PMI (private mortgage insurance) is the line item on your monthly payment that protects the lender if you default. It protects the lender, not you, and it can quietly cost $200 to $400 every month for 7 to 10 years if you do nothing about it. On a $400,000 loan, that is $24,000 to $48,000 of money you can stop paying the moment you cross a specific loan-to-value threshold.

There are four paths to removing PMI, and most borrowers only know about the slowest one. Here is the full playbook: the legal thresholds, the letter you send to your servicer, the appraisal trick that works in rising markets, and the refinance breakeven math that decides whether the faster path is actually worth it.

What PMI costs and why it matters

PMI is priced as a percentage of your original loan amount, typically 0.3 percent to 1.5 percent per year, based on your credit score and down payment. A borrower with a 720 FICO and 10 percent down is looking at roughly 0.5 to 0.8 percent annually. A borrower with a 660 FICO and 5 percent down can be paying 1.0 to 1.5 percent.

On a $400,000 loan at 0.8 percent PMI, that works out to $3,200 per year or $267 per month. If you follow the standard amortization schedule and PMI terminates automatically, you are paying that for roughly 7 to 10 years. Actively removing PMI at year 3 instead of year 8 saves roughly $16,000 over the life of the loan. This is why understanding the four cancellation paths is worth 30 minutes of reading.

The LTV math you need to know

Every PMI rule is expressed in loan-to-value (LTV) ratio: your remaining loan balance divided by the property value, expressed as a percentage. Two thresholds matter.

The two numbers

Key LTV thresholds

  • 80 percent LTV. The threshold at which you can request PMI cancellation in writing. Requires you to be current, have no second liens, and property value to have not declined.
  • 78 percent LTV. The threshold at which the lender must automatically terminate PMI under the Homeowners Protection Act (HPA), based on the original amortization schedule.

Notice the 2-point gap. If you wait for automatic termination at 78 percent, you pay PMI for an extra 18 to 24 months compared to a borrower who proactively requests cancellation at 80 percent. The automatic path is designed so that even borrowers who do nothing eventually stop paying. You should do something.

Path 1: Automatic termination at 78% LTV

The Homeowners Protection Act requires your servicer to automatically terminate PMI when your scheduled LTV (based on the original amortization schedule and the original property value) hits 78 percent, as long as your payments are current. You do not have to request it, sign anything, or pay for an appraisal. It just stops appearing on your statement.

The catch: it is scheduled, not calculated against current value. If you started at 90 percent LTV, the amortization schedule might not hit 78 percent until year 10 or year 11 of a 30-year loan. Even if your home has doubled in value, automatic termination uses the original appraisal. This path is the floor, not the goal.

Path 2: Borrower-requested cancellation at 80% LTV

Under HPA, you can request cancellation in writing once your LTV reaches 80 percent. Two ways to calculate that LTV:

  • Original value method. Use the original purchase price (or original appraised value at closing, whichever is lower) as the denominator. Just watch the amortization schedule for the month your balance drops below 80 percent of that number.
  • Current value method. Order a new appraisal to capture market appreciation. Use the new appraised value as the denominator.

The lender must grant the request if three conditions are met:

  1. You are current on payments (no 30-day late in the past 12 months, no 60-day late in the past 24 months).
  2. You have no second liens on the property.
  3. The property value has not declined below the original value (or, if using current value, the appraisal supports the number).

The request is a letter to your loan servicer. The exact wording matters less than the content. Include your loan number, property address, a clear request to cancel PMI, and your calculation showing LTV is at or below 80 percent. If you are using current value, include language offering to pay for an appraisal by a lender-approved appraiser.

Path 3: New appraisal in a rising market

This is the path most borrowers miss, and it is the single highest-leverage move if your market has appreciated. Say you bought in 2022 at $400,000 with 10 percent down. Your loan was $360,000 (90 percent LTV). By 2026, you have paid the balance down to $340,000, and your market has appreciated so the home is now worth $475,000.

On the original value ($400,000), your LTV is still $340,000 / $400,000 = 85 percent. No cancellation.

On the current value ($475,000), your LTV is $340,000 / $475,000 = 72 percent. Well below 80 percent.

The fix is a broker's price opinion or full appraisal (your servicer will specify which they accept). Cost is typically $150 to $650. If the appraisal comes in at or above the value you need, you submit it with your cancellation request letter.

Two rules to know before you spend the appraisal money:

  • Most lenders require at least 2 years of payment history before they will consider value-based cancellation, or 5 years if you want to hit 75 percent LTV using appreciation alone.
  • The appraisal must be ordered through the lender's approved appraiser list. Do not order your own appraisal hoping they will accept it. They will not.

Before you spend the money, pull comps yourself on Zillow, Redfin, and Realtor.com. Look at closed sales (not listings) within 1 mile and 6 months. If recent comparable closed sales clearly support the value you need, the appraisal is a good bet. If comps are borderline, wait another 6 to 12 months.

Path 4: Refinance into a new loan

If your current loan is an FHA loan (where MIP cannot be removed without refinancing) or if you have a conventional loan but the above paths are not available for another 3 to 5 years, refinancing into a new conventional loan at 80 percent or less LTV eliminates PMI in one move.

The math is a breakeven problem. Run these numbers:

  • Monthly PMI savings. Current PMI payment, typically $150 to $400.
  • Interest rate change. If you are refinancing from a 3.5 percent rate into a 6.5 percent rate just to drop PMI, the higher interest almost always exceeds the PMI savings. Refinance for PMI alone only works when new rates are at or below your current rate.
  • Refinance closing costs. Typically 2 to 3 percent of the new loan, or $6,000 to $12,000 on a $400,000 refinance. Some of this can be rolled into the new loan, but that offsets the LTV you gained.
  • Breakeven months. Closing costs divided by monthly savings = months to recoup. Under 36 months is a good refinance. Over 60 months is questionable unless you plan to own the home for at least 10 more years.

FHA borrowers face a specific version of this math. FHA mortgage insurance premium (MIP) is required for the life of the loan on most post-2013 FHA mortgages with less than 10 percent down. The only way off is a refinance. Once you have 20 percent equity, a conventional refinance eliminates MIP entirely, often with a meaningful rate improvement depending on when you originated.

The cancellation letter: what to send

The letter should be short, on paper (certified mail with return receipt), and include these elements:

  • Your full legal name and loan number
  • Property address
  • An explicit request: "I am writing to request cancellation of Private Mortgage Insurance on the above loan."
  • Your LTV calculation with current balance and value used
  • A statement that payments are current and there are no second liens
  • If using current value: an offer to pay for an appraisal by a lender-approved appraiser
  • Your contact information and request for written confirmation

Mail it certified with return receipt. The servicer has 30 days to respond. If they deny the request, they must tell you why in writing. Common reasons: payment history issue, second lien you forgot about, property value not supporting current-value method. Fix the issue and resubmit.

Prepaying principal to accelerate the clock

If you are close to 80 percent LTV but not quite there, prepaying principal can tip you over the line. Every dollar you pay on principal (beyond your scheduled payment) reduces the loan balance immediately, which reduces LTV immediately, which can bring the cancellation date forward by months or years.

Example: $400,000 home, $320,000 loan balance. To hit 80 percent LTV on original value, you need to owe $320,000 or less. You are already there. Submit the request today.

Example: $400,000 home, $340,000 balance. $20,000 lump-sum prepayment drops you to $320,000 and triggers eligibility. If your PMI is $250 per month, that $20,000 pays itself back in 6.6 years of saved PMI payments (or faster when you factor in the absence of interest on the $20,000 you prepaid).

Before prepaying: confirm your loan has no prepayment penalty (rare on modern conventional loans, more common on some adjustable-rate and non-QM loans).

The bottom line

PMI cancellation is one of the highest-ROI hours of work a homeowner can do in the first 3 to 5 years of ownership. Check your loan statement for your current LTV, pull comps for current value, and decide which of the four paths fits your situation. Most borrowers who actively manage this save $10,000 to $25,000 compared to letting automatic termination do it for them.
