What Private Mortgage Insurance Is and Why Lenders Require It

Private mortgage insurance (PMI) is a monthly fee added to your mortgage payment when you put down less than 20 percent of the home's purchase price. The insurance protects the lender, not you — if you stop paying the mortgage, PMI covers the lender's loss. You pay the premium, but the lender collects the benefit.

Lenders require PMI because a smaller down payment means higher risk. If you default on a $300,000 mortgage after putting down only 5 percent, the lender has already lost money before the foreclosure process even begins. PMI shifts that risk to an insurance company, which allows lenders to offer mortgages to buyers who cannot save a full 20 percent down.

PMI typically costs between 0.5 and 1.5 percent of your loan amount per year, though the exact rate depends on your credit score, the size of your down payment, and the type of loan. On a $300,000 mortgage with 10 percent down, PMI might run $150 to $450 per month. That money goes into your mortgage payment every month until you reach 20 percent equity in the home.

Key Takeaways

  • PMI is required when you put down less than 20 percent, and you pay the premium even though the insurance protects the lender, not you.
  • The cost ranges from 0.5 to 1.5 percent of your loan annually, depending on your credit score and down payment size.
  • You can remove PMI once you reach 20 percent equity through a combination of payments and home appreciation, or by refinancing into a conventional loan.
  • Putting down 20 percent upfront, choosing an FHA loan, or using a piggyback mortgage are the main ways to avoid PMI entirely.
  • PMI removal is not automatic — you must request it in writing once you meet the lender's requirements.

How Much PMI Actually Costs Over Time

The total cost of PMI depends on how long you carry it. If you buy a $300,000 home with 10 percent down ($30,000) and a 30-year mortgage at 7 percent interest, your loan is $270,000. With PMI at 1 percent annually, you pay roughly $225 per month for insurance alone. Over five years, that is $13,500 in PMI payments — money that builds no equity and disappears once you reach 20 percent equity.

The longer you carry PMI, the more it costs. If you stay in the home for 10 years before reaching 20 percent equity through payments and appreciation, you could pay $27,000 or more in PMI. That same $27,000 could have reduced your principal or gone toward home repairs and maintenance.

PMI costs also vary by loan type. Conventional loans (the most common type) allow you to remove PMI once you reach 20 percent equity. FHA loans, by contrast, charge mortgage insurance for the life of the loan if you put down less than 10 percent, or for at least 11 years if you put down 10 percent or more. VA and USDA loans do not require PMI at all, though they charge different upfront fees.

The Down Payment Threshold: Why 20 Percent Matters

Twenty percent down is the magic number because it is where lenders stop requiring mortgage insurance on conventional loans. At 20 percent equity, the lender's risk drops enough that they no longer need the insurance cushion. Below 20 percent, PMI is mandatory. Above 20 percent, it is not.

This does not mean you need $60,000 cash to buy a $300,000 home. Many buyers put down 5 to 10 percent and accept PMI as the cost of homeownership now rather than waiting years to save more. The trade-off is real: you pay PMI monthly, but you build equity in the home when ready and benefit from any price appreciation.

Some buyers split the difference with a piggyback mortgage — a second loan that covers part of the down payment. For example, you might put down 10 percent in cash, take out an 80 percent first mortgage, and a 10 percent second mortgage (often called an 80/10/10 loan). This avoids PMI because the first mortgage is exactly 80 percent of the purchase price. The second mortgage typically carries a higher interest rate, so you need to compare the total cost against PMI.

How To Remove PMI From Your Mortgage

PMI removal requires you to reach 20 percent equity in your home. This happens through a combination of mortgage payments (which reduce the principal) and home appreciation (which increases the home's value). Once you hit that mark, you must request removal in writing — it does not happen automatically, even though federal law requires lenders to allow it.

The timeline depends on your down payment and local market conditions. If you put down 10 percent and the home appreciates 3 percent per year, you might reach 20 percent equity in 5 to 7 years. If you put down 5 percent and the market is flat, it could take 10 years or longer. Some lenders will remove PMI automatically once you reach 20 percent equity through payments alone (not appreciation), but you should not count on this — contact your lender in writing when you believe you have reached the threshold.

Refinancing is another path. If your home has appreciated significantly or your credit score has improved, you may be able to refinance into a new conventional loan without PMI. Refinancing costs money (closing costs typically run 2 to 5 percent of the loan amount), so you need to calculate whether the PMI savings over time justify the upfront expense. A refinance makes sense if you plan to stay in the home long enough to recoup those costs.

Putting Down 20 Percent: The Straightforward Approach

The simplest way to avoid PMI is to save 20 percent down before you buy. On a $300,000 home, that is $60,000. For many first-time buyers, this feels impossible, which is why PMI exists — it lets you buy sooner with less cash saved.

If you can reach 20 percent down, the math is clear: you avoid all PMI payments, your monthly mortgage is lower, and you build equity faster. The trade-off is time — you may rent for several more years while saving. Whether that makes sense depends on your local market (rents versus home prices), your job stability, and your personal timeline.

Some buyers reach 20 percent down through a combination of savings and a gift from family. Federal loan programs allow gift money from relatives, though you typically need to document that it is a gift, not a loan. If you are considering this route, ask your lender what documentation they require before you accept the money.

FHA Loans and Mortgage Insurance Premiums

FHA loans are backed by the Federal Housing Administration and allow down payments as low as 3.5 percent. They do not charge PMI, but they do charge mortgage insurance premiums (MIP) — a different form of insurance that works similarly but has different rules.

FHA loans charge an upfront mortgage insurance premium (typically 1.75 percent of the loan amount, paid at closing or rolled into the loan) and an annual premium (0.55 to 0.80 percent depending on the loan term and down payment). If you put down less than 10 percent, you pay the annual premium for the life of the loan — you cannot remove it. If you put down 10 percent or more, the annual premium drops off after 11 years.

For some buyers, FHA is cheaper than a conventional loan with PMI. For others, it is more expensive. You need to compare the total cost of each option with your lender before deciding. FHA also has stricter property requirements and limits on how much you can borrow, so it is not available for every home or every buyer.

VA and USDA Loans: No PMI Required

If you are a military veteran or active-duty service member, a VA loan requires no down payment and no PMI. Instead, you pay a one-time funding fee (typically 1.4 to 3.6 percent of the loan amount, depending on your service branch and down payment). The funding fee is usually rolled into the loan, so you do not pay it upfront.

USDA loans are available to rural homebuyers who meet income limits. They also require no down payment and no PMI, though they charge a may provide fee (1 percent upfront, plus 0.35 percent annually for 30 years). Like VA loans, these fees are typically rolled into the loan amount.

Both programs have trade-offs. VA and USDA loans come with stricter property requirements, longer approval timelines, and limits on how much you can borrow. But if you are may be able to access, the lack of PMI and the ability to buy with zero down can make a significant difference in affordability.

Frequently Asked Questions

Can I remove PMI before I reach 20 percent equity?

Federal law requires lenders to remove PMI automatically once you reach 20 percent equity through principal payments alone. Some lenders will remove it earlier if you request it and your home has appreciated significantly, but this is not may provide. Ask your lender about their policy on early removal.

Does PMI ever go away on its own?

No. PMI does not disappear automatically, even after you reach 20 percent equity. You must contact your lender in writing and request removal. Federal law requires lenders to remove it once you hit the threshold, but you have to ask. Check your loan documents for your lender's specific requirements.

Is PMI tax deductible?

PMI was tax deductible for some borrowers in past years, but that deduction expired at the end of 2023. Check with a tax professional about your specific situation, as rules can change and some circumstances may still may have access to.

What is the difference between PMI and mortgage insurance on an FHA loan?

PMI protects the lender on conventional loans and can be removed once you reach 20 percent equity. FHA mortgage insurance premiums (MIP) serve a similar purpose but have different costs and removal rules — annual MIP on FHA loans with less than 10 percent down lasts for the life of the loan and cannot be removed.

Should I wait to buy until I have 20 percent down?

That depends on your local market, job stability, and personal timeline. If home prices are rising faster than you can save, buying sooner with PMI may build more equity than waiting. If prices are flat or falling, waiting to save more makes financial sense. Run the numbers with your lender for your specific situation.
