Marc Gup's Reviews & Ratings

Marc Gup

    • Honestly, I could literally write a book praising Marc's qualities and performance but ... simply stated, in our opinion, Marc is the very best agent you could find anywhere ... bar none. Even before our property was listed on Maine MLS, Marc carefully developed a marketing strategy that he felt would work best for our property and did it work!! After only one week, Marc presented FOUR offers to us all of which were well in excess of out asking price. Additionally, the highest bid was given to Marc within the first 24 hours of listing the property!! Lisa and I almost fell out of our chairs when Marc presented the highest offer which of course he saved until last! Marc's unique talent is unmatched and we are pleased to give Marc and his team the highest marks in all categories. Based on Marc's outstanding performance, we also chose Ryan Deveaux, a Marc Gup team member, to act as our Buyer Agent to help us in the selection and ultimate construction of our new townhouse at Dune Grass in Old Orchard Beach. Still a work in progress, Ryan continues to represent our best interests in this complex project. You need look no further for a Realtor. Marc Gup and his outstanding team can produce results you never thought were possible. He did this for us and he could do this for you. The very best!!

    • It is amazing to me to have signed an Exclusive Right To Sell on May 21, 2014 and to have closed on August 11, 2014 just $5,000 below the asking price for the above property. With your knowledge and professionalism and your staff you made a commitment to do all you could to sell this property in a very timely manner. And you did! Having been an owner of a large real estate company on Long Island, I knew immediately that I was in good hands. I appreciated your honestly and knowledge of the South Portland market and felt perfectly confident that you didn't promise anything you couldn't deliver. I just never expected it to be so quick. We signed the listing agreement in May but actually we didn't show the property until much later since there were tenants involved. Here again, you were respectful of my tenants and they responded positively. I don't live in Maine but my daughter and son-in-law are there and I have expressed to them to be sure to recommend you to whomever is planning-to buy or sell property in the Portland area. I can't thank you enough for the fantastic job you did for me.

    • If you want a team to come into your home and tell you like it to straighten up your home to sell it, information on the market and sales in your neighborhood, and to be with you every step of the need Marc and his team. They are honest, ethical, and up front with their clients. These are true professionals who know how to sell your home---and help you purchase one, too---; husband and I would deal with no one else.

    • We've now purchased two buildings and sold one with the help of the Marc Gup team and I wouldn't want to work with anyone else! They are always so helpful, professional, knowledgeable, and honest. I have no idea how they do it, but I always feel like I'm getting the best end of the deal, but I also know the other parties in the transaction feel the same way too. To make not only your clients but other realtor's clients feel like they are being respected and given honest information about such a big decision while also making both parties feel like they got a deal is an incredible art. Marc has perfected this art. I have never met a harder working team.

    • I can't say enough about Marc's professionalism, competence, and service. From the outset, he laid out a selling plan based on his years of experience, and this approach proved to be exactly what worked for our market and clientele. Time and again, he came through when I and my sisters (selling our parents' home) were overwhelmed; he managed multiple contractors, serving as the connection point and coordinator who kept everything on track. He set the price point perfectly, where we feel we got the best offer we could have, and the new owners are also delighted. Marc is an extraordinarily hard worker, and his success speaks to his stellar combination of quality and effort. I highly recommend him and his team!

    • I first met Marc while trying to sell my house 'By Owner.' Marc walked in, took a look around, and told me that he thought it was a fantastic house and that it would sell. "That being said," He told me, "If you decide you'd like some help, please let me know." I put his card on the top of my pile and thanked him, hoping to not have to take him up on his offer. When my 'For Sale By Owner' deal fell through a couple of weeks later, Marc was the first person I called. Selling a home had turned out to be more difficult than it looks, and I just didn't have the time or energy required. Almost none of the other realtors I had met had offered the same laid-back yet informed demeanor, and none of them had conversed as sincerely with me. For those reasons and more, I had kept Marc's card at the top of my pile. I am glad I did. Marc and his team took full control of the process almost immediately, and in so doing, took a lot of the weight off my shoulders. While being able to take a step back was nice, I didn't feel in the dark. Marc kept me completely in the loop, calling and emailing me frequently about any updates or questions that arose without pestering. He always took the time to answer all of my questions, and he offered solid advice when I needed it. With Marc's help we put the house under contract almost immediately, and everything went off without a hitch. Instead of completely moving on to other deals after we had signed, Marc and his team kept on top of things. I was always kept up to date, and I never worried about missing a deadline with helpful reminders from his team. Marc stayed with us through the entire process, and even came to the closing with a card and gift certificate to me and my girlfriend's favorite restaurant. Overall, Marc is a very solid, reliable, and hard working Real Estate Professional. His attention to detail, approach, and knowledge are top-notch. I have already recommended him to friends and family, and I will continue to do so. If you are also looking to sell your home, you can't go wrong by giving Marc a call.

    • Marc and his team are very professional but also very approachable, and Marc certainly knows the real estate market. We were keen to sell, and listed our condo on Sept 7th and closed on Oct 25th. Highly recommended!

    • Marc is a top-notch and thorough real estate professional and trusted advisor. Marc took the time to provide a thorough market analysis, explain the transaction every step of the way, and facilitate the sale of my home. Marc was extremely responsive to any questions I had by text, email or phone. Marc's staff is highly knowledgeable and know exactly how to facilitate a real estate transaction. They thought of everything and were a pleasure to work with. I highly recommend Marc Gup and the Marc Gup team
