The county notice arrives in a window envelope with a number on it and no explanation. Most of us read the number, mutter something, and file it with the insurance papers.

That is the whole transaction. One reading, no reply.

The National Taxpayers Union Foundation estimates that 30 to 60 percent of American homes are assessed above what they are worth. A 2026 survey found 74% of homeowners have never once appealed.

Fewer than one in twenty files in any given year. Hold that five percent, because the next three figures make it look strange.

 

A coin-flip chance at a ten percent reduction. On a bill that rises every year and never goes away. And nineteen of twenty of us decline the flip.

The easiest wins have nothing to do with value. Every county keeps a property record card listing your square footage, bedroom count, lot size and condition. Request it, which is free, and read every line against the house you live in.

A bathroom that was never built. A basement counted as finished. Square footage from a previous owner’s extension. Corrections rather than disputes, and assessors grant them without a hearing.

Now the part that is specific to our age, and it is a matter of order.

Many states offer people past sixty-five a freeze. It locks your assessed value, or your tax dollars, at the level of the year you qualify. A genuine gift, and a trap. Whatever number you are sitting on becomes permanent.

Appeal first. Freeze second. Do it the other way round and you have locked in an overassessment for the rest of your life in that house.

One envelope, read down the list.

A whole industry has grown in the space between the people who could file and the people who do.

Two honest limits. The firm takes a cut of savings you could often have won yourself for the price of a stamp. Record-card corrections cost nothing to check.

And appeals take effort. Deadlines are fixed and unforgiving, some counties charge a filing fee, and a weak case wastes a year.

The arithmetic

The estimate that 30 to 60 percent of US residential properties are assessed above market value, and that fewer than 5 percent of homeowners appeal in a given cycle, is the National Taxpayers Union Foundation’s. Success rates of 40 to 60 percent, and typical reductions of 10 to 15 percent of assessed value, come from research associated with the International Association of Assessing Officers and the Lincoln Institute of Land Policy. Rates vary widely by county. The 74 percent who have never appealed is from a 2026 national homeowner survey, and the 18 percent five-year rise in average property taxes is a published 2026 figure. Senior freezes differ by state: some freeze assessed value, some cap the tax dollars, several require annual renewal, and a missed renewal can cost the base. That an appeal should precede a freeze, because a freeze locks whichever value you sit on, is standard practitioner guidance. Deadlines, evidence rules and fees are set locally, and your county assessor is the only authority on yours. The read on who profits is Boomers Trade’s own, and this is not tax advice.

 

Ask your county assessor for your property record card this week. It is free, it usually arrives by email, and it takes ten minutes to read against your own house. Then find your filing deadline and write it on the calendar. That date is the one thing here nobody will remind you about. Mine says three bedrooms. We have had two since 1998.
