Key insight: Homeowners will pay $99-199 to avoid $500-2k in annual overpayment, but no one is packaging assessment appeals as a self-service product—it's a pure execution gap.

The Problem

Property owners overpay taxes annually because assessment errors go unchallenged—most don't know their home was mis-valued, and creating a competitive market analysis for appeals is expensive and time-consuming. Assessment offices make mistakes regularly, but homeowners lack affordable tools to audit and challenge them.

Target Audience

Homeowners in high-property-tax states (CA, TX, NY, IL) earning $75k-$250k annually, ages 35-65, who own appreciated homes but lack legal/accounting resources to appeal.

Why Now?

Property values spiked post-2020, creating assessment lags; many homeowners now face year-end appeal deadlines (Dec-Feb in most states) and rising property taxes are politically salient.

What's Missing

Existing tools focus on listing/buying, not assessment auditing; legal services are cost-prohibitive; public assessor websites are outdated and inaccessible.
