Local Market Insights

Carter County Conventional Mortgage Overview

In Carter County, the 38.03% average down payment on a Conventional loan reflects strong buyer equity and creditworthiness. This substantial down payment typically eliminates the need for Private Mortgage Insurance (PMI), as borrowers start with a 61.97% Loan-to-Value (LTV) ratio—well below the 80% threshold required to cancel PMI. For those using a conventional mortgage with property taxes, the 0.20% effective tax rate is low, but the recent 12.1% inflation-adjusted tax increase will meaningfully raise monthly carrying costs on a $325,000 property. All buyers here are purchasing primary residences, indicating a stable, owner-occupied market rather than speculative investment activity.
