“Working with Samantha was a great experience. Was always there to answer any questions my wife or I had and didn't matter the situation she was always quick to respond. She is very knowledgeable with not only the information you need to sell your home but finding the right home for you and your family. Constantly keeping us updated on new listings even ones that are up and coming giving you a little advantage of being the first one to view it. Very flexible when it came to viewing homes and making time that worked well with my wife and I's schedule. Highly recommend that you take the time to talk with her whether you are planning to buy or sell. Great experience for my wife and I and couldn't have asked for a better agent.”
“During a very hectic retirement and move to Missouri all within a month, Samantha Richardson safely guided us through purchasing our forever home. Her professional knowledge and caring personality was certainly a bright spot and we consider her our friend. Thanks for everything, Sam!”
“My husband and I didn't have a lot of experience with buying property. Sam was very knowledgeable and able to answer all of our questions regarding property rights. She even recommended a great local bank for financing. She ironed out any wrinkles that came up during the process. Above and beyond! I highly recommend her!”
“Samantha is a very knowledgeable, honest realtor that knows the location very very well. Very easy to work with, great communications. Welling to go out of her way to make things easier for me. I vote best realtor 2020!!!!”
“Samantha gave us an honest opinion of the value of our property and had a description and pictures posted promptly after we listed with her. Once we had an offer, she was prompt with responses during the negotiation process and getting us the necessary paperwork online. She and her office staff are professional and pleasant to work with. We would recommend her whether one is buying of selling any property.”
“She took the time to find out what I was looking for. At each home she helped me to see things that I missed, as if she were the buyer. She guided me to the exact place in which I am thrilled to live. She encouraged patience when needed and helped me to understand the market. She knows the area well and is a consummate professional, yet I felt like we were family by the time we closed on the house. After closing, she was still available to answer questions and render help when needed. If I sell my house, I will use her to help me.”
