Client experience

"I've known Tim & Ed for over a decade now and I chose them to sell my mother's home because I knew they would treat the sale as if it were their own. This was not my first time doing business with them and for my second experience, it exceeded all of my expectations. This sale was emotional because the home being sold was the one I grew up in. It was also my mother's nest egg so everything was riding on this sale. The services from the Massey Allen group were first class. It ranged from lending options to upgrade to professional advice regarding numerous strategies. During the whole process, I felt like it was a family member looking after this sale with our best interest in mind. Absolutely I would recommend the Massey Allen group for anyone. There is no shortage of agents out there, but character, class and integrity are what makes them stand out. For your one stop shop & individualized experience, look no further."

"When we decided it was time to sell our condo, we knew The Massey Allen Group would be the perfect agents to help us through the process. Ed and Tim immediately set up an appointment to meet with us, view our property, made some minor suggestions for improvements to help our value, and began the process of getting our condo on the market. They stayed in touch through the entire process and kept checking in to make sure we didn't have any questions and were doing okay with the selling process. We appreciated this because this was our first time selling a property and had no clue what to expect. With Ed, Tim, and their team's help, we were able to accept a fantastic offer and close escrow in a very timely manner. If you are looking for honest, trustworthy, and reliable agents, look no further than the Massey Allen group"
