Mark and his team know the Chicago market. They know what buyers want, and what something should sell for. He made some recommendations on getting my condo ready for sale, which I wasn't initially planning to do, but I followed his advice and it resulted in a multiple bidder situation, at a price above asking. As for service, they are second to none. I can always get a hold of them, or get a prompt callback. I was also very happy with all the support after the offers were received. Their experience and expertise really shows throughout the entire sales process.
