Mark Sweeney is professional and very knowledgeable of the housing market.

Mark Sweeney made selling my mother’s home seamless. His knowledge of the market was so helpful with setting a realistic sales price for her home. He gave excellent advice on prepping the home for sale. Mark kept us informed every step of the way from the initial listing, scheduled visits, the open house and receiving bids to finally going into settlement. Mark was always available.
