That is a bad situation the lender wants to avoid, so they have historically required cash down payments of 20 percent of a home’s purchase price.
However, if you purchase private mortgage insurance, the down payment requirement can drop to 5 percent or 10 percent of the purchase price.
Few lenders will lend the full value of a home unless they have special guarantees, such as that offered by the Veterans Administration (VA) under its mortgage assistance program.
