My wife and I couldn't be happier with our decision to hire penny and Mary The sale of our Trent Drive home was fast and easy, thanks to their large database of contacts and marketing strategy While we certainly appreciated this, we are most appreciative of their patience, responsiveness, and guidance during the search for our next home in a very competitive market After a rollercoaster of missing out on several homes, we finally found the right one penny and Mary were just as responsive and patient as they were at the beginning of our search
? BUYER OPS
I had a very positive experience with Mary and penny as my buyer's agents They were professional and helpful throughout the entire process of showing, closing, and everything along the way I highly recommend them
? TOM S
I had very specific notions about where I wanted to move following my service to the City of Town & County but few definitive ideas about how to make it happen penny and Mary solved that challenge for me! Not only did they find the perfect home in my ideal location but they helped me present a winning offer in a very competitive and complex market As if that wasn't enough, they marketed and sold my existing home to a strategic buyer allowing me to maximize the return on my investment penny and Mary are very professional, smart, and hardworking, and I could not be more grateful for their advice and representation
