What Is PMI (Private Mortgage Insurance)? Complete Guide

Here's something that surprises a lot of borrowers when I explain it: PMI doesn't protect you. It protects the bank.

That's not a criticism — it's just an important frame for understanding the product. Private mortgage insurance (PMI) exists because lenders take on more risk when you buy a home with less than 20% down. PMI compensates the lender if you default. You pay for it, but you receive no direct benefit from it.

That said, PMI is also what makes homeownership accessible to millions of buyers who don't have six figures sitting in a savings account. Without PMI, most conventional lenders would require 20% down on every loan. Understanding how it works — what it costs, when you're required to carry it, and exactly how to get rid of it — can save you real money.

The PMI Myth That Costs People Money

The most damaging misconception I encounter: "PMI is forever." People assume it's baked into their payment permanently, like property taxes. As a result, they either wait years to think about cancellation, or they over-correct and delay buying entirely to save a 20% down payment — sometimes for 5–7 years while prices appreciate out of reach.

PMI is temporary. It has a defined legal termination point, and often you can accelerate that termination with targeted extra payments or a new appraisal.

What PMI Actually Costs

PMI is typically expressed as an annual percentage of your loan balance, paid monthly as part of your mortgage payment. According to the Urban Institute's Housing Finance Policy Center, rates range from 0.46% to 1.50% annually, with exact pricing driven by two main factors: your loan-to-value ratio and your credit score.

Here's what that looks like in real dollars on a $350,000 loan:

| Credit Score | PMI Rate (Annual) | Monthly PMI Cost | Annual PMI Cost | |---|---|---|---| | 760+ | 0.46% | $134 | $1,610 | | 720–759 | 0.65% | $190 | $2,275 | | 680–719 | 0.95% | $277 | $3,325 | | 640–679 | 1.25% | $365 | $4,375 | | 620–639 | 1.50% | $438 | $5,250 |

The impact of credit score on PMI is significant — a borrower with a 760 score pays roughly one-third of what a borrower with a 620 score pays for the same loan amount. This is one reason why improving your credit score before applying for a mortgage matters so much in practice.

PMI is also sensitive to your down payment. At 5% down, you'll pay more than at 10% down, even with the same credit score. Most mortgage lenders price PMI in "buckets" — so going from 9.9% down to 10% might drop your PMI rate by 0.15–0.25%.

How PMI Is Structured

PMI comes in three common structures:

Borrower-Paid PMI (BPMI): The most common form. Added as a monthly line item to your mortgage payment. This is what most people mean when they talk about PMI.

Lender-Paid PMI (LPMI): The lender pays the premium upfront in exchange for a higher interest rate on your loan — typically 0.25–0.75% higher. No monthly line item, but the higher rate is permanent for the life of the loan. This often makes sense if you'll sell or refinance within 5–7 years; it almost never makes sense for a long-term hold.

Single-Premium PMI: You pay one lump sum at closing (often 1.0–3.0% of the loan amount) to eliminate the monthly charge. Can work well if you have extra cash at closing and plan to stay long-term, but you lose that money if you sell or refinance before breakeven.

The Homeowners Protection Act: Your Legal Right to Cancel

Congress passed the Homeowners Protection Act (HPA) in 1998 specifically to address the fact that many borrowers were paying PMI long after they'd built sufficient equity. The CFPB enforces these provisions:

Automatic Cancellation: Your lender must cancel PMI when your loan balance reaches 78% of the original purchase price — no action required on your part. For a $350,000 purchase, that's when you owe $273,000.

Borrower-Requested Cancellation: You can request cancellation earlier, when your loan balance reaches 80% LTV based on the original purchase price. To qualify, you typically need a good payment history (no 30-day late payments in the past year) and written documentation that your home's value hasn't declined.

Cancellation Based on Current Value: If your home has appreciated significantly, some lenders will order a new appraisal and cancel PMI if current LTV is below 80%. This requires at least two years of payments on most conventional loans, and the process varies by lender and loan type.

Use the mortgage calculator to model your loan balance over time and estimate when you'll cross these thresholds.

PMI vs. FHA Mortgage Insurance Premium (MIP)

FHA loans carry a different product: MIP, or Mortgage Insurance Premium. The CFPB and HUD set different rules for MIP than for conventional PMI.

| Feature | Conventional PMI | FHA MIP | |---|---|---| | Upfront cost | None (usually) | 1.75% of loan amount at closing | | Annual cost | 0.46%–1.50% | 0.15%–0.75% | | Cancellation threshold | 78–80% LTV | Only if 10%+ down payment (after 11 years) | | Lifetime requirement? | No | Yes, if down payment < 10% | | Credit score impact | Significant | Minimal (same rate at 580+) |

In March 2026, FHA reduced annual MIP rates by 30 basis points across the board — saving the average FHA borrower approximately $800 per year, according to HUD. Even with that reduction, the mandatory lifetime coverage (for borrowers who put down less than 10%) means FHA loans can carry insurance costs for decades longer than conventional loans.

This is a critically important point: for many borrowers with decent credit (680+), a conventional loan with PMI is cheaper over time than an FHA loan with MIP, even if the FHA rate looks lower at first glance. The math changes quickly once you factor in that conventional PMI disappears and FHA MIP often doesn't.

When FHA Makes More Sense Anyway

Despite the lifetime MIP issue, FHA loans are often the right call for:

• Borrowers with credit scores below 620 (conventional PMI pricing becomes punishing)
• Borrowers with higher debt-to-income ratios (FHA allows up to 57% DTI in some cases; conventional caps at 45–50%)
• Buyers purchasing fixer-uppers who need FHA 203(k) renovation financing
• Borrowers who've had a bankruptcy or foreclosure in the past 3–4 years

Strategies to Eliminate PMI Faster

Strategy 1: Make Extra Principal Payments

Every dollar of extra principal you pay accelerates your path to 80% LTV. Use the amortization calculator to see exactly how much faster you'd reach the cancellation threshold with various extra payment amounts.

On a $350,000 loan at 6.75% for 30 years, an extra $250/month in principal cuts roughly 7 years off the loan and could eliminate PMI 4–5 years sooner than scheduled. At $400/month in PMI savings, that's $19,000–$24,000 in avoided insurance costs.

Strategy 2: Request a New Appraisal After Appreciation

If your home has appreciated significantly — common in markets with strong price growth — you may qualify for early PMI cancellation based on current market value rather than original purchase price. Most lenders require:

• At least 24 months of payments (some require 12 months with 25%+ appreciation)
• Current LTV below 75–80% based on appraised value
• No 30-day late payments in the past 12 months
• An appraisal ordered through the lender (expect $400–$700 cost)

The calculus: if an appraisal costs $500 but eliminates $300/month in PMI, you break even in under two months. Worth it.

Strategy 3: Refinance

If rates have dropped significantly since your original loan, refinancing can serve a dual purpose: lower rate and elimination of PMI (if new LTV is below 80%). The refinance calculator can help you model whether the refi math works in your specific situation.

Strategy 4: Piggyback Loan (80-10-10)

At origination, some buyers avoid PMI entirely by structuring two loans: a primary mortgage at 80% LTV (no PMI), plus a second mortgage (often a HELOC) at 10%, with 10% down payment. The combined payment may be lower than an 80%+ LTV loan with PMI — especially for borrowers with good credit. This strategy requires careful math and a lender willing to structure it.

The 20% Down Debate

I want to address this directly because I think a lot of buyers make suboptimal decisions based on outdated advice.

The conventional wisdom "always put 20% down to avoid PMI" made more sense in eras of lower home prices and higher PMI rates. Today, with median home prices above $400,000 in most metros, saving a 20% down payment ($80,000+) can take 7–10 years for the average household.

During those years, you're paying rent — often comparable to or more than a mortgage payment — and missing equity appreciation. A buyer who purchased a $400,000 home in 2019 with 5% down ($20,000) paid PMI for roughly 4–5 years, but also captured $120,000–$150,000 in appreciation while their peer was still renting and saving.

The right question isn't "how do I avoid PMI?" — it's "what's the total cost of ownership at different down payment levels, and how does it compare to continued renting?" Use the affordability calculator to run those comparisons with your actual numbers.

FAQ: Private Mortgage Insurance

Is PMI tax-deductible?

PMI deductibility has been on-again, off-again for years in Congress. As of 2026, the PMI deduction has expired and is not available. Check with a tax advisor for current-year status, as Congress occasionally renews it retroactively.

Can I negotiate my PMI rate?

Not directly with the PMI insurer — rates are set by the insurer (companies like Radian, MGIC, and Arch MI) based on your loan profile. What you can negotiate: which lender you use, and whether you structure the loan as borrower-paid or single-premium PMI. Shopping multiple lenders sometimes reveals different PMI structures and effective rates.

Does PMI protect me if I lose my job or can't make payments?

No. PMI protects the lender, not you. If you lose your job and miss payments, the insurance pays the lender — not you. If you're worried about payment protection, look into mortgage protection life insurance or disability insurance as separate products.

What if my lender refuses to cancel PMI when I reach 80% LTV?

File a written request and keep documentation. If the lender refuses to cancel PMI at 80% LTV despite your meeting the Homeowners Protection Act requirements, file a complaint with the Consumer Financial Protection Bureau (consumerfinance.gov). The HPA gives borrowers clear legal rights, and the CFPB takes these violations seriously.

Does PMI affect my mortgage rate?

PMI is separate from your interest rate. However, some lenders offer "lender-paid PMI" structures where the PMI cost is embedded in a higher interest rate. This effectively blends the costs, but the underlying mortgage rate itself is set independently of PMI.

How do I know if my PMI has been canceled?

Your lender is required to send written notice when PMI is canceled. If you've reached the 78% LTV threshold and haven't received notice, contact your loan servicer in writing. Request written confirmation of the PMI termination date.

Can I get PMI removed if my home value drops?

No. If your home's current value is lower than when you bought, the lender will not cancel PMI based on a new appraisal — your LTV based on original purchase price still governs automatic cancellation. You'd need to continue making payments until the 78% threshold is met based on original value.

• ---

PMI is a cost worth understanding precisely, not dreading in the abstract. For many buyers — especially those purchasing in appreciating markets — the total PMI paid over 4–5 years is a reasonable price for getting into a home years earlier than a 20% down payment strategy would allow.

The key is knowing your cancellation rights, tracking your LTV progress, and acting proactively when you cross the 80% threshold. Your lender will not volunteer this information — you have to initiate it.

If you want to model exactly when you'll hit the 80% LTV mark, the amortization calculator will show you your loan balance at any point in the future. Set a calendar reminder for when you're projected to reach it — and then follow through.
