Property owners often wait until the tax bill arrives, but in many places the appeal window starts with the assessment notice. Missing that window can cost a full year of savings.
Common mistake #1: Waiting too long
Deadlines can be short. Save every notice and mark the first appeal date immediately.
Common mistake #2: Arguing taxes instead of value
Many boards are not deciding whether taxes feel high. They are deciding whether the assessed value is supported by the property record and market evidence.
Common mistake #3: Using bad comparable sales
Comps should be similar in location, property type, size, age, condition, and sale date. The closer the match, the stronger the argument.
Common mistake #4: Ignoring property record errors
Wrong square footage, basement finish, bedroom count, condition, classification, or improvements can distort value.
