PMI (Private Mortgage Insurance)

Quick Definition

Private Mortgage Insurance (PMI) is insurance that a borrower pays to protect the lender, not the borrower, when the down payment on a conventional mortgage is less than 20% of the home's purchase price. PMI compensates the lender if the borrower defaults and the foreclosure sale does not fully cover the outstanding loan balance. It adds $50 to $500+ per month to the borrower's housing costs until the loan-to-value ratio reaches 80%.

What It Means

PMI exists because loans with less than 20% down are statistically more likely to default. Borrowers with less equity have less financial skin in the game. The lender requires PMI to offset this elevated risk. The paradox: you pay the premiums, but the lender is the beneficiary. PMI provides you nothing. It only protects the lender.

Despite being a pure cost to the borrower, PMI enables homeownership for buyers who cannot save a full 20% down payment. According to the Urban Institute's 2025 Mortgage Insurance Data, the PMI industry has enabled homeownership for nearly 40 million borrowers over the past 68 years. In 2024, 36.1% of GSE (Fannie Mae and Freddie Mac) loans carried PMI, rising to 44.1% of purchase loans.

When PMI Is Required

PMI Cost Factors and Typical Rates (2026)

PMI rates are based on Fannie Mae and Freddie Mac pricing guidelines. Your exact rate depends primarily on credit score and loan-to-value ratio.

Monthly Cost on a $400,000 Loan

The biggest driver of cost is credit score. A borrower with a 680 score pays over $2,000 more per year in PMI than a borrower with a 760+ score on the same loan.

How to Cancel PMI

The Homeowners Protection Act (HPA) of 1998 gives borrowers legal rights to cancel PMI:

Acceleration timeline example: $320,000 loan at 6.5%, 30-year fixed (2026 rates):

• Original amortization reaches 78% LTV: approximately Year 11 of 30
• With extra $200/month payments: approximately Year 8
• With 10% appreciation: potentially Year 5-6

PMI Types

LPMI trade-off: A 0.25-0.375% rate increase on a $320,000 loan = $800-$1,200/year extra interest, potentially for 30 years. BPMI cancels in 7-10 years. BPMI is usually better for buyers who plan to stay and build equity.

PMI vs. FHA MIP: Key Differences

For borrowers with 5-10% down and good credit (680+), conventional plus PMI is usually cheaper than FHA plus MIP because PMI eventually cancels while FHA MIP on low-down-payment loans is permanent. The long-term savings can exceed $50,000 over the life of the loan.

The "Piggyback Loan" PMI Avoidance Strategy

Some buyers use a "piggyback" second mortgage to avoid PMI on a conventional loan:

80/10/10 structure:

• 80% first mortgage, no PMI required
• 10% second mortgage (HELOC or fixed second)
• 10% down payment

Trade-off: The second mortgage typically has a higher rate (7-9%) versus the first mortgage. The question is whether the higher rate on the second mortgage costs more or less than PMI would. In most cases with good credit, PMI is cheaper than the piggyback approach unless you plan to pay off the second mortgage quickly.

PMI Tax Deduction: Reinstated for 2026

Starting with tax year 2026, the PMI tax deduction has been permanently reinstated by the One Big Beautiful Bill Act. PMI premiums are now treated as deductible mortgage interest for qualified borrowers, subject to income phase-outs. The deduction had expired after 2021 and was not available for tax years 2022 through 2025.

Consult a tax professional to confirm your eligibility, as income limits and other restrictions apply.

Key Points to Remember

• PMI protects the lender, not you; you pay premiums that benefit someone else
• Required on conventional loans when down payment is less than 20%
• PMI rates range from 0.15% to 1.55% of the loan amount annually based on Fannie Mae/Freddie Mac guidelines
• On a $400,000 loan, monthly PMI ranges from $50 (760+ score, 15% down) to $517 (620 score, 3% down)
• Federal law (HPA) requires automatic cancellation at 78% LTV and borrower rights to cancel at 80%
• Final termination occurs at the midpoint of the loan term (year 15 of a 30-year), regardless of LTV
• VA loans have no PMI, one of the most significant VA benefits
• FHA MIP is similar to PMI but cannot be cancelled for most borrowers
• The PMI tax deduction is permanently reinstated starting tax year 2026

Common Mistakes to Avoid

• Not checking your credit score before applying: PMI rates are heavily credit-score dependent. A borrower with a 620 score pays 1.55% annually versus 0.38% for a 760+ score on a 3% down loan. Improving your score by 60 points before buying could save $400+ per month.
• Choosing LPMI without doing the math: LPMI avoids the monthly PMI charge but locks in a higher interest rate for the life of the loan. On a $400,000 loan, a 0.375% rate premium costs $1,500/year forever. BPMI at $200/month ($2,400/year) cancels in 7-9 years. If you plan to stay longer than that, BPMI is cheaper.
• Forgetting to request cancellation at 80% LTV: Automatic cancellation only happens at 78% LTV based on the original amortization schedule. You must actively request cancellation at 80% LTV. If your home has appreciated, you may be eligible sooner through a new appraisal.
• Assuming FHA MIP and PMI are the same: FHA MIP on loans with less than 10% down lasts for the entire life of the loan. PMI on conventional loans can be cancelled at 80% LTV. This difference can cost $30,000-$50,000 over a 30-year loan. Borrowers with credit scores above 680 should compare conventional PMI vs. FHA MIP carefully.

Frequently Asked Questions

Q: Is PMI tax-deductible? A: Yes, starting with tax year 2026. The One Big Beautiful Bill Act permanently reinstated the PMI deduction, which had expired after 2021. PMI premiums are treated as deductible mortgage interest, though income phase-outs apply. Consult a tax professional to confirm your eligibility.

Q: Can I cancel PMI as soon as I have 20% equity? A: You can request cancellation at 80% LTV based on the original purchase price and original amortization schedule. Lenders are not required to use current appreciated value for borrower-initiated cancellation unless you order an appraisal and meet specific seasoning requirements (typically 2+ years of payments). Some lenders allow cancellation based on current value after 2 years (80% LTV) or 5 years (75% LTV). Check your lender's specific policy.

Q: Should I put 20% down to avoid PMI, or invest the extra cash? A: The math depends on the PMI rate, your investment return expectation, and how long you will carry PMI. If PMI is $200/month and you expect 7% returns on invested capital, investing the down payment difference can be better than putting 20% down, especially if PMI will only last 5-7 years. In a 6.5%+ mortgage rate environment, paying down debt may outperform investment returns. Use our house affordability calculator to model different down payment scenarios.

Q: Who are the main PMI providers? A: The top six PMI companies are MGIC, Genworth, Radian, Essent, National MI, and Arch. Your lender shops among these providers and you typically do not get to choose. The average private MI in-force premium yield has declined from 52.5 basis points in 2017 to 39.4 basis points in 2024, reflecting increasing competition and better risk modeling.

Q: How does PMI compare to FHA MIP on a $400,000 loan with 3.5% down? A: FHA requires $7,000 upfront MIP (1.75%) plus approximately $190/month in annual MIP that lasts the entire 30-year loan life. Total over 30 years: $7,000 + $68,400 = $75,400. Conventional with 3% down (97% LTV) at a 680 credit score: no upfront premium, approximately $277/month in PMI for 7-9 years until 80% LTV = $23,000-$30,000. Then $0. Conventional is 20-30% cheaper even with higher monthly PMI, for borrowers who qualify.
