John DeLellis works Cape Cod real estate out of a Centerville office, representing buyers and sellers across Barnstable's villages and the towns around it — his own site names Osterville, Cotuit, Mashpee, Sandwich, Falmouth, Chatham and more as his working territory. A June 2026 review captures the kind of outcome that keeps showing up in his account: a home that sold in the first 45 minutes of an open house, $25,000 over asking price. Further back, a 2025 review describes him managing every required inspection for a buyer who couldn't be on-Cape to handle it herself, closing the purchase remotely start to finish. Across seventeen five-star Google reviews running from 2023 into 2026, the two things clients name most are speed of response and showing up prepared. His Massachusetts real estate license, number 9577833, is active and checks out directly against the state registry — the same number his own site publishes, so there's no discrepancy to flag. He also lists OSHA, Hazmat and Heartsaver credentials and an International Facilities Management Association membership, carried over from a prior twenty-year career in facilities management rather than anything real-estate-specific. Worth noting before taking the five-star run at face value: a review posted in December 2025 is signed by another real estate agent describing a co-broking transaction rather than a client describing a purchase or sale, sitting in the same block as the client testimonials. There's no BBB listing and nothing negative from any client so far — which also means there isn't a documented tough case to judge how he handles one. He's a reasonable call for buyers and sellers anywhere from Falmouth to Chatham, especially anyone managing a purchase from off-Cape, and it's worth asking directly about his current pipeline given how much of this account comes from repeat closings rather than one long public history.
Our home sold in the first 45 minutes of an open house — $25,000 above asking price — and we have John DeLellis to thank for it. From the start, John's expertise in pricing strategy, property marketing, and pre-sale decision-making set us up for success. But what truly sets him apart is his deep investment in his clients. He doesn't just do the job — he shows up for it. (Literally. He arrived at our walk-through with his leaf blower in hand because we couldn't be there ahead of time to get the house ready.) His integrity, honesty, and genuine commitment to the people he works with are unmatched — and beyond all of that, he's simply a great person we're proud to call a friend. If you're looking for someone with deep roots on Cape Cod — who understands local laws, local landscapes, and local culture — you've found your guy. We wholeheartedly recommend John without hesitation.
John is an amazing realtor.. I have seen the way he treats his buyers and sellers first hand.. His clients are always pleased with his service. He is well known in the community… If you are considering buying or selling you should give him a call
John DeLellis was professional, responsive, and made the entire process easy from start to finish. Highly recommend working with him! Awesome realtor!
I can’t say enough good things about John DeLellis. He is truly a stand-up professional and someone I hold in the highest regard as a fellow real estate agent. John is not only knowledgeable, caring, and kind with his clients, but he brings that same level of professionalism and generosity to his colleagues as well. When I listed a home in a neighborhood where he does a significant amount of business, John was incredibly forthcoming with insights, local context, and helpful details. He was open, collaborative, and genuinely invested in helping the transaction go smoothly — a quality that speaks volumes about his character. In an industry where cooperation matters, John sets the standard. I would trust him with one of my own clients any day of the week, without hesitation. Anyone fortunate enough to work with him — client or colleague — is in excellent hands.
John was a pleasure to work with. He came prepared to our initial meeting and gave sound practical advice. He carefully listed the property, held one open house and we were in contract in 8 days at a price above listing. He handled all the necessary inspections since we were not local which allowed us to close the transaction seamlessly. Very professional!
