Closing on a home is the final step in the home purchase process. That last step, however, includes additional expenses, known as closing costs, that buyers and sellers may incur to complete the home purchase process. Home purchasers can understand what those closing costs will be by reading the Good Faith Estimate that lenders are required to provide as part of the loan application process. Closing costs usually cover fees related to the origination and underwriting of a loan, real estate commissions, insurance, property taxes, and transaction recording costs.
