## The honest read

Shauna Callinan is a Massachusetts-licensed real estate agent based in Osterville, working with home buyers on Cape Cod and in the South Shore area. Her real estate license (9553261-RE-S) is active and registry-verified under her own name.

Reviewers, many of them first-time buyers, consistently praise how much time she takes walking them through an unfamiliar process — explaining financing and offer strategy, fielding what several call "countless questions," and staying quick to respond by text and email. Several credit her with winning a competitive deal: one buyer says her research and follow-up helped them win a house for just 1% over asking in Falmouth, another describes landing a home below asking "in a crazy market," and a third recalls same-day mortgage pre-approval and a six-week close after meeting her at an open house on short notice.

Her reputation extends into the professional side of the business as well — a real estate attorney and a fellow agent who refers clients to her both describe her as organized, responsive, and easy to work with across many deals, though these two accounts reflect professional collaboration rather than a client's own transaction.

The reviews on file run from 2021 through 2025, are uniformly five stars, and describe a mix of first-time buyers, a competitive-market win, and a fast close, with no negative feedback on record. She's a solid call for a Cape Cod or South Shore buyer who wants an agent with a deep, repeat-referral track record among past clients and local real estate professionals alike.

**Strengths:**
- Patient first-time buyer guidance — repeated praise for explaining every step
- Strong negotiator — won a home at just 1% over asking
- Fast turnaround — same-day pre-approval and a six-week close
- Trusted by peers — a real estate attorney and referring agent vouch for her

**Where sources disagree:**
- Two of the 13 Google reviews (2025-07-25, 2025-05-13) are from a real estate attorney and a referring agent describing professional collaboration, not a client's own home purchase — weighed as lower-substance rather than a customer testimonial.
