Marin County Conventional Mortgage Overview

In Marin County, the average 34.43% down payment on a Conventional loan significantly exceeds the 20% threshold, allowing buyers to avoid Private Mortgage Insurance (PMI) entirely. This high equity position, reflected in a low 65.57% Loan-to-Value (LTV) ratio, signals strong buyer credit and financial stability for these owner-occupied homes. With the average property value near $1.93 million, the effective 0.77% property tax rate adds roughly $1,235 monthly, a key factor when using a conventional mortgage with taxes analysis. This tax burden, alongside a 6.875% interest rate, defines true affordability for Marin County homebuyers.
