Private mortgage insurance exists to protect the lender, not you. When you put less than 20% down on a conventional mortgage, the lender faces more risk — and they pass that cost to you as a monthly PMI premium. On a $400,000 loan, PMI at 0.75% costs $250/month, or $3,000 per year. Multiplied over the 7–10 years many borrowers pay it, the total runs well into five figures. Understanding your removal options — and acting proactively — can save thousands.
The Two Federal Thresholds That Govern PMI
The Homeowners Protection Act of 1998 (HPA) creates two mandatory milestones for conventional loans:
- 80% LTV — your right to request cancellation. When your loan balance reaches 80% of the original purchase price or appraised value, you may send a written request to your servicer. The servicer can require you to have a good payment history and to demonstrate that the home's value hasn't declined below the original figure.
- 78% LTV — automatic cancellation required. When your balance reaches 78% of the original value, the HPA requires your servicer to cancel PMI automatically — as long as you're current on payments. This is based on the original amortization schedule, regardless of any extra payments you've made.
Both thresholds use the original value — the purchase price or original appraised value, whichever was lower at the time the loan closed. Even if your home has tripled in value, the automatic cancellation calculation doesn't update. (That's where Path 3 below becomes valuable.)
Path 1: Wait for Automatic Cancellation (78% LTV)
The simplest approach: do nothing and let the amortization schedule reach 78%. On a $350,000 loan at 7% interest with 3.5% down ($337,750 loan), automatic cancellation occurs approximately in year 11 under the scheduled payment alone. That's 11 years of PMI — roughly $25,000–$40,000 depending on your rate. And it's entirely legal.
When it makes sense: If you have a low PMI rate (under 0.3%) or don't have the energy to manage the process, automatic cancellation is fine. The servicer must cancel without you asking.
Path 2: Request Cancellation at 80% LTV
You can shave 2+ years off Path 1 by sending a written cancellation request when your balance reaches 80% of the original value. The savings gap between 80% and 78% seems small, but adds up fast: on a $1,800/year PMI bill, catching two years early saves $3,600.
What lenders typically require:
- Written request (see template below)
- Current on payments — no 30-day late in the past 12 months, no 60-day late in the past 24 months
- Evidence that the home's value hasn't declined (an appraisal or AVM — ask your servicer first; many do AVM at no cost)
- No subordinate liens (second mortgages must be disclosed)
After receiving your request, the servicer has 30 days to respond. Use the PMI removal calculator to find your exact month and how much you save vs waiting.
Path 3: Early Removal Based on Home Appreciation
If your home has appreciated, you may qualify to remove PMI significantly earlier — even if your balance hasn't yet reached 80% of the purchase price — because a new appraisal sets a new value basis for the LTV calculation.
Example: You paid $400,000 three years ago with 10% down ($360,000 loan). Your balance is now approximately $344,000. That's 86% LTV on the original value — PMI still required. But if the home is now worth $480,000, your LTV on the new value is $344,000 ÷ $480,000 = 71.7%. Well under 80%. A new appraisal triggers removal.
Lender-specific rules apply:
- Most lenders require the loan to be at least 2 years old
- Some lenders require 25% equity (75% LTV) if the loan is less than 5 years old
- A full appraisal (not just an AVM) is almost always required — typically $350–$600
- Check your servicer's guidelines before ordering an appraisal; using a lender-approved appraiser prevents disputes
In many markets, homeowners who purchased 2016–2023 have seen 30%–60% appreciation. If that describes you, Path 3 likely saves the most money fastest.
| Scenario | Original Value | Current Balance | Appraised Value | Current LTV | Can Remove? |
|---|---|---|---|---|---|
| 3 years in, flat market | $400,000 | $344,000 | $405,000 | 85% | Not yet |
| 3 years in, 20% appreciation | $400,000 | $344,000 | $480,000 | 71.7% | Yes |
| 5 years in, 10% appreciation | $400,000 | $332,000 | $440,000 | 75.5% | Yes |
| 7 years in, on schedule | $400,000 | $318,000 | $400,000 | 79.5% | Yes (request) |
Path 4: Refinance to Eliminate PMI
If you can refinance to a new loan with 20%+ equity at close, PMI doesn't apply to the new loan. This makes sense when you can simultaneously capture a lower rate — the break-even on closing costs becomes more reasonable when you're also lowering your monthly interest bill.
Refinancing solely to remove PMI rarely works unless you're paying very high PMI (over $200/month) and your home has appreciated enough that you have strong equity. With typical closing costs of 2%–4% of the loan amount and refinance rates potentially higher than your existing rate, the math often doesn't pencil out versus simply requesting cancellation.
When refinancing to remove PMI makes sense:
- You can also capture a rate that is 0.5%+ lower than your current rate
- You have 20%+ equity based on the home's current value
- You expect to stay in the home long enough to recoup closing costs (break-even typically 2–3 years)
How to Write the PMI Cancellation Request
No official form is required. A simple letter to your servicer's PMI department works. Include: your name, loan number, property address, a statement that you are requesting PMI cancellation under the Homeowners Protection Act, confirmation that you are current on payments, and your contact information. Send certified mail, return receipt requested, and keep a copy.
Use the PMI removal calculator to find the exact month you hit 80% LTV and how much you save versus waiting. Once you've removed PMI, that monthly savings can accelerate mortgage payoff or go toward building a down payment for a future move.
