%, reflecting strong credit profiles and equity. With a property value averaging $877,797, this down payment avoids Private Mortgage Insurance (PMI), as it exceeds the 20% threshold. The resulting 73.40% loan-to-value (LTV) ratio means these homeowners already hold significant equity, and they can cancel PMI immediately—no waiting period required. The effective property tax rate of 0.85% adds roughly $622 monthly to true affordability, and the recent 0.6% inflation-adjusted increase further nudges costs upward. All 100% of purchases here are for primary residences, indicating a stable, owner-occupied market rather than speculative investment.
