A borrower I worked with early in my career was paying $187 per month in private mortgage insurance on a conventional loan she had taken out three years earlier. Her home had appreciated significantly since closing, and she was convinced she had enough equity to eliminate it. She was right. But she did not know that she had two options: pay $500 for a fresh appraisal and ask her lender to cancel PMI administratively, or refinance into a brand new loan and get a better interest rate in the process. She almost reflexively chose the refi without running the numbers.

That kind of decision, made without a clear break-even calculation, costs borrowers real money. In her case, the appraisal-only route saved her roughly $4,800 in closing costs because her rate was already good. But if your current rate is above today’s market, refinancing can eliminate PMI and lower your payment at the same time, making it one of the best financial moves available to a homeowner.

This guide walks through every scenario so you can make the same call with full information.

What PMI Is and Why Lenders Require It

Private mortgage insurance protects the lender, not you, if you default on your loan. Lenders require it when you put less than 20% down on a conventional mortgage because loans above 80% loan-to-value carry meaningfully higher default risk. The cost varies based on your credit score, loan size, and down payment, but for most borrowers it falls between 0.5% and 1.5% of the loan amount per year.

On a $325,000 loan, that translates to roughly $135 to $406 per month. It is pure overhead with no equity-building component. The single best thing you can do financially once you cross the 80% LTV threshold is eliminate it.

PMI on a conventional loan is not permanent, which is the critical distinction from FHA mortgage insurance. There are three ways it can go away:

  1. Automatic cancellation when your loan balance reaches 78% LTV (based on the original purchase price or appraised value at origination, per the Homeowners Protection Act of 1998).
  2. Requested cancellation when you can demonstrate your balance is at or below 80% LTV, either through scheduled amortization or a new appraisal.
  3. Refinancing into a new loan with at least 20% equity.

Most borrowers do not realize they can request cancellation. They wait for the automatic 78% milestone, which on a 30-year loan with a 5% down payment can take 11 to 12 years at a moderate interest rate.

The Automatic Cancellation Rules (Federal Law)

The Homeowners Protection Act mandates that lenders automatically cancel PMI when your loan balance reaches 78% of the original value of the property. This is calculated based on the original appraised value at closing, not your home’s current market value. If you paid $350,000 and put 5% down, the starting loan balance was $332,500 and automatic cancellation kicks in when you pay it down to $273,000 (78% of $350,000).

The law also requires your lender to tell you the specific date when automatic cancellation will occur. Check your mortgage statement or call your servicer and ask for the PMI cancellation date.

At 80% LTV based on original value, you can request cancellation in writing, but the lender can require: proof of a good payment history (no 30-day lates in the past 12 months, no 60-day lates in the past 24 months), and certification that the property value has not declined. Some lenders also require a new appraisal even at the scheduled 80% mark if they have reason to believe the home has lost value.

The Appraisal-Only Route: No Refi Needed

Here is what many borrowers do not know: if your home has appreciated since purchase, you may be able to cancel PMI without refinancing at all. You simply order a new appraisal (at your expense, typically $400 to $650), demonstrate to your lender that your current loan balance is 80% or less of the new appraised value, and request PMI removal in writing.

Most lenders require that you have been in the loan for at least 24 months before they will accept a new appraisal for PMI cancellation purposes. Some will do it at 12 months. You typically cannot do it in the first year regardless of appreciation.

The math is simple: if your $300,000 home is now appraised at $375,000, your $240,000 loan balance is exactly 64% LTV. You are well under 80% and should have no trouble getting PMI cancelled with a letter to your servicer accompanied by the appraisal.

This approach makes sense when your interest rate is already at or near today’s market rates. Paying $500 to $650 for an appraisal and eliminating $150 per month in PMI breaks even in about 3 to 4 months. A full refinance with $5,000 to $8,000 in closing costs takes much longer to pay off.

When Refinancing to Remove PMI Makes More Sense

The appraisal-only route wins on cost when your rate is competitive. But refinancing to remove PMI is the smarter play in three specific situations:

Your current rate is above market. If you took your loan out at 7.25% and current conforming rates are 5.875% to 6.25%, refinancing accomplishes two things simultaneously: you lock in a lower rate and eliminate PMI. The savings stack.

You have an FHA loan (see the MIP trap below). FHA mortgage insurance has completely different rules and often cannot be cancelled without a full refinance. The appraisal-only shortcut does not apply.

Your loan is young and the scheduled amortization will take too long. On a $350,000 loan at 7% with 5% down, you will not hit 80% LTV through payments alone for approximately 9 years. If your home has appreciated to $440,000, refinancing now at 6.0% with 20% equity position eliminates $200 per month in PMI and lowers your rate by 100 basis points.

The FHA MIP Trap: This Is Critical

FHA loans do not have PMI. They have mortgage insurance premium (MIP), and it works completely differently. If you took out an FHA loan after June 3, 2013, and your original loan-to-value was above 90%, you pay MIP for the entire life of the loan. There is no cancellation. No amount of equity growth, no appraisal, no payment of the balance to 78% will make it go away as long as you have an FHA loan.

The only way to eliminate FHA MIP in this scenario is to refinance into a conventional loan. Given that FHA rates typically run 5.5% to 7.25% in 2026 and conventional rates for borrowers with good credit run 5.75% to 7.0%, the rate difference may be modest, but eliminating MIP often justifies the closing costs on its own.

The FHA MIP on a $300,000 loan at the standard 0.55% annual rate (for loans over 15 years with LTV above 90%) costs $137.50 per month or $1,650 per year. Over the remaining life of a 30-year loan taken out 3 years ago, that is $37,125 in total MIP you will pay unless you refinance out.

There is one exception: if your FHA loan’s original LTV was 90% or below at closing, MIP cancels at 11 years. If you put exactly 10% down, you are in this category.

Running the Break-Even Math

Use the RobotRefi break-even calculator to model your exact situation, but here is the framework:

ScenarioPMI/MIP MonthlyRefi CostBreak-Even
$325k loan, $65/mo PMI, $5,500 refi$65$5,50085 months (7 years)
$325k loan, $65/mo PMI, $500 appraisal$65$5008 months
$350k FHA, $160/mo MIP, $6,000 refi$160$6,00038 months (3.2 years)
$350k FHA, $160/mo MIP, rate drops 1%$160 + $350/mo rate savings$6,00012 months

The last row illustrates the stacking benefit. When you eliminate MIP and lower your rate simultaneously, the break-even compresses dramatically.

Be sure to factor in the rate you are refinancing into. If you are moving from 6.5% to 6.1% on a $325,000 loan, the rate-only savings is about $83 per month. Add $65 in PMI elimination and your monthly improvement is $148. At $5,500 in closing costs, break-even is 37 months, or just over 3 years. If you plan to stay in the home for 5 or more years, that is a clear win.

What to Expect From the Refi Process When PMI Is the Goal

The process is standard: application, appraisal, underwriting, closing. The lender will order a new appraisal to confirm current market value. This is required even if you have a recent independent appraisal you commissioned yourself.

A few things to watch for:

  • Order of operations matters. Get your home in good shape before the appraisal. Comparable sales in your neighborhood drive the number, but appraiser condition adjustments can cut value by $5,000 to $15,000 for obvious deferred maintenance.

  • LTV at the new loan matters. If the new loan is at or below 80% LTV, no PMI on the new conventional loan. If your appraisal comes in lower than expected and you land at 82% LTV, you will pay PMI on the new loan too, though often at a lower rate than the original loan if your credit has improved.

  • Closing costs vs. lender credits. If eliminating PMI rather than rate savings is the primary goal, it can make sense to take a slightly higher rate in exchange for lender credits covering most closing costs. A “no-cost refi” in this context means faster break-even because your out-of-pocket is near zero.

Scenarios Where You Should Wait and Not Refi

Not every situation calls for action. Wait if:

  • You are within 12 to 18 months of the scheduled 80% LTV mark via normal amortization and your home has not appreciated substantially. Spending $5,500 to save 18 months of PMI payments is often not worth it.

  • Rates have moved significantly higher than your current rate. If you are locked in at 5.5% and current rates are 7.0%, refinancing to eliminate $80 per month in PMI while raising your rate by 150 basis points would add hundreds more to your payment.

  • You plan to sell within 2 years. The closing costs may not recoup before you close and walk away.

  • Your credit has declined since the original loan. You might face worse pricing on the new loan, narrowing or eliminating the benefit.

How the Lender Cancellation Request Works (No Refi Needed)

If your home has appreciated and you want to go the appraisal-only route:

  1. Call your loan servicer and ask for their PMI cancellation request process. Get it in writing.
  2. Confirm the loan seasoning requirement (usually 12 to 24 months from origination).
  3. Order an appraisal from an appraiser approved or accepted by your lender. Do not use just anyone. Some servicers require their own panel appraiser.
  4. Submit a formal written request, the appraisal report, and any required payment history documentation.
  5. The servicer has 30 days to respond under federal law.

If the appraisal supports 80% LTV or below and your payment history is clean, PMI cancellation is mandatory. They cannot deny a valid request.

ROBO’s Bottom Line

Eliminating PMI is one of the clearest financial wins available to a homeowner, but the right tool depends on your situation. If your rate is good and your home has appreciated, the $500 appraisal route is usually the right call. If you have an FHA loan post-2013 with more than 10% down at origination, refinancing into a conventional loan is almost certainly worth running the numbers on. If your rate is meaningfully above today’s market and you have enough equity, a full refinance that eliminates PMI and lowers your rate simultaneously can shave hundreds off your monthly payment with a break-even under 3 years.
