What Is PMI (Private Mortgage Insurance)?
PMI (Private Mortgage Insurance) is a type of insurance that protects lenders—not borrowers—if you default on your loan. It is typically required when your down payment is less than 20% of the home price.
In most cases:
- PMI is added to your monthly mortgage payment
- It continues until you reach 20% equity in your home
- The cost depends on your loan size and risk profile
Lenders like Fannie Mae and Freddie Mac commonly require PMI for conventional loans with low down payments.
Why Use a PMI Mortgage Calculator?
