Decide if an appeal is worth it
A quick checklist keeps the effort proportional to the potential savings.
- Is your assessed value above recent comparable sales?
- Do you know the appeal deadline for your county?
- Do you have clean evidence to support a lower value?
- Is the potential savings worth the time or fee?
- Can you explain the case in one page?
- What is the appeal window and evidence standard for my county?
- Would a professional appeal rep be worth the fee here?
- Does a successful appeal carry forward to next year?
