What our clients say
"Billy was diligent, patient, and thorough when it came to the purchase of my new home. I’m a first time buyer and thought I would be overwhelmed by the process, but from the start Billy made it clear he would walk me through step by step. Billy is not your standard Broker, but one that values the buyer/seller/broker relationship with integrity."
Billy helped me with remodeling a vacant apartment and leasing it out. He was responsive and resourceful. Billy had helpful and creative suggestions to improve the project with reasonable cost. He smoothly handled all obstacles and complications. The finished unit was successfully leased out for a good price. I would highly recommend Billy DeMartini for all of your real estate needs!
