Closing costs can vary from one lender to another. When shopping for a mortgage always look at the total cost of the loan not just the rate. For example Lender A may offer 7% with 1 point and $800.00 in closing costs and Lender B may offer 7% with 1.125 points but only $475.00 in closing costs. On a $100,000 loan Lender B is cheaper but on a $250,000 loan Lender A is cheaper. Typical closing costs by the lender usually include appraisal, credit report, loan processing, and tax service fees. These fees can range between $400.00 and $1200.00. Other fees you may incur are title insurance fees, attorney fees, escrow fees and prepaids. Prepaids usually include fire insurance, property taxes and prepaid interest.
