We are so happy...

We are so happy that we chose Joanna for the sale of our house and that she accepted and lead us throughout the process. Her ideas, pacing and implementation were incredible. We were so happy with the house photos and the video was precious! Her pricing strategy was right on! We greatly appreciated Joanna's sense of humor and positivity throughout the entire process!

Joanna is an excellent sales broker - strategic and kind, and at the top of her game!

Joanna is an excellent sales broker - strategic and kind, and at the top of her game! Her full service representation makes the process of selling your home seamless from the first conversations about pricing strategy and sales timing, through to staging, last minute fixes, and finally to a successful sale. I would highly recommend Joanna.

Beyond 5 Stars! I closed the sale of my Park Slope coop

Beyond 5 Stars! I closed the sale of my Park Slope coop at above asking price today! Just like you, I had googled tons of reviews to best select an agent. As a first-time seller, I was very apprehensive about this whole unknown process before me. I met a few brokers but Joanna stood out as she saw the value of my pre-war apartment unlike the rest who advised renovations. Professional, knowledgeable, extremely down to earth, and as one of the most genuine individuals I’ve ever known, Joanna held my hands patiently from day 1. She staged my apartment artfully, advised a just right listing price, and was always positive, in communication, and readily available for any questions and concerns. I felt extremely supported by Joanna and trusted her to work her magic. And magic she accomplished; we had gotten multiple offers! Selling from out of state, I was worried about the potential time and energy required in the process but other than cleaning up prior to staging, I feel like I hardly lifted a finger! I am so glad I chose Joanna to be my agent and I will work with her again in a heart-beat.

Having worked with Joanna Mayfield Marks for the past 10 years

Having worked with Joanna Mayfield Marks for the past 10 years on both finding and selling a condo, I can’t recommend her services enough. She is knowledgeable, enthusiastic, honest and dedicated. Joanna and her husband Josh are an incredible team with hearts of gold. If you are searching for the best real estate agent in Brooklyn, you’ve come to the right place!

Joanna Mayfield Marks has been an amazing person in this

Joanna Mayfield Marks has been an amazing person in this very complex mosaic of selling our co-op apt. shares in Bklyn, NY She has gone over and above anything I ever experienced or expected. Joanna helped clean out our yard, she staged the apt. so it looked so beautiful! Joanna's advice, her wisdom, her strength and her compassion all came together in our dealings with her. I consider Joanna an angel in many ways. She brought us peace of mind in all the complexities that come with selling the shares of our apt. And her generosity of spirit has inspired us going forward..

Joanna helped me sell my coop apartment in Sunset Park

Joanna helped me sell my coop apartment in Sunset Park. She was extremely hard-working and generous—she and he husband helped with numerous small fix-ups and also moved things to stage the apartment for showing. She knows the quirks of Sunset Park coops well, which was helpful. This was the first time I was selling a home and I'm so glad I had her to help guide me through the process. She's an all-around great person and was a pleasure to work with.
