Methodology
The rate shown is the national 30-year fixed average from the Freddie Mac Primary Mortgage Market Survey, retrieved through FRED. No state-level mortgage survey is published, so we do not invent one.
Local context comes from the Census American Community Survey: South Carolina's median home value, median household income and median real estate taxes paid.
The monthly payment is principal and interest on 80% of the median home value at the national survey rate, over 30 years. It excludes insurance, HOA fees and mortgage insurance.
