Understanding Private Mortgage Insurance (PMI)

Private Mortgage Insurance (PMI) is a type of mortgage insurance that protects the lender if a borrower defaults on their mortgage loan. It is typically required by lenders when a homebuyer makes a down payment of less than 20% of the home's purchase price. PMI ensures that the lender will still recover a portion of their investment if the borrower fails to make payments.

How PMI Works

When you take out a mortgage with a down payment less than 20%, your lender views it as a higher risk. To mitigate this risk, they require you to pay for PMI. This insurance premium is usually added to your monthly mortgage payment, though sometimes it can be paid as a lump sum upfront or a combination of both.

Factors Affecting PMI Rates

The cost of PMI, often expressed as an annual percentage of the original loan amount, varies based on several factors:

  • Loan-to-Value (LTV) Ratio: This is the ratio of the loan amount to the appraised value of the home. The higher your LTV (meaning a smaller down payment), the higher your PMI rate will likely be.
  • Credit Score: A higher credit score generally indicates a lower risk to the lender, often resulting in a lower PMI rate. Borrowers with excellent credit typically qualify for the best rates.
  • Loan Type: The specific terms and type of mortgage can also influence PMI costs.
  • Lender Policies: Different mortgage lenders have their own underwriting guidelines and pricing for PMI.

When Can You Cancel PMI?

In most cases, once your loan-to-value ratio reaches 80%, you can request to have PMI removed from your monthly payments. By law, lenders must automatically terminate PMI once your LTV reaches 78% (provided you are current on your mortgage payments). This means you'll no longer have to pay this extra cost, saving you money over the life of your loan.

Using a PMI Rate Calculator

The calculator above provides an *estimated* PMI rate and monthly cost. You input your home's estimated value, the Loan-to-Value ratio (which is determined by your down payment), and your estimated credit score. The calculator then uses a simplified model to give you an idea of what your PMI might cost. Remember, these are estimates, and your actual PMI rate will be determined by your specific lender after a full underwriting process.
