It had nothing to do with Kevin, but with the appraisal and the time it took to get to the final loan approval. We moved money into Sunflower to only have to put 10% down and then we ended up having to put 20% down. All if it seemed more difficult that it should have been. Kevin did a great job of keeping us informed and worked hard to make sure we went to the closing table in time.

Kevin and his team were amazing. This was my first time buying a home and Kevin was very patient and helpful. He explained everything very clearly and in a way I would understand. He and his team did an amazing job of constantly keeping me updated in the closing process. Everyone was very responsive and polite. They made what could be a very stressful process, seamless. You can tell this team genuinely cares for the client and wants what’s best for them.
