What PMI Means in Plain English
PMI stands for Private Mortgage Insurance. When you put less than 20% down on a home, your lender requires you to pay for this insurance. The key thing to understand right away: PMI protects the lender, not you. If you default, the insurance company pays out to the lender — you still lose your house.
This isn’t a scam. Lenders take on real risk when they finance more than 80% of a home’s value. PMI is their hedge against that risk. You’re paying for coverage on a risk the lender is taking, which is why it feels frustrating. But it’s also a tollbooth, not a permanent fixture — once you’ve built enough equity, it goes away.
The cost is meaningful but finite. PMI typically runs 0.5-1.5% of your loan amount annually. On a $350,000 loan at 1%, that’s $3,500 per year — about $292 per month added to your mortgage payment.
How PMI Works
PMI is usually rolled into your monthly mortgage payment automatically. You don’t get a separate bill — the lender collects it along with your principal, interest, taxes, and insurance.
There are three ways PMI ends:
- Automatic cancellation: Under the Homeowners Protection Act, lenders must automatically cancel PMI when your loan balance reaches 78% of the original purchase price (not current value) — as long as you’re current on payments.
- Requested cancellation: You can request removal when your balance reaches 80% LTV based on the original purchase price. You may need to pay for an appraisal to confirm the value, and you must have a good payment history.
- Refinancing: If home values have risen significantly, refinancing may result in a new loan-to-value ratio below 80%, eliminating PMI on the new loan.
Note: FHA loans have their own version of mortgage insurance (MIP) that behaves differently — if your FHA loan originated after June 2013 with less than 10% down, MIP sticks for the life of the loan. That’s a reason some buyers prefer conventional loans once they qualify.
Why PMI Matters to You
PMI is a real cost, but the decision to avoid it by waiting to save 20% isn’t always the right call. Here’s the math that often gets overlooked: if you’re renting while saving toward a larger down payment, and home prices in your market are rising 5-6% annually, you’re chasing a moving target.
On a $400,000 home appreciating at 5%: in 3 years it’s worth $463,050. You’ve been paying rent instead of building equity, and now you need a larger down payment on a more expensive home. The PMI you would have paid — say $250/month for 24 months before hitting 80% LTV — totals $6,000. That’s likely less than the additional down payment you’d need to keep up with appreciation.
PMI makes sense to avoid when you’re close to 20% and just need a few more months. It makes less sense to obsess over when it means sitting out of a rising market for years.
Quick Example
Sam buys a $350,000 home with 10% down ($35,000). The loan balance is $315,000 and PMI costs 0.9% annually = $2,835/year ($236/month).
Each month, Sam’s payment reduces the loan balance slightly. The home also appreciates. After about 4 years, between principal payments and modest appreciation, the loan balance drops below 80% of the original purchase price and Sam requests PMI cancellation. Total PMI paid: roughly $11,000 over four years — while building equity in a home that appreciated by $70,000+ in that same period.
Common Misconceptions
- PMI protects you as the homeowner. It doesn’t. PMI protects the lender’s investment if you default and they have to foreclose and sell at a loss.
- You’re stuck with PMI for the life of the loan. No — you can request removal at 80% LTV, and it’s automatically canceled at 78% LTV on conventional loans.
- You should always wait until you have 20% to buy. Sometimes yes, sometimes no. It depends on how fast home prices are rising and what you’re doing with your money in the meantime.
