Calculator Definitions

•  Home price: The home price is the purchase price you have agreed to with the home seller, which may be different from the listing price or your initial offer.

•  Down payment: The down payment is the amount the homebuyer pays upfront, often expressed as a percentage of the total purchase price. Most buyers put down between 3% and 20%. A 20% down payment is usually required to avoid paying for private mortgage insurance (PMI).

•  Loan term: The loan term is the length of time you have to repay the home loan, usually from 10 to 30 years. A longer term results in lower monthly payments but higher total interest paid over the life of the loan.

•  Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. Your interest rate will be determined by your credit score and type of mortgage loan, among other factors.

•  Annual property tax: The annual property tax is a crucial factor in your total monthly mortgage payment. Many Summerville residents reside in Dorchester County, where the tax rate is .5808%. But some will reside in other counties. For the most precise estimate, search the property ZIP code and “effective property tax rate.”

•  Total monthly payment: The total monthly payment includes the principal and interest. This calculator also includes property tax. It’s essential to understand these components to accurately assess your affordability.

•  Total interest paid: The total interest paid is the amount of interest you will pay over the life of the loan. This figure can be significantly reduced by choosing a shorter loan term.

•  Total loan cost: The total loan cost is the all-in amount you will pay for the loan, including principal and interest.
