  • Jason listed and sold my home

      Hhggvvhhnhffb he chendbc mdjenejdhdbebx

    • Jason and his team provide a level of service that is extremely difficult to find in the industry - better than any others I have worked with during my 15 years (and $250 million + in residential sales) in the business. He works tirelessly for his clients, is very responsive and well organized, and always goes the extra mile to make sure that his clients achieve their goals. In addition, Jason knows the Chicago market and pricing dynamics better than just about anyone that I have worked with. He is a great resource and someone that I look forward to working with in the future.

      - William, Developer
    • We noticed that you took over the listing across the street. Once your name was on the sign, we had no doubt in our mind that it would sell!! Thanks for everything you do for the neighborhood. It is much appreciated!

      - Dani and Charlie, Past Buyers
    • Choosing the right agent for your particular needs is one of the most important steps in the real estate process. Words cannot describe how lucky I am to work with Jason He is a top-performing agent, knowledgeable, professional, well organized, very responsive, and has a great personality, too.

      - Marcin, Builder
    • Jason was a delight to work with. We were not using a buying agent, yet he always treated us with respect, and we very much appreciated that. He was thorough, always got back to us right away, and we closed quickly and easily. We have already recommended him to friends!

      - Maile, Buyer
    • I have worked with Jason to sell 6 of my properties over a 3 year span. He is extremely professional and very well organized. I always knew the information that I was receiving from Jason was well researched and thoughtful. He is very capable of working with both investors and individuals looking to purchase or sell one home. I have used Jason professionally and recommended him personally as well to friends and family.

      - Past Seller
    • I've been asked a few times to provide testimonials for my peers. Jason is one of the few I'd jump to do. When I work with Jason I know the deal will be handled ethically. That's saying a lot on our field. Real estate isn't the transparent and I think Jason brings trust to the closing table. His communication skills are exceptional! Any broker will tell you that it's a key ingredient to a successful deal. Jason is one of the good guys!

      - Alley, Agent
    • I purchased a new construction duplex from Jason and had a great experience. Jason was very professional, informative and was able to assist getting the deal done quickly and addressing all my concerns. If I end up leasing or selling the unit, I would only trust Jason and plan to recommend him to family and friends

      - Past Buyer
    • Jason sold our house in Logan Square. He always got us offers, very quickly. A few backed out, but not because of anything he did. Just because they were first time home buyers. In the end, we got a deal with nightmare buyers - the kind of people Lifetime makes movies about. They tried to pull some bull at the last minute, but Jason held firm. He did not let them bully us, even if it meant he had to take them through the house the morning of the closing - after the final walk through the night before - and Facetime a plumber to explain something obvious to them. I'm eternally grateful to him, and you should use him. I strongly doubt another realtor would have pulled through for us the way he did

      - Past Seller
    • I have been working with Jason for over two years. His attention to detail, comparison skills, and loyalty to the client are as strong as anyone I have work with in real estate over the last 25 years. His ability to understand the client's program, assess potential product, assist design and construction teams, and sell completed homes at or above proforma prices is outstanding. Jason would be a solid addition to a development team

      - Past Buyer and Seller
    • I was a first time home buyer and Jason guide me effortlessly through the process. He was patient with questions and with my viewing homes for months. Jason is very knowledgable and professional and makes the process feel very comfortable. He doesn't apply any pressure to buy and really makes sure that you find something you love. I look forward to continuing working with Jason for any additional real estate transactions and encourage anyone thinking about buying or selling a home in the Chicago area to contact him. You won't regret it!
