In the event that you do not have a 20 percent down payments, lenders will allow a smaller down payment, as low as 5 percent in some cases. With the smaller down payments loans, however, borrowers are usually required to carry private mortgage insurance. Private mortgage insurance will require an initial premium payment of 1.0 percent to 5.0 percent of your mortgage amount and may require an additional monthly fee depending on your loan’s structure. On a $75,000 house with a 10 percent down payments, this would mean either an initial premium payment of $2,025 to $3,375, or an initial premium of $675 to $1,130 combined with a monthly payment of $25 to $30.
