We build a filing-ready appeal evidence packet — the comparable sales, the analysis, and your county's exact filing instructions — so you can appeal your assessment yourself.
$49 flat fee · one-time · no ongoing obligation
One question before you pay: which deadline is your county under? California closes appeals on two dates, and we're past the point where we can build a packet and leave you time to file in the earlier group.
Not sure? Your assessment notice or your county's Clerk of the Board page states it. Pick Sept 15 if you're unsure — we'd rather email you than take $49 you can't use.
Hand-reviewed by a real person, delivered within 24 hours of your completed intake form · California homes only — single-family, condo, or townhome · Full refund if the evidence doesn't support a case · Informational only, not legal or tax advice
Pay the $49 flat fee and tell us your property address and APN. We pull your assessment record and last purchase details.
We research comparable sales inside the legal evidence window, vet each one, and derive a defensible proposed value — the same method we used on a real Alameda appeal.
Within 24 hours of completing your intake form you receive a PDF packet plus step-by-step filing instructions for your county. You file it yourself before your county's deadline.
Your county's filing fee (typically $0–$100, paid to the county) is separate from our $49 packet fee.
We cover residential property only — single-family homes, condos, and townhomes. Not commercial, industrial, agricultural, vacant land, or apartment buildings (5+ units).
$49, one time. We don't take a cut of your savings and there's nothing to cancel. You stay in control and file the appeal yourself.
If we don't find you a case, you don't pay. We research your property first. If the comparable sales don't support a reduction worth roughly $400 a year or more in tax — or if we can't build a defensible packet for your property at all — we tell you what we found and refund the full $49. You keep the honest answer either way.
This is a refund promise about our research, not a promise about your appeal. Once we deliver a packet, the outcome is decided by your county's assessor or appeals board, and no one can guarantee that.
Why we started this. We built this after researching our own Alameda County appeal — a Dublin home assessed at $1,804,040 where comparable sales supported roughly $1,525,000, a difference worth about $3,200 a year in tax. The research method worked, so we're offering to run it for homeowners across California.
That was our own property and our own result. It is not a promise of any particular outcome for your home — every property and every set of comparable sales is different.
No one can promise that. We research your property first, and if the comparable sales don't support a case worth filing we tell you honestly and refund the $49 rather than sell you a packet. Prop 8 "decline in value" reductions are also temporary and reviewed annually; they don't change your Prop 13 base year value.
Then we refund you. We do the comparable-sales research before we decide there's a packet worth building. If the evidence doesn't support a reduction worth roughly $400 a year or more in tax, we email you what we found and refund the full $49 — typically within a few business days of the refund landing on your card. We'd rather give the $49 back than sell you a packet that costs you more to file than it saves.
Not in this $49 service. We build the evidence packet and give you exact instructions; you file it with your county yourself. That's why it's a flat fee with no cut of your savings.
Your property address and APN, and ideally your latest assessment notice and your purchase price/date. We handle the rest.
No — keep paying your tax bill on time. Appeals don't defer payment; if you win, you're refunded the difference.
It depends on your county. Counties that mail value notices to every owner — including Alameda, Santa Clara, and San Francisco — close September 15, 2026; most other California counties close November 30, 2026. Your packet states your county's exact deadline. Because we hand-build every packet and you still need time to file, order well before your deadline.
All of California — the appeal framework (Prop 8 decline-in-value, the Jan 1 valuation date, the comparable-sales evidence rules) is identical in all 58 counties. Alameda County is where we started and know deepest. We don't cover other states yet: their deadlines, valuation dates, and assessment rules differ.
Residential only: single-family homes, condominiums, and townhomes in California. We don't take commercial, industrial, or agricultural property, vacant land, apartment buildings of five or more units, or mobile homes on leased land — those are valued by different methods (income and cost approaches) that our comparable-sales research doesn't address. If you order one of these by mistake, we refund you in full rather than build a packet we don't stand behind.
We'll email you once before your county's deadline so you don't miss the window — California counties close on either September 15 or November 30, so we need your property's ZIP code to send you the right date. One email. No spam, no sharing your address.
Thanks — you're on the list. We'll email you once before your county's deadline.
