What Is PMI? A Guide for U.S. Homebuyers

Introduction

When buying a home in the United States, many borrowers hear about “PMI” — especially if they’re making a smaller down payment. PMI stands for private mortgage insurance, and it commonly comes up with conventional mortgages.

PMI can be confusing because it’s an extra cost that many borrowers pay, but it is not the same thing as homeowner’s insurance. It also differs from mortgage insurance used on FHA loans.

This guide explains what PMI is, how it works, how it appears on your Loan Estimate and Closing Disclosure (TRID forms), and what general rules exist for cancellation and termination on many conventional loans.

What This Means

PMI is mortgage insurance that is typically required for many conventional loans when the borrower has less than 20% equity at closing — often expressed as an LTV above 80%.

PMI generally protects the lender (or the investor) if the borrower defaults. It does not guarantee approval and does not remove the borrower’s responsibility to repay the loan.

PMI may help some borrowers access conventional financing with smaller down payments, but it increases the total cost of the mortgage. PMI terms and costs vary based on factors such as credit profile, LTV, loan type, and lender options.

How It Works

PMI is typically tied to LTV. When a conventional loan finances more than 80% of the home’s value, lenders often require PMI as a form of credit enhancement.

PMI can be structured in several ways:

• Monthly PMI: A premium added to the monthly mortgage payment.
• Upfront PMI: A one-time premium paid at closing (less common).
• Split premium: A combination of upfront and monthly premiums.
• Lender-paid mortgage insurance: The lender pays PMI but the cost may be reflected in a higher interest rate (structure varies).

PMI should be disclosed on the Loan Estimate and reflected in the Closing Disclosure as part of the total estimated monthly payment and closing costs, when applicable.

For many conventional loans, PMI cancellation and termination rules are governed by the Homeowners Protection Act (HPA). FHA and VA programs have different insurance and fee structures, and those rules should be reviewed separately.

Example Scenario

Consider a simplified purchase example where the borrower puts down 10% on a conventional loan.

Because the LTV is above 80%, many conventional loans in this type of scenario typically require PMI. The PMI premium might appear as a monthly line item in the payment estimate, and it would be included in the estimated “total monthly payment” shown on the Loan Estimate.

The specific cost and duration of PMI depend on the loan terms, the borrower’s profile, and the lender’s PMI structure. This example is for educational illustration only.

Pros and Cons

Common Mistakes

• Mistake 1: Confusing PMI with homeowner’s insurance

  Homeowner’s insurance protects you against certain property risks. PMI is a credit risk product that generally protects the lender if the borrower defaults.

• Mistake 2: Assuming PMI applies to all loan types

  PMI is generally associated with conventional loans. FHA loans use MIP, and VA loans have a funding fee and different rules.

• Mistake 3: Treating PMI removal as automatic at 80%

  Many conventional loans allow borrower-requested cancellation at 80% LTV, but conditions often apply and the request may need to be made in writing.

• Mistake 4: Ignoring appraisal/value concepts

  HPA thresholds are often based on “original value,” and other cancellation pathways may require valuation evidence. Rules vary by loan and servicer.

• Mistake 5: Not reviewing PMI on disclosures

  PMI costs and structure should appear on the Loan Estimate and Closing Disclosure; reviewing these forms can help you compare scenarios.

Frequently Asked Questions

What does PMI stand for?

PMI stands for private mortgage insurance. It is mortgage insurance that generally applies to conventional loans when the down payment is less than 20%.

Who does PMI protect?

PMI typically protects the lender (or the investor in the loan) if the borrower stops making payments. It does not eliminate the borrower’s obligation to repay the loan.

How is PMI paid?

PMI may be paid monthly, as an upfront premium at closing, or as a combination—depending on the loan structure and lender options.

When can PMI end on a conventional loan?

Under the Homeowners Protection Act (HPA), borrower-paid PMI on many conventional loans can be requested to be canceled at 80% LTV (with conditions) and must terminate automatically at 78% LTV if the borrower is current. FHA and VA loans follow different rules.

Is PMI the same as FHA mortgage insurance?

No. PMI is generally used for conventional loans. FHA loans use mortgage insurance premiums (MIP) with different rules and costs.
