Broker Associate

A native Chicagoan, Mark Jak always considered Chicago his very own backyard. A proud Lincoln Square/Ravenswood resident for almost 20 years, he has a complete understanding of the uniqueness and richness of each neighborhood on the north side of Chicago.  His clients often rely on his knack for tracking down the best, most affordable, tastiest, or friendliest spot in the area.

Real estate came naturally as his family started rehabbing and selling homes in the Chicago suburbs since he was five years old.  They also realized that he was more adapt using a pen than a hammer and for his own safety asked that he put the hammer down.  Prior to entering the real estate profession full-time in 2003, Mark had a successful 14-year career in telecommunications with a Fortune 50 company. His successes include working with a team that earned the JD Powers Award for customer satisfaction. Prior to entering the work force Mark received his B.A. in Art History from the University of Michigan.

He finds that his creativity, diplomacy, and analytical skills have given him and his clients and edge in the ever changing real estate market. His ability to see beyond facts and find the motivation has assured the best possible value for his buyers and sellers.  

His buyer’s appreciate his ability to temper their excitement with patience to help obtain the most value for the home of their dreams during the negotiating stage. He is one of only 2% of Realtors who hold an Accredited Buyers Agent designation.  In addition, once his clients move into their dream home they know they can and do call him years after the transaction to get advice on renovation projects or other home ideas. Mark is also a certified as a relocation agent assisting many clients transferring in and out of the Chicago area. 

Sellers appreciate Mark’s ability to promote their home to the most qualified pool of buyers.  His staging expertise has been featured in a Realtor magazine cover story and video. Mark believes that in our techno-savvy market his client’s home must present itself on-line in the best possible manner to draw in buyers.  Most sellers don’t realize that when a buyer walks in the home they are validating what they have read and seen on-line.

Mark is an active member of the community. He is on the board of Edgewater based Neumann Association, which helps individuals with disabilities by integrating clients into the community. Through his volunteer efforts he received the 2008 Volunteer of the Year award from ARC Illinois. Mark is also a proud member of the Lake View Rotary Club and a member of the Lincoln Square Chamber of Commerce.  When he is not working or volunteering he spends time with friends in Chicago and at his cottage in Southwest Michigan, playing tennis, walking his pugs, and reading.

This was the first time selling my house and Mark Jak was absolutely wonderful!  He took the time to answer all of my questions, was always prompt in returning my calls and emails and made excellent recommendations that would increase interest in my condo.  After putting it on the market we accepted an offer after 2 weeks!!  I could not have done it without Mark nor would I ever consider working with another agent.  He's the best!

I'm sitting here in my beautiful new condo and only have Mark to thank for being so helpful.  My husband and I were working with a tight timeline and we had some bad luck along the way but Mark made the process go as smoothly as possible.  He was responsive and informative and is easy to work with. I appreciate that he would give us space to make up our own mind about a place while providing objective information about it to help us decide.  I never felt pushed into anything and I felt like he had our best interests in mind when providing his own feedback.  We had some specific (maybe a little picky) criteria for our home and I felt like he paid attention to that and didn't show us anything that would have been a bad fit.  The process ended up taking longer than expected but Mark found us our perfect home in the end and we love it!  I would definitely recommend working with Mark.

Mark Jak won our business in a competitive process arranged by our relocation company, in which we interviewed multiple potential realtors.  We were unanimous in selecting Mark to represent us as sellers, and now that our transaction has closed, we know we made the right choice.  The reasons we chose Mark were the same reasons we were so satisfied with his representation:  he provides reliable, candid, straightforward and evidence-based advice.  He is also proactive and very responsive.  He was in touch with us just the right amount so that we knew our property was important to him.  He also did extensive homework before our initial meeting, which diligence impressed us immensely.  He also came with market specific location specific ideas on how to market the property.  He was a breeze to work with, and at the end of the day, delivered results.  We wholeheartedly recommend Mark.

My husband and I are now first time home owners thanks to this man!!!  We didn't know where to begin or who to talk to, we were completely new to the entire process, all we knew is we wanted a home.  Good friends of ours highly recommended Mark Jak with Baird & Warner, they bought with him 2 years ago and had nothing but kind words to say about him. We met with Mark 3 months before even wanting to begin our house hunt and he took the time to explain everything thoroughly and he patiently waited for us to let him know when we were ready to start making moves.  Mark was never pushy, always patient, nothing was ever a stupid question (because I had many!) Even through the MANY inches of snow, the NEGATIVE temps and INSANE wind chills Chicago had this past winter, Mark was ALWAYS available to show us houses and he was super easy to schedule with.  He was always punctual (even throughout ALL the snow), he always replied to emails/calls/texts in a timely fashion and he really does give some great real estate advice. Thanks to Mark we now have a beautiful home to call our own!

I was a first-time buyer and Mark was very helpful and patient. He showed me properties in a variety of neighborhoods and helped me clarify what was important to me. I felt guided by an expert'. M Borysewicz

'Mark is well organized and highly professional. He is a good listener and worked to understand my needs, which focused our search. His knowledge of the city and real estate is exceptional and in the end found me the right home at the right price'. J McGill

'We wanted to buy a place in Chicago; we wanted to find it in 3 days, since we lived out of town. We did many long-distance searches with Mark before we got to Chicago. We found Mark sensitive to our needs, his patience only exceeded by his expertise.' D Cody
