It was a great pleasure working with Debbie Collett with Sibley Realty. I could not have asked for the selling of my house and the purchasing of another home to go any better or easier. Debbie will work around the clock to make sure everything goes as good as it could possibly go for her clients. Thank you Debbie Collett and Sibley Realty for making this part of me and my family’s life such a smooth transition!

Being first time home buyers, we were a little intimidated at first, but luckily we were referred to Debbie Collett with Sibley Realty.  Debbie went above and beyond the call of duty for us, and treated us as if we were a member of her family. She never left any question unanswered and always responded promptly. She stayed the course through a very trying and frustrating selling/closing process.  She was always extremely honest with us and always made sure we were well informed. We both are very happy with our first home and couldn’t have been more pleased with the service. We are so thankful that we found Debbie to help guide us through our first home buying experience, and will only use Sibley Realty in any future real estate endeavors.

Our experience with Sibley Realty was great! Debbie was very informative and straight forward. She answered most of our questions before we even asked them. She had a thorough and professional layout ready for prospective buyers and agents in the promised time. Our house sold at the price she suggested and the closing went well also. I would recommend Sibley Realty and Associates to anyone needing a friendly, professional and quality realty company.

We used Deborah Collett from Sibley Realty & Associates to buy our “forever home.” She was absolutely outstanding. We spoke with Deborah and then met to give her our parameters of what we were looking for in buying our house. She spent hours answering our questions, providing objective opinion and data as well as tons of info on comps in several areas. She always made herself available to us even on weekends. When it came to buy our home, she negotiated all the costs to be paid by the seller as well as getting them to come down from their asking price. She explained the whole closing process and how it would work and was there in person sitting right next to us in case we had any questions. Buying a house for most is the biggest purchase they’ll ever make. For most it is extremely stressful but with Debbie I’ve never felt more at ease with a purchase. I highly recommend Debbie and the Sibley Realty Team to everyone I know. She is the epitome of a true professional and is so genuine and caring. You would be hard pressed to find a better Realtor.
