"Marina took some great photos and videos for us which enabled us to buy our property unseen and both Marina and Kathleen were always available to help and answer any questions. "

"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 !"
