"Thank You Cassidy Young & Dayna Lewis for a very smooth transaction regarding the sale of our home in Frederick, Colorado. Four Sail Realty was so very professional, with an excellent first class service. The whole procedure from signing a contract to settlement day was a worry free experience. So impressed , I was highly motivated to pursue a career in Real Estate in our new home / state of Palm Coast, Florida. I have since passed my pre license course and Exam and currently studying for my State Exam , which is scheduled in 2 weeks. Again thanks to Cassidy & Dayna for motivating me with their professional and first class service, we personally experienced. Highly recommend Four Sail Realty to anyone needing to buy or sell a home in Colorado.  In closing thank You Cassidy & Dayna very much for such a pleasurable experience, it was surely a very positive experience."

"I highly recommend anyone that is looking for an agent to go with Jason! He was very professional and is all over any questions that come up throughout the process with quick response time whenever you need him! I will work with him for future deals and will recommend him to anyone looking for an  agent! Anytime I had a question on how the sale was going or what was next in the process Jason was always quick to respond and always found the answer if he didn't have it on the top of his head. His local knowledge of what is going on in my area was above and beyond!"

-Neal E. (Erie, CO)

"Right from the initial meeting with Jason I knew I was dealing with a professional who knew how to sell a home. Answered all of my questions and even some I didn't know to ask. His calming demeanor is just what is needed in the chaotic real estate business. Jason always answered my texts promptly  (even early Sunday morning). I would not hesitate to call Jason or to refer him to my friends for any future real estate business."
