"I am a resident of New Jersey and inherited a lovely condominium in Lighthouse Point, FL... since I was dealing from afar it was important to me that someone who was responsive and attentive handle this sale for me. Kathleen Costanzo listed and sold the property within approximately a month's time. Knowing that I was a distance away in New Jersey, Kathleen offered to help me in any way she could. Her effort was above-and-beyond what I would have expected from a realtor. I am glad I selected Kathleen to represent me as as she constantly kept me informed and guided me every step of the way... things went smoothly, the sale was quick, and I received a very fair price for the property .... three cheers for Kathleen !"
