Custer County Conventional Mortgage Overview

In Custer County, the typical conventional homebuyer puts down 30.73%, resulting in a low 69.27% loan-to-value ratio. This strong equity position means buyers can immediately avoid Private Mortgage Insurance (PMI). For those exploring a conventional loan with property taxes, the effective 0.71% tax rate is manageable, but a recent 9.6% inflation-adjusted tax increase adds to monthly carrying costs. Given the 100% primary occupancy rate, these are owner-occupied homes. Aspiring buyers using a conventional mortgage with PMI and taxes in Custer County, South Dakota, should note that building 20% equity is already achieved at purchase, eliminating any PMI timeline concerns.
