About Matthew
A Local Perspective on Lakes Region Real Estate
Matthew Costantino grew up on Ossipee Lake and has spent his career thus far building a reputation as a dedicated, knowledgeable agent in one of New Hampshire’s most sought-after markets. He works across the full breadth of the Lakes Region, from the shores of Lake Winnipesaukee to the quieter towns along the Maine border.
Costantino Real Estate LLC was founded in Ossipee in 2009 by Matthew’s father, Gerard Costantino, and has grown into one of the most recognized independent brokerages in Carroll County. Growing up and working alongside his father inspired Matthew to bring the same level of honesty and dedication to the table that made Gerard well known throughout the region.
“The Lakes Region is a place people fall in love with for a reason. I am honored to be able to help clients find their place in it every day.”
His approach is straightforward. He listens carefully, gives honest assessments, and stays focused on what actually matters to his clients. Whether someone is buying their first place to call home or selling a home they have owned for decades, Matthew brings the same care and attention to every transaction.

Full Service
From the first conversation through closing day, Matthew handles every detail with care. You will always know where things stand and what comes next.
