ZillowVERIFIEDTJ hands down was the best realtor, he is also an incredible genuine person and now a friend. His responsiveness to text and emails goes beyond merit and his attention to detail, countless times he answered questions for us step by step and his dedication to selling our home and finding our next family house as we out grew the one we are in now. He is the real deal and our family couldn't be happier with what we now have.

ZillowVERIFIEDTJ went above and beyond, was incredibly helpful and accommodating. As a first time home buyer my wife and I had a ton of questions and TJ was more than willing to answer them or find someone who could. We would call TJ whenever we found a home we wanted to see and within a few minutes would have us scheduled to view it and on the same day. We really appreciated his willingness and commitment to find us a home. TJ would chat with us after we viewed a home to find out what we liked and disliked, so that he could narrow down the right home for us. At the end of our journey my wife and I felt bad at how many homes TJ looked at with us. But at the end of it all, we found the right place and are happy we chose TJ to guide us. We would recommend him to all our friends and family and will be using his talents and expertise on our next home purchase. Appreciate you!! TJ

ZillowVERIFIEDI recently sold my home in Gold Bar thanks to TJ. He worked tirelessly and was very knowledgeable. Always available to answer questions and help guide us through the process no matter what obstacles came up. He provided excellent market research of other home sales in the area to make sure the house was listed at the appropriate price point. He also help to set up a septic inspection that I had over looked. TJ was on point throughout the entire process and made this whole transaction much easier. I really appreciated his help and I will absolutely be working with him again.

ZillowVERIFIEDRandy was incredibly knowledgeable and consistently went above and beyond to support us throughout the home-buying process. There were several times he managed to show us homes while balancing family responsibilities, which speaks volumes about his dedication and work ethic. He was always available to answer questions, explain each step clearly, and guide us through negotiations with confidence. We truly felt like we had someone in our corner the entire time. I can't recommend Randy highly enoughaEUR"you'll be so glad you chose to work with him. He's not only great at what he does, but also a genuine pleasure to work with. Hell help you find your dream home!
