Testimonials

"We have purchased 1 house and sold 2 houses with Justin Flanagan. The office is knowledgeable, hard-working, and responsive. They will help you find the house you want. and work really hard to get a buyer. They always follow up with the showing brokers for feedback and make sure you, the seller, receive and understand the feedback. They move properties when others cannot. I think that is due to their hard-working, enthusiastic team."

"Topmark Realty was a lifesaver for me and my family. We found Topmark online along with a couple of other Realtors, but Topmark fit our needs better and gave us confidence that they could get the job done, and they did. It was a very stressful time for my family and me, but with Topmark's help, we were able to get the house sold in less than three months. They marketed our house and staged an open house for one weekend and were able to get us a buyer. Topmark worked with us and helped us out in so many ways. There was doubt at times, but they did their best to make sure everything was handled properly and in order. They really do care about the families they are helping. If you are on the fence about going with Topmark, don't be. They will do their very best to get your house sold in a timely manner. Considering we had a deadline, they were able to sell and close the house before then. I would definitely recommend Topmark to help you sell your house. The entire team put in a tremendous amount of effort and time"

"We are very lucky to have Mr.Justin S Flanagan as our Realtor. He is very professional, his explanations and advice all the time always valuable for making our decision. He is smoothly communicating with the other Agent in a friendly way, which has saved us a lot of tenses. The best thing I liked was that he has ethics, works for us, and respects the other side also."

"We felt very lucky to have Justin Flanagan as our realtor. He went over and beyond the "call of duty" to accommodate us. He was tireless in helping us and was positive and knowledgeable. He pointed out potential problems, and was very honest with what he saw, and wasn't out for a "quick sale". We very much appreciated all his efforts and would wholeheartedly recommend him to anyone!"
