"Kathleen and Marina are true experts and professionals. We told them what we wanted and they delivered immediately. We took the first condo they showed us because it was perfect. They also helped us expedite all of the paperwork very quickly because we we're up against a very tight deadline. It all worked out perfectly because we worked with them!"

"I accepted a job in Florida and was on a 60 day timeframe to relocate. I didn't want to rent and truly wanted to find a home to live in. I had several obstacles preventing me from being 100% available to search for job requires me to work 12-13 hr. days, and my weekends were spent in TX packing up my current residence. In addition, I was new to Florida and wasn't sure what areas I wanted to live in, causing a lot of home searching. I was introduced to Marina from my realtor in Texas (Israel Flores). Marina accepted this challenge, and worked with all the obstacles to ensure that I found a home that would accommodate my needs. Marina was very professional, knowledgeable, and had my best interest at hand. She worked countless hours searching for places, doing a walk through with a video recording, when I was unable to get off work to view the home. She learned my style quickly and she sent me homes that she felt I would be interested in. She also setup last minute appointments"
