The Hummel Group is a great team! We have worked with Kelly for the past five years on several real estate pursuits and have been very happy with the results each time. He listens well to what we're looking for and doesn't try to push us on anything. He's also super responsive, which is so critical when we're in a time crunch in a hot market. I'm excited to see his team growing and following in Kelly's great approach to real estate.

The Hummel Group did a fantastic job selling our home. The team worked together to make our experience a pleasure at a very stressful time. Our agent came to us with a plan on how to sell our home and stuck with that plan. Within 2 days our home was under contract with a very good offer and closing was completed right on schedule. We enjoyed working with this group and highly recommend them. Thank You Hummel Group Team!

I highly recommend the Hummel Group for any real estate needs, whether it be selling your home, buying a home or for investment real estate needs. I recommend them because I have used them for each of these. Kelly was extremely professional, did exactly what he said he would, saved me money on my home purchase and has helped me purchase numerous investment properties. I can not speak highly enough about the team!!
