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 never learn the rules for getting rid of it.
Lenders require it because a borrower with a small down payment is statistically riskier, and the insurance protects the lender, not you, if you default.
Depending on your loan size and credit profile, that added premium can run anywhere from $30 to more than $200 a month.
Here's the part most people miss: you don't have to wait for your lender to bring it up.
Under the Homeowners Protection Act, a federal law passed in 1998, servicers must automatically cancel PMI once your loan balance drops to 78 percent of the home's original value, based on your normal payment schedule.
Once you hit 80 percent loan-to-value, you can formally request cancellation in writing.
The difference between 80 and 78 percent can be several months of premiums, and that's real money back in your pocket.
The trick is that "80 percent" isn't always about what you owe versus what you paid.
If your home has appreciated, you can sometimes get there faster with a new appraisal.
Lenders generally require a broker or appraiser they approve, and you'll likely cover the cost, often $400 to $700.
Run the math first, because the appraisal fee only makes sense if the savings outrun it.
Most servicers want you current on payments, with a decent payment history, before they'll approve a borrower-initiated request.
You'll also typically need to be at least two years into the loan, though some programs allow exceptions.
A rise in your home's value alone won't trigger automatic cancellation.
The automatic 78 percent threshold is based on the original amortization schedule, not a hot housing market.
If you've been paying extra toward principal, you may reach that mark sooner, so keep an eye on your statement.
If you're not sure where you stand, call your servicer and ask for your current loan-to-value ratio and the specific requirements on your loan.
Some loans, like FHA mortgages, follow different rules and may require refinancing to shed the insurance, which is a separate decision.
One more thing worth checking: if you bought during the pandemic-era rate lows, a refinance might kill PMI and lower your rate at the same time.
But if you're sitting on a 3 percent mortgage now, refinancing just to drop insurance could backfire badly.
Our take: PMI removal is one of the few money moves that requires no market timing and no luck.
It's just paperwork, a phone call, and knowing the 80 percent rule.
Final Thoughts
If you've been paying it for years without checking, that's likely a few thousand dollars you've handed over for nothing.
