DRG is amazing. We are relocating to Chicago, and needed to sell our Warehouse District condo. Looking at the competition, we were pretty sold on DRG before we even met with them due to their services and leasing options if you don't sell.
Our agent was Mike, and he was incredibly attentive and responsive. He set us up with an excellent photographer, who even came back a second time when he wasn't pleased with the pictures, since it was a crappy day outside and didn't showcase our unit's natural light. Mike responded to emails practically immediately, and was always available for our questions and concerns.
DRG also hosted an open house in our building, since a few units were for sale. Mary (Director of Sales) hosted the open house, which got several potential buyers and realtors in our unit. Additionally, it was easy to find our unit on their website, and we had tons of showings in the first few weeks. They also employ a good service that does all the schedulings and sends feedback via email on the showing.
Our unit sold in just a few weeks, and again, Mike was great with the negotiations. We got a fair price (considering the economy), and after a kind of crappy 1st offer, we negotiated back up to about 4% lower than the list price - which was amazing. Mike even missed getting his marriage license so he could get to our closing on time, which is pretty fantastic dedication. So Mike, even if your future wife doesn't like you after that move, we certainly do.
I highly recommend DRG, and Mike Seebinger for selling your condo downtown. Despite losing lots of money in the real estate game, it was a great experience.
