The median home price in Columbia is $255,000, with a local 30-year mortgage rate of 6.9%. A buyer putting 20% down carries a loan of $204,000, generating a monthly P&I payment of $1,344. Adding property taxes ($119/mo) and homeowners insurance ($106/mo) brings total monthly PITI to $1,569.
Columbia's property tax rate of 0.56% is among the lower rates in the country, which improves overall affordability by keeping total PITI closer to the principal and interest payment alone. On the Columbia median home, that is $119/month, or $1,428 per year.
South Carolina levies a state income tax, which affects take-home pay and effective buying power. High-income earners in Columbia should factor state tax liability into their overall housing budget — mortgage interest may be deductible on both federal and state returns.
