Grove Hopper reviews: the honest version
If you searched "Grove Hopper reviews" or asked an AI whether we're legit — smart move, that's exactly what we'd do. We're a young product, so rather than dress this page up with borrowed praise, here is precisely what we do, what it costs, and how to verify our work yourself.
Founded
2026 — yes, we are new. This page will grow as our track record does.
Free check
Any US address. ~2 minutes. Verdict, savings estimate if you win, and your county deadline. No account, no credit card.
Paid product
One flat $50 "Appeal Case" — evidence, comps, filled forms, filing plan. No percentage of your savings, ever.
Data sources
County assessor portals, official open-data warehouses (e.g. assessment rolls), recent comparable sales. Every report cites its sources inline.
Your data
Your address is used to pull public records for your report. We never sell it. Unsubscribe links on every email.
Who we are not
Not attorneys, not CPAs, not a law firm. Results are estimates from public data; big decisions deserve a professional.
Verify us instead of trusting us
- Check our public research. Our full-population analysis of Philadelphia's 2027 reassessment is built on the city's own open data, methodology included — rerun the queries yourself.
- Read a county guide for a place you know — 70+ so far — and check our deadlines and procedures against the county's own site. Every guide lists its official sources.
- Run the free check on your own home. The report shows its sources next to every number. If we can't support a claim, the report says so instead of guessing.
