Questions
What is a decline in value?
Under Proposition 8 (Revenue and Taxation Code Section 51), the county Assessor enrolls the lower of a property's Prop 13 base year value or its market value on January 1. When market value is lower, that's called a decline in value.
What if my property isn't overassessed?
We show you that, and there's nothing to buy. The report is only offered when the assessed value is meaningfully above our market estimate.
What's in the $49 report?
A two-page PDF with your property details, 4 to 6 comparable sales, an estimated market value range, neighborhood Census data, and your county Assessor’s public contact details. It’s informational research: no forms, letters, recommendations or savings estimates.
What's the difference between an informal review and a formal appeal?
Informal reviews are run by county Assessors and generally have no statewide deadline, fee or hearing. Formal appeals go to the county Assessment Appeals Board, are filed between July 2 and September 15 or November 30 depending on the county, and include a hearing.
Do you file anything for me?
No. We're a data research service, not a law firm or tax agent. We don't file or submit anything, contact the county for you, or offer one-on-one review after purchase.
