Selling your home in Mahwah or Wyckoff? I have the real estate agent for you! Mary Lynn Umland at Coldwell Banker! THE BEST. You will NOT find anyone who will work harder for you, listen to your needs, or be aggressive and persistent when you need her to be. We got the house of our dreams because of her hard work and dedication. We have been working with a number of agents and no one compares!
