"Jan made my first time home buying experience easier and more fun than I could have imagined. She was helpful when it came to recommending a mortgage lender and inspector, as I had no idea where to begin and she listened to every single item on my wish list. She also kept me in check and didn’t let me overlook issues in a home just because I loved the bathroom, floors, etc. If I have any friends or coworkers looking to purchase homes in the area, I would not hesitate to recommend Jan. She made herself available at just about any time and made the process quick, easy and extremely enjoyable. I have been in my new home for a few weeks now and couldn’t be happier! Thank you Jan!!"

"I recently listed my townhouse with Coros-Mackey Group and Jan Mackey and could not have been more happy with my decision. Jan was an absolute pleasure to work with every step of the way. It was my first time selling a house so I was a bit clueless to the process, but Jan was there to explain every detail and walk me through every step of the selling process. Jan offered great suggestions on how to get my property sold as fast as possible which I believe helped make the sale in the end. I would highly recommend Jan and the Coros-Mackey Group to anyone looking to sell their property in the Chicagoland area."

"Jeff and Jan were referred to me by a friend, and after interviewing several agents, I agreeded they were the best choice. They were very familiar with my area, and did a great job helping me decide the best way to prep the house for sale. We had many showings the first couple days, resulting in a very solid offer within 36 hours. Most importantly, Jeff did a great job getting us from offer to close."

"Considering we had some challenges along the way, Jeff handled every situation very professionally, and through lots of unknown challenges was able to sell our home by the time requested. We would definitely tell all of our friends about the great experience we had with the Coros-Mackey Group."
