Verified record
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.
Shauna was an incredible guide throughout the entire home-buying process, making everything feel smooth and stress-free. She helped us find our forever home and made sure every detail with the offer was handled with care. Beyond the purchase, she warmly welcomed us to the community, making us feel truly at home.
Shauna was absolutely amazing to work with! As first-time home buyers, we had a lot of questions and didn’t always know what to expect, but she guided us through every step of the process with patience, clear communication, and genuine care. She took the time to explain everything in detail, made sure we understood our options, and was always quick to respond when we needed her. Thanks to her expertise and support, we felt confident and informed from start to finish. We’re so grateful for all her help and would highly recommend her to anyone looking to buy or sell a home!
As a real estate attorney, I’ve seen firsthand how well Shauna handles her deals—organized, responsive, and always looking out for her clients. Even better, she’s just a genuinely kind and easy person to work with. Highly recommend her to anyone buying or selling in the Cape Cod and South Shore areas!
Shauna is one of my absolute favorite people to work with. We’ve done so many deals together over the years, and every single time, she shows up with professionalism, clear communication, and such a calm, grounded energy. Her clients love her, and it’s easy to see why. She truly cares, she knows her stuff, and she’s just someone you want on your side. I’m also incredibly grateful for the referrals she’s sent my way — it means so much to be trusted like that. Can’t recommend her enough!
