Mortgage Insurance (MI)
Insurance that covers the lender against some of the losses incurred as a result of a default on a home loan.

Mortgage insurance is usually required in one form or another on all loans that have a loan-to-value higher than eighty percent. Mortgages above 80% LTV that call themselves "No MI" are usually a made at a higher interest rate. Instead of the borrower paying the mortgage insurance premiums directly, they pay a higher interest rate to the lender, which then pays the mortgage insurance themselves. Also, FHA loans and certain first-time home buyer programs require mortgage insurance regardless of the loan-to-value.
