Millions of American homeowners are quietly paying hundreds of dollars extra every month without realizing they may not have to.
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 catch is that many borrowers keep paying it long after they've earned the right to drop it.
It protects the lender if you default, and it usually costs between 0.3 percent and 1.5 percent of your loan amount each year.
On a $350,000 mortgage, that can run $100 to $400 a month, money that does nothing for your equity or your credit score.
The good news is that federal law gives you a clear path out.
Under the Homeowners Protection Act, your lender must automatically cancel PMI once you reach 22 percent equity based on the original home value and payment schedule.
You can request cancellation once you hit 20 percent equity, and that's where most people leave money on the table.
If your home has appreciated, you may be able to use a new appraisal to prove you've crossed that threshold faster than your original amortization schedule suggests.
Here's what the process usually looks like.
First, check your loan statements or call your servicer to confirm you actually have PMI and what your current balance is.
Then ask, in writing, what their specific requirements are for removal, because every lender sets its own rules.
Most servicers want a few things: a good payment history, often no 30-day late payments in the past 12 to 24 months, proof of at least 20 percent equity, and sometimes a new appraisal you'll pay for out of pocket.
Appraisals commonly run $400 to $700, so it's worth running the math before you order one.
If your loan is backed by FHA, the rules are different and often stricter.
FHA mortgage insurance premiums can last the life of the loan if you put down less than 10 percent, which is why some homeowners refinance into a conventional loan to escape them.
One more option worth knowing: if you've built significant equity and rates make sense, a refinance can eliminate PMI entirely.
Just make sure the closing costs and new rate don't wipe out your monthly savings.
The bottom line is that PMI removal isn't automatic for most people at the 20 percent mark.
It requires a phone call, some paperwork, and occasionally a few hundred dollars for an appraisal.
But the payoff can be real, often freeing up $1,200 to $4,800 a year for families who've been overpaying for months or years.
Our take: this is one of the easiest wins in household budgeting, and it's absurd that borrowers have to chase it down themselves.
Set a reminder to check your equity every year, and don't assume your lender will do you any favors.

A 20-minute phone call could hand you back more than most people save by clipping coupons all year.
