If anyone in Miller or anywhere for that matter is looking to buy or sell a home, I highly recommend using Coss Agency, Inc.. They helped us get moved home. They made it such an easy and flawless transaction. They were so easy to work with and took care of any issues that came up. I have dealt with a few realtors and I would highly recommend them. Thanks Kendra and Dan – Deb K
