The clearest difference is geography — Overassessed is built for California, Grove Hopper works nationwide. We're Grove Hopper, so we're not a neutral party — but every claim about Overassessed below comes directly from overassessed.co, checked the same day this page went live.

|---|---|---|
| Price | $50 flat, one time | $45 flat, one time, for their "Filing Guide" |
| If your appeal is denied | The free report told you your odds before you paid — no refund mechanism needed | States a money-back offer: "Get a reduction or get your $45 back" if you send the county's denial letter |
| What you get | County-specific forms (pre-filled where the county allows it), comparable-sales evidence, a step-by-step filing walkthrough | Comparable sales ranked by strength, dollar-for-dollar adjustments, a ready-to-submit value narrative, hearing talking points, and a downloadable PDF evidence packet |
| Who files it | You — we prepare the documents, you review, sign and submit them yourself | You — self-file ("submit your request through the Assessor's office") |
| Cut of your savings | None — flat fee only | None stated — "no percentage of savings, no recurring fees" |
