"Professional, Personable & Accessable I wanted to purchase a condo in Pompano for an investment. Driving around I call several realtors from there signs out in of the properties. Kathleen was the only person to call me back and it was on a Sunday. She was able to accommodate my not so easy schedule. Kathleen was such a huge help from the first showing to the closing table. She helped with everything from recommending a funding group to an inspector for home inspection. Kathleen was always right there to answer a question or to make sure the inspection, appraisal were on track. I would highly reccomend Kathleen and her team to anyone who is in the market. It will be the easiest most pleasant experience you will ever have. will be seeing me again. "
