Derek was a pleasure to work with. He helped us prep for the sale of the house almost 2 years before. When the time came to sell the house, Derek's guidance helped us stage and and sell the house in under a week! We received multiple offers and Derek helped facilitate a deal that was optimal for the us and the buyers.
