Relocating from CA to MO couldn’t have been an easier thanks to Cassie, Kearstin and the team at the Flanagan Group! They have been wonderful to work with from the very first call! Referred us to our amazing lender, always ready and available to show us a home we wanted to see and helped us understand every part of the buying process considering it is much different than in CA. Thank you for making this such a seamless process!! ❤️

Cassie, Courtney, and Kearstin were absolutely phenomenal to work with. Helping us navigate through our first home buying experience was crucial due to some hiccups, but they explained every process in detail of what to expect. The timeline was spot on and they were always responsive to our questions immediately. I cannot recommend them enough!

Wonderful team to work with. Shaylea was helpful in finding just the right investment property. When she wasn't available Kirsten was always there for us. Courtney was super responsive with making sure all the I's were dotted and T's crossed! Highly recommend using The Flanagan Group!

Words can not express how deeply grateful we are for this company. Shaylea, Courtney and Katie were so helpful to us no matter what time of day or night on finding our dream house and helping us navigate through all the paperwork and ins and outs . They were kind, professional and courteous and went up and beyond any other company I have ever worked with. In my opinion they are the best real estate group in Missouri and if you want someone that really works for you and puts your needs first, this is the group to go with.

Shaylea Brown was amazing! She was very helpful, accomodating and patient with us, as we searched for the “perfect” home from April 2019 to finally making an offer on February 2020 and eventually closing on 3/20/20. She went above and beyond for us, addressing our concerns with immediate action and responsiveness , answering our questions honestly, even if it was just random inquiries when we would shoot her a text or call late in the night. Her assistant Courtney was very helpful as well!
