The Cosgrove Aiken Team works out of William Raveis' Osterville office, handling both home purchases and sales. A couple of things repeat across their Google reviews: clients who came back for a second or third transaction, and at least one same-day turnaround — a 2022 review describes a client selling one home and buying another in a single day. The transactions reviewers describe most are ordinary home purchases and sales — offers, comparable-pricing research, and closings. In a 2022 review, one buyer credited Joe with explaining the process in plain terms and Kelly with researching what similar properties had sold for nearby, then says the team handled everything from the offer through the closing. Reviewers also describe Joe and Kelly as responsive, saying they're easy to reach with questions along the way. There isn't much to flag here — the six reviews on file are all positive and don't touch on commission rates or fees, so that's worth asking about directly before signing on. This reads like a team suited to buyers or sellers who want a familiar point of contact from the first showing through closing — several reviewers returned for more than one transaction with them.
We had a fantastic experience with Joe and Kelly! They were knowledgeable, prepared, responsive, and willing to work on all the small tasks behind the scenes. Great team!
Kelly and Joe are truly amazing to work with. They make a complicated process simple and are always available to answer questions or offer advice. I look forward to having the opportunity to work with them in the future.
Joe & Kelly - We can't thank you both enough for all your help during the process of purchasing our new home. You brought us to ease the very first time we look at the one. Joe was able to explain things to us in a way that made sense. Kelly did an awesome job checking out what other properties went for in the area. You handled everything professionally from submitting the offer right through the closing. Thanks for making this as enjoyable and stress free as buying a home can be. The team works, so give them a chance. You will not be disappointed. Thank you again from the bottom of our hearts" Annette & Howard (Mashpee, MA)
Had a great experience working with the Cosgrove Aiken team! They made it possible for me to sell my home and purchase another all in the same day!
