Real Estate 101: Private Mortgage Insurance (PMI)
Private Mortgage Insurance (PMI) is one of those ubiquitous real estate industry terms like DOM (days on market) or LTV (loan to value) that sounds simple until a client asks what it means. Then suddenly you're standing in front of someone who just realized those letters "Mean Something Important" and it's our job to explain.
First things first, private mortgage insurance protects lenders, not borrowers. When someone puts down less than 20%, lenders require PMI to cover their risk if the borrower defaults. Your job isn't to defend the system; it's to make it transparent so clients understand what they're paying for and why.
What PMI Does
Private mortgage insurance protects lenders from losses if a borrower defaults on a conventional mortgage with less than 20% down. PMI doesn't protect you. It protects the bank. If you default and the home sells for less than what you owe, PMI covers the lender's shortfall. You still lose your down payment and credit score.
Lenders typically require PMI for down payments under 20% of the home's purchase price, or during refinancing when your equity drops below that threshold. It applies to conventional loans, not government-backed ones like FHA loans, which use mortgage insurance premium (MIP) instead—a different animal entirely.
PMI Cost
You pay PMI premiums monthly, typically 0.5% to 1% of the loan amount annually. On a $400,000 loan with 10% down, that's roughly $2,000 to $4,000 per year—or $167 to $333 monthly—added directly to your mortgage payment.
The actual cost depends on three factors: your credit score, your loan amount, and how much you're putting down. A borrower with a 760+ credit score putting 15% down pays less than someone with a 620 score putting 5% down. Lenders charge higher PMI premiums for riskier loans.
Types of PMI
Borrower-Paid PMI (BPMI) is the most common. The lender adds PMI to your monthly payment, and you pay it until you reach 20% equity (via appraisal) or automatically at 78% loan-to-value (LTV). This is clear, you see the charge every month and you can request cancellation once you hit the threshold.
Single-Premium PMI (SPMI) is a lump sum paid at closing or financed into the loan amount. The advantage is predictability; the disadvantage is that it's non-refundable if you sell or refinance early. If you finance it into the loan, you're also paying interest on the PMI premium for 30 years—a compounding cost.
Lender-Paid PMI (LPMI) shifts the PMI cost to the lender, who then charges you a higher interest rate to cover it. This looks attractive initially—no PMI line item on your payment—but it's harder to cancel. Even after you hit 20% equity, you're still paying the elevated rate. LPMI is a permanent increase in your cost of borrowing.
Remove PMI
Request removal at 80% loan-to-value through an appraisal. Most lenders are compelled to cancel PMI automatically at 78% LTV or at the loan's midpoint, whichever comes first—but you can request earlier cancellation if you've built sufficient equity and your property has appreciated.
The fastest way to cut PMI is accelerated principal payments. Every dollar you pay toward principal reduces your LTV faster. A 15-year mortgage reaches 80% LTV far sooner than a 30-year. Lump-sum payments toward principal—tax refunds, bonuses, and inheritances dramatically shorten the PMI timeline.
Refinancing can also end PMI if rates drop enough to make refinancing economically sensible. A refinance into a new 30-year loan at a lower rate might lower your payment enough to justify closing costs, especially if you're dropping PMI simultaneously.
Real Cost
Here's where people get blindsided. A $400,000 loan with 10% down ($40,000) means a $360,000 mortgage plus roughly $3,000 annually in PMI. Over 10 years—the time it typically takes to reach 20% equity through normal payment—you've spent $30,000 protecting the lender's investment, not yours. If you refinance or sell in year eight, that $24,000 in PMI paid disappears entirely. It's not equity. It's not building wealth. It's insurance for someone else's risk.
The math gets worse if you're paying SPMI (single-premium) financed into the loan. That $10,000 upfront PMI now costs you roughly $18,000 over 30 years because you're paying interest on the insurance itself. LPMI looks cleaner on paper until you realize you're locked into a permanently higher interest rate—paying PMI's cost spread across 30 years of payments instead of a defined timeline. The lender gets paid either way. You're just choosing how to subsidize their risk management.
In Essence
PMI protects lenders, not borrowers; that's not a secret. Understanding how it works, what it costs over time, and how to drop it transforms it from something vague into a visible line item you control. Ask your lender hard questions about which PMI structure saves you money now and in the long run.
