"Diane is a true vale added broker. I have moved 4 times in my adult life and the experience with Diane was a pleasure. She saw my home and gave me invaluable tips on how present it at its best. She is basically a stager, decorator, and realtor in one. Diane found me my dream home for the next phase of my life. She helped me construct a proper bid that I felt good about. I love my new house. Following Diane's guidance saved a lot of time and money. Diane understands the entire process and guides you every step of the way. She is also responsive, detail oriented and someone you want on your team. Diane is worth her weight in gold."

"Diane Cookson's, knowledge, skill and experience came together to sell our home quickly amid the uncertainty and restrictions imposed by the Covid-19 pandemic. It started with detailed metrics in regard to data about recent sales of comparable homes and other details regarding homes in our general price range that were on the market. Diane has an honest straight forward approach. After pricing we moved to the photographs, staging and implementation of her marketing plan. The photography and positive changes brought about by the staging were stunning and brought results. We priced the home based upon her recommendations and she delivered on her promise of multiple offers within 30 days. We closed on a schedule that met our expectations and we highly recommend Diane because of her highly professional skills, integrity and most importantly her results."

ā˜…ā˜…ā˜…ā˜…ā˜…
"If you want someone experienced in all aspect of selling or purchasing a house, Diane is your person. We have worked with brokers and never have we come across someone so honest, hardworking, friendly and bright as Diane. She is the most helpful, caring, reliable and efficient broker by far. She will not waste your time trying to sell you something, she has you and your family's best interest at hand. Diane is extremely knowledgeable with the ins and outs of a home, septic and pool inspection. She gives you guidance when you don't know. She is Diamond plus!"

ā˜…ā˜…ā˜…ā˜…ā˜…
"Diane was referred to us because of her significant local knowledge, reputation for outworking her competition and her marketing strategies. She helped us get our house ready to sell quickly, took amazing photos and videos and created significant interest in just a few days. The result: We received multiple offers and sold our home in less than two weeks! Diane won't just tell a seller what they want to hear either. She provides candid and fair feedback that is not often done by realtors. She is responsive, well networked and detailed. We can't thank her enough for her hard work. We'd recommend her to anyone selling a home in Bergen County."

ā˜…ā˜…ā˜…ā˜…ā˜…
"Diane Cookson is an absolute gem. THE BEST. I base this claim on very recent personal experience. My wife and I worked with Diane for the better part of the past 3 months in search of our first house, having never met her prior to working with her. She was the ideal partner for such a venture. Diane understood almost immediately after meeting us what we were looking for in a house and from that point on made us feel like she had no greater professional priority than to help us find it. As a professional, she is available, she is responsive, she is tireless and extremely accommodating. She listens, she's beyond patient and she communicates well. She's smart, she's savvy, she's experienced and well-connected. While she wasn't afraid to express her opinion, Diane never nudged us in one direction or another; understand that we looked at countless houses in a pretty wide price range. She simply wanted us to be happy wherever we landed. For all of Diane's wonderful qualities, it's no surprise she is as well-respected and so highly thought of in the community. I could not imagine being in better hands as a first, second or tenth time buyer!"
