Questions
Is asking for a reassessment allowed in California?
Yes. Under Proposition 8 (Revenue and Taxation Code Section 51), the county Assessor must enroll the lower of your Prop 13 base year value or your property's market value on January 1. Most counties accept informal review requests.
What if my property isn't overassessed?
We tell you, and there's nothing to buy. Reports are only offered when your 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 phone number and website.
What's the difference between an informal review and a formal appeal?
An informal review generally has no statewide deadline, no fee and no hearing; you contact your Assessor directly. A formal appeal is filed with the Assessment Appeals Board between July 2 and September 15 or November 30, depending on the county, and includes a hearing.
Do you file anything for me?
No. We're a data research service, not a law firm or tax agent. You decide what to do with the report, and no reduction is guaranteed.
