Millions of American homeowners are quietly paying hundreds of dollars extra every month without realizing they can make it stop.
It's called private mortgage insurance, or PMI, and it typically gets tacked onto conventional loans when a buyer puts down less than 20 percent.
The charge isn't huge on its own, but it adds up fast—often $100 to $300 a month that does nothing for your principal balance.
Here's the catch: PMI isn't permanent, but it also doesn't disappear automatically in every situation.
You usually have to ask for it to be removed, and the rules depend on your loan type, your payment history, and how much equity you've built.
For conventional loans backed by Fannie Mae and Freddie Mac, you have two paths to removal.
The first is a borrower-requested cancellation, which you can pursue once your loan balance drops to 80 percent of the home's original value—based on the original purchase price or the appraised value at closing, not today's market.
The second is automatic termination, which kicks in when you hit 78 percent of that original value based on your normal payment schedule.
That one happens without you lifting a finger.
The 80 percent rule trips people up because it's based on the original value, not what your home is worth now.
If you bought at $400,000 with 10 percent down, you're waiting until the balance hits $320,000—even if your home is now worth $500,000.
In that case, a new appraisal can help you argue for earlier removal, but your lender has to agree to use it.
There are a few boxes you have to check first.
Your payment history needs to be clean, typically no 30-day late payments in the last 12 months and none in the past 24 months for the automatic path.
You'll also need to be current on your loan, and if you have a second mortgage or home equity line, that can complicate things.
If you put down less than 10 percent, that mortgage insurance premium usually lasts the life of the loan unless you refinance into a conventional product.
With 10 percent or more down, it drops off after 11 years.
That's why so many FHA borrowers eventually look at a refi once they've built equity.
On a $350,000 loan, PMI can run $150 to $250 a month—roughly $1,800 to $3,000 a year.
And unlike interest, none of it builds equity or comes back to you at closing.
If you think you're close, call your loan servicer—not the original lender, since many loans get sold—and ask for your current loan-to-value ratio and the specific requirements to cancel.
Put the request in writing if they stall.
Under federal law, servicers have to give you a clear answer and a timeline once you meet the conditions.
One more thing worth checking: if your home value has jumped since you bought, a fresh appraisal might get you under the threshold years earlier.
It costs a few hundred dollars, but it can pay for itself in a couple of months.
If you're paying PMI and you've been making payments for a while, you may be handing your lender free money every month.
