For many home buyers, one of the largest obstacles is saving up for a down payment. The larger your down payment is, the less risk you pose to the institution lending you the mortgage. That’s where private mortgage insurance comes in, as it allows you to make a smaller down payment while offsetting some of the risk to the lender.

What is private mortgage insurance?

Private mortgage insurance, or PMI, is a type of coverage you buy if you get a conventional mortgage — one that isn't federally guaranteed — and put down less than 20% to purchase a home or have less than 20% equity when refinancing.

PMI is insurance for the mortgage lender’s benefit, not yours. The coverage will pay a portion of the balance due to the mortgage lender in the event you default on the home loan. Usually, you pay for PMI monthly as part of your mortgage payment. The insurance does not prevent you from facing foreclosure or experiencing a decrease in your credit score if you get behind on mortgage payments.

🤓Nerdy Tip

The lender requires PMI because it is assuming additional risk by accepting a lower amount of upfront money toward the purchase. You can avoid PMI by making a 20% down payment.

How much does PMI cost?

The average annual cost of PMI typically ranges from $30 to $70 per $100,000 borrowed, according to Freddie Mac. Borrowers with excellent credit get the lowest PMI rates.

This means that if you got a $350,000 mortgage, you can expect to pay between $105 and $245 a month towards PMI.

The cost of private mortgage insurance depends on several factors:

  • The size of the mortgage loan. The more you borrow, the more you pay for PMI.

  • Down payment amount. The more money you put down for the home, the less you pay for PMI.

  • Your credit score. PMI will cost less if you have a higher credit score. Generally you'll see the lowest PMI rates for a credit score of 760 or above.

  • The type of mortgage. PMI may cost more for an adjustable-rate mortgage than a fixed-rate mortgage. Because the rate can go up with an adjustable-rate mortgage, the loan is riskier than a fixed-rate loan, so PMI tends to be higher.

Estimating the cost of PMI before you get a mortgage can help you determine how much home you can afford.

How to pay for PMI

Typically, the PMI cost, called a “premium,” is added to your monthly mortgage payment. You can see the premium on your Loan Estimate and Closing Disclosure mortgage documents.

Sometimes lenders offer the option to pay the PMI cost in one upfront premium or with a combination of upfront and monthly premiums.

Is PMI tax-deductible?

No, private mortgage insurance is currently not tax deductible on a personal residence; however, insurance premiums can be deducted in the year paid for investment or rental properties.

How do I get rid of PMI?

Once your mortgage principal balance is less than 80% of the original appraised value, you can ask the mortgage loan servicer to cancel PMI. Often there are additional requirements, such as a history of timely payments and the absence of a second mortgage.

If you don't request cancellation, the lender or service must cancel PMI once your mortgage balance reaches 78% of the original value of the home.

Save money on PMI

Some state housing authorities offer conventional home loans with reduced mortgage insurance costs and below-market interest rates for first-time home buyers. Check out the programs available in your state for details.

Other low-down-payment mortgage options

Conventional loans with private mortgage insurance aren't the only choice if you have limited cash for a down payment. A government-backed loan may fit the bill:

FHA loans, insured by the Federal Housing Administration, require as little as 3.5% down and are a good option for borrowers with lower credit scores.

USDA loans, backed by the U.S. Department of Agriculture, require no down payment and are for lower- to moderate-income home buyers in designated rural areas.

VA loans, guaranteed by the Department of Veterans Affairs, require no down payment and are for active-duty and veteran military members.

PMI requirements by loan type

FHA loans

Requirements include a “mortgage insurance premium,” consisting of an upfront charge of 1.75% of the loan amount and an annual fee ranging from 0.15% to 0.75% of the loan amount. The amount charged and term required (either the full loan period or 11 years) depends on the size of your down payment.

VA loans

Requirements include a "funding fee,” which ranges from 1.25% to 3.3% of the loan amount, depending on your down payment and whether it’s your first VA loan.

USDA loans

Borrowers pay a “guarantee fee,” which includes an initial fee of 0.60 to 0.65% of the loan amount and an annual fee of 0.25% to 0.35% of the loan amount.

Frequently asked questions

PMI stands for private mortgage insurance, a type of insurance policy that protects the lender if a borrower defaults on a home loan. Lenders usually require you to pay for PMI if you put less than 20% down on a conventional mortgage.

There are a couple of ways that you can avoid PMI without making a 20% down payment. With an 80-10-10 loan, also called a piggyback loan, you make a 10% down payment and have two mortgages that cover the other 90%. You could also consider a government-backed loan, such as an FHA or USDA loan, which do not require PMI (but do have their own associated fees).

Yes, your credit score affects how much private mortgage insurance will cost. A borrower with a higher credit score would likely pay less for PMI than someone who has a lower credit score, even with the same down payment and mortgage amount.

If you’re buying a $300,000 home with less than 20% down, you can expect to spend between $90 and $210 per month on PMI.
