Private Mortgage Insurance (PMI)

PMI is underwritten by private mortgage insurance companies that assume a portion of the lender's risk on high-LTV loans. When a borrower defaults and the property goes into foreclosure, the PMI company reimburses the lender for a predetermined percentage of the loss — typically 15% to 30% of the claim amount. This risk transfer allows lenders to offer conventional loans with down payments as low as 3% (through Fannie Mae's HomeReady or Freddie Mac's HomeOne programs) while still meeting the safety and soundness requirements of their investors. There are several PMI structures available. Monthly PMI (MPMI) is the most common: the premium is divided into 12 monthly installments and added to the borrower's mortgage payment. Single-premium PMI is paid as a one-time lump sum at closing, which can be rolled into the loan amount or paid in cash; this eliminates the monthly PMI charge but requires a higher upfront cost. Split-premium PMI combines a smaller upfront payment with lower monthly premiums. Lender-paid mortgage insurance (LPMI) replaces the borrower-paid monthly premium with a higher interest rate — the lender buys the PMI policy itself and passes the cost through the rate rather than a separate line item.

The cost of PMI is determined by rating tiers based on the borrower's credit score and the LTV ratio. A borrower with a 760 credit score and 85% LTV might pay 0.30% annually, while a borrower with a 680 credit score and 97% LTV could pay 1.5% or more annually. PMI premiums are not escrowed separately from the mortgage payment — they are included in the total monthly payment figure shown on the Loan Estimate and Closing Disclosure, and they are listed as a component of the projected payment. It is important to note that PMI is not the same as homeowners insurance. Homeowners insurance protects you and your lender against property damage from fire, storms, theft, and liability claims, while PMI only protects the lender against default. You are required by your lender to carry both policies, but they serve completely different purposes. The PMI premium is typically paid through your monthly mortgage payment and is held in a suspense account by the lender, who then forwards the aggregate premium to the PMI company monthly or annually. Some borrowers mistakenly believe that PMI protects them if they lose their job or become disabled, but it does not — PMI only covers the lender's losses in the event of foreclosure.

PMI has a significant impact on monthly housing affordability and long-term wealth building. For a borrower with a median credit score putting 5% down on a $400,000 home, PMI adds approximately $150 to $250 per month to the payment — money that goes toward insurance that protects the lender, not the borrower. Over five years before cancellation, that is $9,000 to $15,000 in premiums that could have gone toward building equity or investing. However, PMI serves as a powerful enabler for first-time homebuyers who cannot afford a 20% down payment, which nationally averages $80,000 on the median-priced home. Without PMI, many creditworthy borrowers would be shut out of homeownership entirely. The key to minimizing PMI costs is to understand the cancellation rules under the Homeowners Protection Act of 1998. The HPA requires lenders to automatically terminate PMI when the borrower's LTV reaches 78% based on the original amortization schedule, provided the borrower is current on payments. Borrowers can also request cancellation in writing once the LTV reaches 80% based on the original property value or a new appraisal.

However, there are important nuances to PMI cancellation that borrowers often overlook. First, the automatic termination at 78% LTV is based on the original amortization schedule, not the actual loan balance. If you make extra principal payments and reach 78% LTV ahead of schedule, the automatic termination will not occur until the scheduled date — you must submit a written request for early cancellation. Second, lenders may require a new appraisal at your expense (typically $400 to $600) to confirm the current property value, especially if the cancellation is based on appreciation rather than principal paydown. Third, some loans are designated as high-risk and the lender may not permit cancellation, such as loans with late payment history or those classified as non-conforming. Fourth, PMI is tax-deductible for some borrowers under certain income limits, though the deductibility was eliminated by the Tax Cuts and Jobs Act of 2017 for most taxpayers, with periodic renewals by Congress in subsequent years. Borrowers should consult a tax professional to determine their eligibility. Finally, borrowers with government-backed FHA loans should be aware that FHA MIP works differently. FHA loans require an upfront mortgage insurance premium (UFMIP) of 1.75% of the loan amount plus annual MIP for either 11 years or the life of the loan, depending on the LTV and loan term. Unlike PMI, FHA MIP cannot be canceled if your down payment was less than 10% — it remains for the life of the loan, making PMI the more attractive option for borrowers who anticipate building equity and canceling insurance within a few years.
