What Clients Say

In our clients' own words.

For more than 1,000 Chicago Northside clients, we've been the expert in their corner. Here's what a few of them shared about the experience.

Hire Mary Nack! She and her team were so much fun to work with, always had us laughing but at the same time were very professional and in the game at all times. We can’t make enough positive comments to detail how pleased we are. Mary is like a sister.

I just finished a closing with Mary Nack, and her clients could not have been more appreciative of her expertise. As a real estate attorney, it is not that common to witness such appreciation of a realtor that her clients had. Mary found the couple an investment property they were searching for and they remarked on her ability to find value and her savvy approach to negotiating and getting the transaction to the closing table. Mary is a great Chicago real estate agent for residential and investment properties.

I would like to share my honest feedback having recently used Mary Nack and her team (Turquoise and Lisa) at Compass. From the start, they provided me with all the information I needed as a first time seller. I was able to sell my 1 bedroom condo in Lakeview (Chicago) within just a couple of weeks. The team was extremely professional and kept me informed throughout the entire process, from reviewing comps, determining price point, organizing the open house, and handling the negotiations: It all went very smoothly and swiftly due to their diligence and commitment to high standards.

I can’t thank them enough for making this so easy and quick! You all ROCK! A special thank you to Mary Nack who also helped me buy the condo 7 years ago! It turned out to be a great profit in the end, Mary!

As a first time home buyer, finding the right realtor was essential. Mary stepped in and with her 30 years of industry experience guided me through the process, reassured me and answered all of my questions throughout the journey. It was a seamless experience! She is personable and respectful of the time you need to make the right choice for yourself. It took me a few weeks to find my home, but I ended up closing on July 21st, 2017. She recommended a lender who was stellar and an attorney. Since this was a fixer-upper she also gave me the name of a contractor. Everything is going as planned so far. You don’t just get Mary, you get a great team!

Audra E. · First-time buyerYelp · July 2017

We truly appreciate working with a buyer’s agent as diligent as Mary Nack and her team. They were incredibly communicative throughout the entire process and stayed on top of every deadline. Their professionalism made what could have been a complex deal feel seamless. I look forward to cross-closing with them again soon!

I’ve both bought and sold with Mary and she was incredibly knowledgeable in both transactions. When buying my condo she talked me out of offering too much and worked with the seller so that I didn’t overpay. I sold a few years later after moving out of state and she handled the entire transaction flawlessly. I was nervous selling while not being in state, however Mary navigated through any issues that came up and did a great job at negotiating through price and inspection issues.

Kim B. · Buyer & SellerRealtor.com

Mary Nack is the best real estate agent I have ever been involved with. She took me to see a half-dozen places in one afternoon and the very first condo we visited was the one I wound up buying. She was extremely helpful at every stage of the buying and closing on the property and was always in excellent spirits, never discouraged or daunted by any hitches, of which there were very few. Her business acumen was nearly perfect, but her real talent is her positive and unflappable personality. I give her my highest recommendation.

Michael B. · BuyerYelp · January 2011

Mary Nack recently represented me for both the purchase of my townhome and the sale of my condo. Throughout the entire process for each transaction, Mary was very professional and provided much needed and valuable insight and guidance. I was very pleased with her service and the support received from the entire Compass team.

William L. · Buyer & SellerGoogle · December 2022

Marty F. · Repeat clientRealtor.com

We have dealt with many realtors over the years and Mary is as good as it gets. She listens; she returns messages promptly, and makes appointments with ease. She has even helped us with advice and suggestions for property that is far from her home base and in which she has no financial interest. I highly recommend her.

Rosemary L.Yelp · January 2011

I worked with Mary as I sold my Chicago condo this summer. She was very helpful setting a strategy, and she connected me with a stager who was then able to secure the contractors to quickly ready my home for sale. Mary is knowledgeable, straightforward and honest. I was out of state while my home sold, and she kept me continually up to date. I would recommend Mary to anyone in the area looking to sell their home.

Erin C. · SellerGoogle · October 2022

Mary helped me buy my first building over 25 years ago. She was patient and helpful then when we were both learning and she is still that patient person that listens. Over those years we have both learned a lot. She was my agent then and still is today. She has also helped many of my friends and they pass her name on too. I have and still recommend her to buyers and sellers of homes and investment property. Mary knows the game.

Phil E. · InvestorRealtor.com

…Last spring I became a really finicky buyer hunting for my forever home - and Mary was my realtor. She knows the city by Zip Codes as well as neighborhoods and various landmarks. So we looked up and down the Lakefront, in and out of Lincoln Square, places north and far from the Lake.

Summer was over, I still was homeless and just a bit wiser after making a misguided offer. Mary has tech techniques that aided the search but even with daily doses of Homesnap and realtor-dot-com I still had no condo in my future. She was very matter of fact, not gaggy-cheerful, as she repeated our mantra: “it’s there, we just have to find it.”

Long story short, IT was there, had been sitting by the Lake since February.

Mary’s team got me set up with lender for financial pre-approval, a marvelous father-son inspection duo, and we were set to close before Halloween. Three days before the date mortgage lender called to say the deal was off because Fannie Mae and Freddie Mac did not like what they saw as a legal liability.

Mary and team involved seller’s realtor who discovered FHA would bless the deal if we jumped through a few more hoops and I agreed to pay a few more fees. We did, I did, they did and we finally closed after Thanksgiving. So Christmas in my new home was doubly blessed, thanks to Mary Nack, her team of lender, inspectors and attorney. They are a very professional team and work so well together.

Nancy S. · BuyerYelp · January 2018

Mary Nack devoted an entire year to helping us find the perfect new condo and then sell our former condo. She was well-prepared concerning the market in our chosen neighborhood and took care to research comparable properties to help us know appropriate prices for both purchase and sale. She has deep expertise on the issues related to buying and selling real estate. After a few visits to condos for sale, she had a clear insight into what we were looking for and connected us to relevant properties. Mary was always cheerful and willing to take us to a showing on short notice. Overall, we fully trusted her advice about many matters related to buying and selling. We have already recommended her services to several friends.

Carol L. · Buyer & SellerGoogle · May 2022

I just wanted to thank you (and your staff) for all the hard work you put into both sides of my real estate transaction - buying and selling. You are a true professional and a wonderful agent. The price I received for Sacramento was higher than expected. I plan on recommending you highly to all my friends and associates interested in real estate in the Greater Lincoln Square/Ravenswood. Thank you again and hope to talk to you soon!

Martin L. · Buyer & SellerRealtor.com

Mary is a consummate professional who strives to deliver and not only meet expectations but exceed them. She clearly has a passion for helping others and puts others first before her own. She is simply a delightful individual to work with and is tenacious with her drive to succeed for the client.

Eric N.Yelp · June 2017

Mary is great. Very professional every step of the way. She gets back to you in a timely manner. She is organized and helped us get our house sold fast. We strongly recommend working with her.

Carlos T. · SellerGoogle · December 2021

Mary, We love our new condo. It is perfect for us. We greatly appreciate the help you gave us in deciding when and at what price to put our former condo on the market. Selling in just a month was a wonderful surprise! We know your experience in real estate was the difference. Thanks again!

Rita & Mike S. · Buyers & SellersRealtor.com

Mary knows real estate. Mary loves to help people. Great combination! Buying, selling or renting in Chicago--or need a great referral in many other cities where one of her friends may be helpful--call Mary now. She’ll listen, and she will help you.

Steve G.Yelp · January 2011

Working with Mary Nack was a wonderful experience. Her response time was great and she was happy to answer any questions I had during the process. She took the time to go over everything with me. Mary will make sure that you know what is going on and that you’re comfortable with it every step of the way. I highly recommend Mary!
