At Kinlin Grover Compass, we have extensive experience in pricing and marketing luxury oceanfront and bayfront properties. I take great pride in providing specialized services to both homeowners and home seekers of these distinctive waterfront residences.
Waterfront homes possess a unique beauty — one that is often best appreciated from the water itself. My exclusive marketing program is designed to highlight that perspective, attract qualified buyers, and create an elevated viewing experience.
Exclusive Waterfront Marketing Services Include:
-
Private transport by boat for property showings and viewings
-
Waterside marketing signage to capture the attention of boating enthusiasts and waterfront visitors
-
Professional photography and aerial imagery showcasing the property from and above the water
-
Strategic marketing and digital advertising targeted specifically to qualified luxury and waterfront buyers
-
Additional buyer services for properties featuring private docks or boating access
Whether you’re buying or selling a waterfront estate, a year-round residence, or assisting an aging loved one with a transition, I’m here to help you navigate every step with confidence, care, and expertise.

"Working with Pat was a breath of fresh air...the the experience of selling a home is stressful, but working with Pat was so easy and delightful. She demystified elements of the process, made others very easy, and stayed in consistent contact. Her advice was prescient and her demeanor always happy and supportive. We would work with Pat again in a heartbeat." -TS, Mashpee★★★★★
"We are pleased to highly recommend Pat Callahan for your real estate needs. Pat knowledgeably guided us through every step in the sales process. At one point we needed an electrician for an emergency repair. Pat came through in three hours!
We always knew we were in expert hands, and will not hesitate to use Pat for any of our future real estate matters!”
