"Diana and Chris and the entire Blackman Group team are incredible to work with and I would recommend them 100 times over for their level of professionalism and personalized care that they brought to the table for selling our family's home. They are simply awesome! From the beginning, I received 10 STAR service on a 5 Star scale. They are extremely knowledgeable about the area markets and helped make a large project of selling a home for an Estate and getting it ready as easy as possible. They were my feet on the ground and they truly went above and beyond to make sure that the house was secure, cleared out, and ready for market. They completely supported the project and brought a level of care and consideration that deserves the highest praise. Every step of the way, they watched out for our best interests and the bottom line AND we even closed earlier than expected! If you are looking for someone who will work for you and provide exceptional service and care, then look no further. This is YOUR TEAM! 1000%. The Blackman Group - they are the best!"

"5 stars simply doesn't do the experience justice. If there were more stars they would get them! Diana and Chris were an absolute pleasure to hang out with. Yes that's right, I said hang out and not work with. They made our property search effortless and stress free, so much so that when they called about a property that matched our needs, it felt like old friends meeting to hang out. I looked forward to not only seeing what they had found for us, but to see them as well. At no time did it ever feel like work. They took a genuine interest in what we wanted individually and as a couple and wouldn't let us settle for anything less. They really make you feel like they had our best interests at heart. They will always be involved with any of our property needs moving forward and will always be recommended by us to others."
