How the free assessment check works
The free check finds your home in the county's assessment records and shows how its assessment compares with similar homes nearby, or with local sale prices or your area's house price index where that is how a county is checked. You see the numbers whatever they are, with the homes used. It takes about 2 minutes, needs no signup and sends nothing to the county. If you decide to appeal, you file it yourself.
