Client Reviews
What my clients are saying
“This was our second time working with Jay and the Baumgartner Group. Jay helped us sell our house in 2022 and this time he helped us find our new home. When we were ready to buy again, there was no question that we would work with Jay as he is very knowledgeable and professional. He was methodical in exploring each home with us, he points out many things that we wouldn't have paid attention to as he is truly a fiduciary agent. After closing, we had to go out of town for a week and went above and beyond by checking in on our new home (twice!) during that time. If you are looking for a straight shooter with years of knowledge, I highly recommend working with Jay. ”

“We can’t say enough great things about how amazing our experience was with Jay. He was absolutely incredible to work with. As first-time homebuyers, we had a lot of questions and nerves but Jay made the entire process feel easy and manageable from start to finish. He was always patient, responsive and reassuring. Jay’s guidance and calm presence throughout the entire process truly made a difference. We couldn’t have asked for a better realtor and would recommend Jay without hesitation to anyone! ”
