Definition
The mortgage insurance charged on FHA loans: an upfront premium (a small percentage of the loan, usually rolled into the balance) plus an annual premium paid monthly. Unlike PMI on conventional loans, MIP on a low-down-payment FHA loan generally lasts the life of the loan; the usual exit is refinancing into a conventional loan after building 20% equity.
Why it matters
MIP is the ongoing cost of FHA's easier entry, and the fact that it does not cancel at 20% equity the way PMI does changes the long-term math. Many FHA borrowers treat the loan as a starter mortgage with a refinance already penciled in.
