I had the pleasure of working with Chase, and MaryAnn Walker on a recent purchase where I was helping our buyers with their financing. Unfortunately, as we were approaching closing our purchase we discovered we had run into an unscrupulous builder/developer, who was not going to honor our contract and close the transaction. That's when Chase got involved. Although our clients my have won a suit over the seller's breach of contract, the grief to dollar ratio was not in their favor. MaryAnn quickly found them a replacement property that had come on the market and was an even better fit. Chase and MaryAnn's professionalism and client focus, navigating one of the most ridiculous scenarios I've seen in 20+ years in financing real estate, was tremendous.

I have been working with Chase Costello for over a decade. It’s great to see the success he is having with his clients and his team. Chase is the best at what he does. He’s an excellent negotiator and he always fights for his clients to get the best deal possible. It is easy to refer Chase to friends and family when they’re interested in purchasing or selling a home.

He got us top dollar for selling our house! Chase came to us in a very professional manner and let us know what we had to do to sell our house for the best price. He gave us a timeline to be moved out based on the market and upcoming holidays and recommended some work that could help it sell. His team accomplished getting our house on the market the weekend before 4th of July and we reviewed offers better than we expected the following week. There were no bad surprises but plenty of great ones!
