Your Assessment Comes With a 30-Day Clock to Fight It. Three in Four Homeowners Never Start It.

If your mortgage payment went up this year and your rate didn’t move, the culprit is sitting in your escrow account. Part of it is insurance. The other part is a number your county assigned to your house, and unlike almost every other bill you get, that one comes with a window to argue.

Almost nobody opens it.

Sixty-four percent of homeowners were surprised or shocked by their most recent property tax bill, up from 59% a year earlier. Seventy-four percent have never appealed one. That’s from a survey of 2,500 homeowners across all 50 states and Washington, D.C., run in March and published this month.

Here’s the part that should annoy you. Of the people who’ve never appealed, 57% didn’t know they had the right to.

Your county isn’t hiding it. It prints the appeal right on the notice, in the same tone and typeface a gym uses for its cancellation policy. Seventy-six percent of homeowners said their property taxes ran past what they’d budgeted, up 10 points in a single year, and 40% have thought about moving over the bills. Almost none of them filled out the form.

So what happens to the ones who do?

“Somewhere between 3% and 5% of homeowners actually file an appeal, and of those, between 30% and 50% win some kind of reduction,” says Pete Sepp, president of the National Taxpayers Union.

Translation: the line is very short, and something like a third to half of the people standing in it get paid. Realtor.com analysis found more than 40% of properties could save $100 or more a year, with median savings around $539.

Five hundred thirty-nine dollars is about $45 a month off your escrow payment. It repeats every year until the next reassessment. That’s real money for an afternoon of work, and it’s the rare housing cost you can actually push back on.

Now the timing, because this is where people lose it by default. “Typically, when you get the thing in the mail, you have between 30 and 60 days to either give notice or file your appeal,” Sepp says. Miss it and you wait a year.

Do this in order. Pull your property record card off the assessor’s website and read it like it belongs to a stranger. Check the square footage, the bedroom and bathroom count, the garage, the finished basement. Assessors work from records, not visits, and records carry old permits and other people’s renovations.

Then pull the assessed values of four or five similar homes near yours and compare them per square foot. A gap of 10% or more is your case, and you make it on a form, not in a courtroom.

Then run your payment with the corrected number on our mortgage calculator so you know what you’re actually fighting for, and see the rest at our mortgages hub.

The assessor already made a guess about your house. They made it from a file, not from your kitchen.
