"Typical cut" is the median drop among values that came down. Informal review with the assessor comes first; owners who aren't satisfied go on to a hearing before the Board of Equalization and Review, so the same home can appear at both levels.
What kind of appeal works
Where Orange County's records say why the owner appealed, the difference is stark:
The county's record was wrong
Wrong square footage, bedrooms, condition and similar. 599 of 689 appeals lowered the value.
"It's worth less than that"
A market-value argument alone. 218 of 432 lowered the value.
What this means if you're thinking of appealing
- Check the record firstA wrong square footage or bedroom count is the easiest kind of appeal to win, and the assessor can fix a factual error in any year.
- Start with the informal reviewIt's quicker than a formal hearing, and if you're not satisfied you can still take it to the Board afterward.
- Bring sales, not feelingsRecent sales of similar homes near yours are the evidence the board weighs. A higher tax bill alone isn't a reason it can act on.
- Know it can go up3% of decisions here raised the value. Past results don't predict yours.
