St. Clair County FHA Mortgage Overview

For St. Clair County homebuyers, the 10.30% average down payment on an FHA loan provides accessible entry, but the accompanying 89.70% Loan-to-Value ratio means Mortgage Insurance Premiums (MIP) are required for the life of the loan—ideal for those with sub-620 credit. The 1.83% effective property tax rate, with a recent 0.6% inflation-adjusted increase, adds meaningful monthly cost. When evaluating an FHA mortgage with property taxes, note the property value averages $209,092. This data reflects 100% owner-occupied purchases, not investments.
