I enjoy working with both Sellers and Buyers. I have started to collect testimonials and you can read them here.

"Karen helped us through the process since the beginning answering all of my questions. Never took long to give an answer. Definitely recommend Karen if you are looking for something in the Keys. I am very happy with everything she did for us. If you need someone to trust, she is the one."

"We absolutely love having Karen as our realtor. She answered all phone calls, texts, and email almost immediately. She took care of any questions and/or issues immediately, was friendly, attentive and very knowledgeable about the Florida Keys. She lives and breathes as a realtor and that's who you want on your side from beginning to the closing. Thank you."

"Have you ever met someone you instantly click with? That is the way it was with Karen. Karen and her husband Eric stopped at one of our garage sales that we were having to prepare to sell our home of 28 years. My husband, Ralph was talking to them when I came out and Eric asked if we were planning on selling and Ralph said yes. Eric said "Well, Karen is a realtor", Karen said this that is not why she was there. We started talking and I told her that a few neighbors had shown interest in the house and we were going to try to do it on our own. We continued to talk about a lot of things and then I offered to show her the house. When they left I did get her card. A week later I dealt with Karen on another matter that had nothing to do with the house and let her know that if we decided to go with a realtor I would call her. I am chemically sensitive and having people in my house is not a good thing. If someone comes in with a heavy fragrance on it can ruin the rest of my day or even the week. After dealing with a couple of nonfragrant neighbors I realized that I couldn't be doing this myself. After being in the Keys for 42 winter seasons, leaving was not going to be easy and Karen was also sensitive to this. I called Karen and she came over and we had a long talk. I explained my chemical sensitivity and the problems I had. She was more than willing to help me with this. We had some ups and downs and a very problematic buyer. Karen was more like a friend but when it came to business she was all business and explained things very well. When we needed her she was right there, no questions asked. My husband had another realtor in mind that I knew a little bit and this person always made me feel like I was beneath her and I refused to use her. Meeting Karen was meant to be. I was more than happy to recommend her to two neighbors/friends and Karen has already sold one of the houses and working on the other. We have been thinking of making a move from MI to TN and she even offered to help find a realtor there. We couldn't have asked for a better realtor to help us sell our Key Largo Home. My only regret is that I would have liked to stay in Key Largo and continue our friendship! I wish her all the luck in the world and thank her so much for helping us through a very stressful time."

"We just closed on our house and Karen was WONDERFUL! From start to finish, she listened to what we wanted, and never got discouraged when WE didn't even know what we wanted. After 5 months of looking Karen thought we may like to view a house I had seen previously online but thrown to the side as a non contender. Once we got inside, we knew Karen had found the one! Very knowledgeable, kind, and hard working. Would recommend to anyone buying or renting!"

"I couldn't let the day go by without showing appreciation to Karen Williams, a realtor who went over and beyond to help me purchase my home. If it wasn't for her, I almost gave up, but she wouldn't allow me to give up. I'm forever grateful for her motivation and determination to help me purchase my home cause it ain't easy buying in the keys but guess (what)? I did it. Thanks to that man up above, my sister, and yours truly Karen Williams-deCastro. "

"Karen is awesome ..She came to my rescue and found me an Awesome agent... in my state... to assist my husband and I with our first home purchase. She matched us based on personality and it was an instant hit. I had been through 5 previous realtors and was at my breaking point. Karen also was available to any questions I had. Thank you so Much Karen!"

I met Karen 12 almost 13 years ago through Facebook shares about my twins born early. I didn't know then that Karen would make such a great impact on my life then. Just a friend online offering support to a new mother if twins. Fast forward 12 years. My husband and I wanted to move from Indiana to Texas. We had no clue where to start looking for our new home. I reached out to Karen to see if she could help us and SHE DID IT! She referred us to an down right AMAZING realtor in Texas. It took us time to find the house we wanted but the realtor she set us up with was very patient and just as amazing as Karen! I highly recommend Karen no matter where you live! She is a magical realtor that has an outreach to realtors everywhere!

It was a pleasure to work with Karen Williams-deCastro, realtor on the sale of our Tavernier home. If you are looking to purchase or sell in the Florida Keys or South Florida, I offer you my highest recommendation of Karen at Better Homes and Gardens Real Estate Destinations. Combined with the seamless professionalism of Coral Reef Title, this was an incredible experience all the way around! In an absolutely insane real estate market, Karen was able to navigate every single part of the transaction with a calm, cool, confident disposition.
