## The honest read

Leverage Real Estate is a small Quincy brokerage built around John Gambone, who reviewers describe as heavily hands-on — coordinating attorneys, lenders, inspections and even smoke-detector compliance rather than just showing properties. His Massachusetts real estate broker license is verified active.

The written record, 17 reviews since 2022, leans heavily toward buyers and sellers who say Gambone explained the process clearly and stayed available throughout. One 2026 buyer credited him with "smart and spot-on" pricing and negotiation advice plus a referral to a lawyer and mortgage contact that made closing smooth; a 2024 seller with an out-of-state, hands-off sale said he handled everything from listing photos to smoke detectors. A handful of reviews also name other agents at the firm — Amanda James and Christie Rioux — with similar praise for responsiveness.

One July 2026 review breaks sharply from that pattern: a client called Gambone's advice "surface level" and said he had no real grasp of the market when it came to guidance for the present and future, warning others away. It directly contradicts the market-knowledge praise that runs through the rest of the record, and it's recent enough to be worth asking current clients about before signing on.

Confirm which agent at the firm you'd actually be working with, since reviews describe more than one person handling deals under the Leverage name.

**Strengths:**
- Full-service handling — coordinates attorneys, lenders and paperwork
- Clear communication — reviewers cite steady availability and explanations

**Concerns:**
- Advising dispute — a 2026 review called his guidance surface-level

**Where sources disagree:**
- A 2026 review disputing John's market knowledge and advising skill directly contradicts the knowledge-focused praise in most other reviews
