Where can I get started. The recommendation we initially got for Laren fell through by accident. And for some reason we kept pushing to work with Karen. I'm so glad we did. Karen had the experience to walk us through a stressful process of collecting all the information we needed to make the process much easier. We're so happy we were able to land in someone's hands with so much patience and knowledge . Being first time home buyers my wife and I, we definitely needed someone like her. We just want to say thank you. We will definitely keep Karen in mind for family and friends. And you never know. Even for my wife and I in the near future.

There is really a lot to say about our agent Karen. We really dropped the "Agent" title real quick and thought of her as a friend. We had lots of discussions about the large verity of homes along with the different areas to look for what we needed. Along the way we laughed at the struggles of finding the perfect home for our family. We developed such a great relationship. We felt very comfortable calling her whenever something came up that we were interested in. We had heard horror stories about other agents. Nothing of that nature with Karen. We couldn't have had a better FRIEND "Agent" for our first time buyers experience. Thank you for the wonderful excitement we had Karen. Looking forward to having the same experience with you once again in the future.

Karen Castillo was great, we loved working with her. She had a lot of knowledge of the areas we were looking, insights on the market, strategies, etc., but really the things that made us love working with her were that she was very kind and caring, flexible with us as first time homebuyers in a difficult market, and really always was there for us when we needed her. Overall we had great experience working with her.

Karen Castillo is your above average and top performing agents that you want on your side. She is very communicative, patient, knowledgeable, and easy to work with. There are three things that made her stand out and why I recommend her. First, her confidence in her answers and decisions is reassuring when we had doubts or concerns anytime throughout the process. Secondly, she isn't just there to answer your questions and get the job done, but goes above and beyond by asking you very important questions that you might not think of. This is especially very important when you are a first time home buyer and are not familiar with the process. Thirdly, she grows onto you as you start looking at homes - specifically getting to learn what types of homes or styles you like, and what you don't like. She can basically read your mind and get an idea of what you're thinking based on first glance of a home.

Karen was fantastic. An absolute pro. She put all of my concerns to rest. Gave me great advice. And came through for me big time. I would definitely work with her anytime I have a property in the Los Angeles area. ⭐️⭐️⭐️⭐️⭐️

Text book execution. Thumbs up. Across the board

Diana
Torrance, CA - Nov 22, 2020

Karen's personality is top notch. It was easy to work with her and she answered any questions I had. She made me feel comfortable through the process.

Even though it was my first home purchase, Karen made it seem easy. She was always on top of things and did everything quickly and always got back to me with answers to any questions I had. She even calmed me down and reassured me when I felt nervous about buying a home. She was always available and easy to reach. I would definitely go back to Karen if I need any real estate help.
