Closing costs generally range from 3 percent to 6 percent of the amount of the mortgage. So, if you were to buy a $100,000 house with a 5 percent ($5,000) down payment, you could expect to pay between $2,850 and $5,700 on your $95,000 mortgage. Sometimes, you can negotiate with the seller of a property to pay some of your closing costs, which will reduce the amount of money you will need to bring to closing.
