What Is Private Mortgage Insurance (PMI) and How Do You Avoid It?
Private mortgage insurance is one of the most misunderstood costs in homebuying. Buyers either don’t know it exists until closing day, or they avoid it at all costs when avoiding it doesn’t actually make financial sense. Here’s the full picture.
What PMI Is — and What It Isn’t
PMI is insurance that protects your lender — not you — if you default on your mortgage. It is required on conventional loans when your down payment is less than 20% of the purchase price.
The logic: when you put down less than 20%, the lender is financing more than 80% of the home’s value. That higher loan-to-value ratio means more exposure for the lender if you stop paying and they have to sell the home to recover their money. PMI offsets that risk.
What PMI does not do: it doesn’t pay your mortgage if you lose your job, and it doesn’t protect your credit or equity if you default. It exists entirely for the lender’s benefit. You pay for it; they benefit from it. This is why borrowers resent it — understandably.
How Much Does PMI Cost?
PMI typically costs 0.5% to 1.5% of the loan amount per year, depending primarily on your credit score and down payment size.
| Down Payment | Credit Score | Annual PMI Rate | Monthly PMI (on $360K loan) |
|---|---|---|---|
| 5% | 760+ | ~0.5% | ~$150 |
| 5% | 700–759 | ~0.7% | ~$210 |
| 5% | 660–699 | ~1.0% | ~$300 |
| 10% | 760+ | ~0.3% | ~$90 |
| 10% | 700–759 | ~0.5% | ~$150 |
| 15% | 760+ | ~0.2% | ~$60 |
On a $400,000 home with 10% down ($40,000), a borrower with a 720 credit score pays roughly $150/month in PMI — $1,800/year — until the loan reaches 80% of the original value.
PMI is paid monthly as part of your PITI payment and collected through escrow.
When Does PMI Go Away?
This is where many homeowners leave money on the table by not knowing their rights.
Federal law (Homeowners Protection Act) gives you two protections:
1. You can request cancellation at 80% LTV. Once your loan balance drops to 80% of the original purchase price — through payments, extra principal, or a combination — you can formally request PMI cancellation. Your lender must honor this request if you have a good payment history and the home hasn’t declined in value. You may need a new appraisal (at your cost, typically $300–$500) to confirm value.
2. Automatic cancellation at 78% LTV. Even if you never request it, your lender is legally required to cancel PMI when your balance reaches 78% of the original purchase price based on your amortization schedule. This is calculated from your original loan amount and purchase price — not current market value.
How long does that take? On a $400,000 purchase with 10% down at 6.75%:
- Loan starts at $360,000 (90% LTV)
- 80% LTV threshold: $320,000
- Time to reach $320,000 via normal payments alone: approximately 8 years
That’s 8 years of PMI at $150/month = roughly $14,400 paid before automatic cancellation.
Faster route: If home values appreciate significantly, you may reach 80% LTV much sooner. In that case, you request a new appraisal, demonstrate 80% LTV based on current value, and request cancellation — without waiting for the amortization schedule to catch up.
PMI vs. FHA Mortgage Insurance Premium (MIP)
Borrowers comparing conventional loans with FHA loans need to understand a critical difference: FHA mortgage insurance works very differently from PMI, and often costs more in the long run.
| Conventional PMI | FHA MIP | |
|---|---|---|
| When required | Down payment < 20% | All FHA loans |
| Upfront cost | None | 1.75% of loan (financed) |
| Annual cost | 0.2%–1.5% | 0.55%–1.05% |
| Duration | Until 80% LTV | Life of loan (if < 10% down) |
| Cancellable? | Yes, at 80% LTV | Only by refinancing |
On an FHA loan with less than 10% down, MIP lasts forever. The only exit is refinancing into a conventional loan once you have 20% equity. Factor this into your comparison when choosing between FHA and conventional.
5 Ways to Avoid or Reduce PMI
1. Put down 20%. The cleanest solution, but not always realistic. On a $400,000 home, 20% is $80,000 — a significant barrier for most first-time buyers.
2. Piggyback loan (80/10/10). Take a first mortgage for 80% of the purchase price, a second mortgage (home equity loan or HELOC) for 10%, and put down 10% in cash. The first mortgage avoids PMI because its LTV is exactly 80%. The second loan carries a higher rate, but the total cost may be less than PMI depending on current rates.
3. Lender-paid PMI (LPMI). The lender covers PMI in exchange for a slightly higher interest rate on your loan. There’s no monthly PMI line item, but your rate is higher — permanently, for the life of the loan (or until you refinance). LPMI makes sense if you plan to sell or refinance before you’d reach 20% equity anyway.
4. VA loan. Veterans, active-duty service members, and eligible surviving spouses can use VA loans, which carry no PMI requirement — ever, at any down payment level, including zero down. The VA funding fee applies, but for most borrowers it’s significantly cheaper than years of PMI payments.
5. Make a larger down payment. Even moving from 5% to 10% down substantially reduces PMI rates. If you’re close to a tier threshold, it’s worth crunching the numbers on whether a slightly larger down payment eliminates or significantly reduces PMI.
The Real Question: Should You Avoid PMI at All Costs?
Not necessarily — and this is where the conventional wisdom misleads buyers.
Consider two scenarios for a $400,000 home purchase:
Scenario A: Save until you have 20% down ($80,000). Buy in 2 years.
Scenario B: Buy now with 10% down ($40,000). Pay $150/month in PMI.
If home values increase 5% per year during those 2 years, the $400,000 home becomes a $441,000 home. The appreciation you missed: $41,000. The PMI you’d pay over 2 years: $3,600.
In a rising market, waiting to avoid PMI can cost more than PMI itself. The math favors buying sooner and paying PMI in many (not all) market conditions.
The honest answer depends on your local market appreciation rate, your opportunity cost for the additional down payment savings, and how long you’ll hold the home. In flat or declining markets, waiting to put down 20% looks better. In appreciating markets, paying PMI to enter earlier often wins.
How to Get PMI Removed Once You Have It
Step 1: Check your loan servicer’s process. Most servicers have an online form or phone process for PMI cancellation requests.
Step 2: Confirm you meet the requirements:
- Your balance is at or below 80% of the original purchase price, OR
- You have evidence (new appraisal) that your current LTV is 80% or below based on market value
- You have a satisfactory payment history (no 30-day lates in the past 12 months, no 60-day lates in the past 24 months)
- The property value hasn’t declined
Step 3: Order an appraisal if using current market value. Cost: $300–$500. Worth it if appreciation has been significant.
Step 4: Submit the written request. Your servicer must respond within 30 days and cancel PMI if requirements are met.
Don’t wait for automatic cancellation if you’ve built equity through appreciation. Automatic cancellation at 78% is based on the original amortization schedule — it ignores home value increases entirely. Proactive cancellation via appraisal can save you years of unnecessary PMI payments.
Frequently Asked Questions
Is PMI tax deductible? PMI deductibility has been inconsistent — Congress has allowed it in some years and not others. As of 2026, consult a tax advisor for the current status. Don’t build your budget around PMI deductibility as a guaranteed benefit.
Can I negotiate PMI rates? Not directly — PMI is priced by the mortgage insurance company, not your lender. However, your credit score and down payment are the main variables. Improving your credit score before closing can reduce your PMI rate. Shopping multiple lenders matters less for PMI specifically, but lenders use different MI providers and rates vary slightly.
Does PMI affect my ability to qualify? Yes. PMI is included in your PITI payment, which affects your front-end debt-to-income ratio. A higher PMI payment means you qualify for a smaller loan at the same income. This is another argument for making a larger down payment if you’re near a borrowing limit.
What if my home value drops below the purchase price? If your home declines in value, reaching 80% LTV based on current market value becomes harder. Automatic cancellation still happens at 78% of the original purchase price regardless of current value — but you cannot request early cancellation based on current value if the home has depreciated.
The Bottom Line
PMI is a cost of buying with less than 20% down, not a penalty for making a bad decision. In many cases, buying sooner with PMI is smarter than waiting until you can put 20% down — especially in appreciating markets.
Know your cancellation rights, track your equity, and request removal the moment you hit 80% LTV. Don’t wait for automatic cancellation at 78% — you may leave a year or more of unnecessary payments on the table.
