If you put less than 20 percent down on a home mortgage, lenders often require you to have Private Mortgage Insurance (PMI). PMI protects the lender if you default on the loan. The Homeowners Protection Act of 1998 - which became effective in 1999 - establishes rules for automatic termination and borrower cancellation of PMI on home mortgages. These protections apply to certain home mortgages signed on or after July 29, 1999 for the purchase, initial construction, or refinance of a single-family home. These protections do not apply to government-insured FHA or VA loans or to loans with lender-paid PMI.
