Meet Kat Vielehr

Market savvy. Fierce negotiator. Relentless advocate. Your Realtor for life.

Kat Vielehr

Real estate is about so much more than buying and selling homes. It’s about making smart decisions, recognizing opportunities, protecting your investment, and having someone in your corner who will fight for your best interests every step of the way.

I’m a data-driven real estate broker specializing in residential properties and investment opportunities throughout Chicago and the surrounding suburbs. I believe that knowledge is power, and I rely on in-depth market analysis, strategic pricing, property valuations, and a strong understanding of local market trends to help my clients make confident, informed decisions.

But numbers are only part of the equation.

I’m a strong negotiator, a tireless advocate, and someone who isn’t afraid to roll up her sleeves and get her hands dirty. Whether that means preparing a property for the market, identifying hidden potential, navigating a difficult negotiation, or finding creative solutions when challenges arise, I’m all in. I don’t believe in doing the bare minimum, and I certainly don’t believe in giving up when things get complicated.

With a background in design and an eye for detail, I help sellers see their homes through a buyer’s eyes, identifying the improvements that deliver the greatest impact. From small cosmetic updates to thoughtful staging and strategic marketing, I know how to position a property to stand out. And with a trusted network of contractors, lenders, inspectors, and real estate attorneys, my clients have an entire team of resources behind them.

After spending 16 years living in Chicago’s South Loop, I now call Oak Park home. My love for architecture, neighborhoods, and the unique character of every community I serve runs deep. From Oak Park, River Forest, and Forest Park to Chicago’s South Loop, West Loop, Near North Side, and beyond, I bring both local knowledge and a genuine appreciation for the places people call home.

Outside of real estate? I’m a proud mom, a lover of travel, incredible food, and beautiful architecture. I’m happiest exploring a new destination, discovering a great restaurant, baking something delicious for the people I love, or chasing the sunshine whenever I get the chance. I love entertaining, bringing people together, and giving back to the communities that have given me so much.

At the end of the day, my goal isn’t simply to close a transaction. It’s to build lasting relationships, earn your trust, and become the person you call whenever real estate is on your mind.

Because to me, you’re never just another transaction. And I never want to be just another Realtor.

Let’s open some doors together.

What clients say

Kat has helped me with several real estate transactions, including both the sale and purchase of my homes, and I have been extremely grateful to have her in my corner. As a seller’s agent, Kat is incredibly diligent. She does her homework and obtains all the necessary market information and statistics to make sure the property is priced appropriately. She also connects you with the right professionals to prepare your property for sale in the most economical and budget-friendly way, while making sure it is positioned as well as possible for pictures and showings. She is also great with social media and knows how to market a property. It is absolutely worth hiring Kat as a seller’s agent because she will work hard to get you the best possible price. She is always there for the showings, holds open houses herself, and advises you throughout the entire process. She is really more than an agent—sometimes, it felt like she was my therapist! As a buyer’s agent, she has the patience of a saint. We were looking for my most recent house for over two years. She never once expressed frustration or lack of interest. She approached every potential property with the same energy and enthusiasm as if it was the one. She encouraged me not to compromise and to keep looking for the property I actually loved. She was always available, often on a moment’s notice, to view a property and made sure I could get in the door quickly. She also maintains good relationships and communication with other agents, which helps position your offer in the best possible way. And after two years of searching, I finally found the house that I am in love with. It is, in all respects, perfect for me—which is a rare thing in real estate. I am very grateful to Kat for sticking by my side throughout such a lengthy and difficult process. She is diligent, patient, knowledgeable, responsive, and genuinely cares about getting the best outcome for her clients. I would highly recommend her to anyone buying or selling a home.

Kat represented us very well during our real estate sale process. She offered us a realistic market analysis / value, prepared our property for showings and within a week we had multiple offers. Kat ensured that the post-offer to final closing deadline was adhered to and was always available whenever we had doubts to clear. Overall, our experience has been very positive.

Katerina “Kat” is what you want and need in a real estate agent to sell or buy a home in any market, and especially in today’s competitive market. Super responsive, professional, organized and a great communicator. Detail oriented, including putting the finishing touches on my house prior to listing, which then led to a fast sale. She was recommended to me and I quickly found out why. I absolutely recommend her for anyone looking to buy or sell. She is now my “go-to” agent and person for all things real estate and I will enlist her services in the future without hesitation.

Katerina was beyond helpful in my time crunch to find an apartment. I had 30 days and had been searching for months on my own. Katerina was the only realtor to ask me what my situation was and really advocated for me to get the apartment that I really wanted to get. She was on top of everything and followed up a few times after I moved in to make sure I was doing ok. I had a few issues and she helped me get them addressed. Her knowledge of the area was helpful as I have a small child, and she was also professional.

Kat helped me with both the sale of my downtown luxury condo and the purchase of a townhome in South Loop. She is a stellar seller’s agent. She helped me tremendously throughout the sale process, beginning with the necessary updating/remodel. She recommended trusted contractors, was there to interview them when I was not available, and provided helpful design suggestions. Once the condo was listed for sale, she did miracles: she brought multiple offers in a challenging market, and ended up selling my place for $70K over the initial asking price. I truly believe that, without her, I wouldn’t have had the stamina and motivation to sell the condo where I had lived for 20 years. And I wouldn’t have sold it for that price. Kat also was extremely responsive in the process of finding my new place. She answered every text (some of which were quite emotional), she always kept her cool, and was great at negotiating. Kat is a 5 star real estate agent. I recommend her highly.

For years I have been planning and working on moving to Schaumburg for my son. I had a lot of wants. A strict budget. I am in sales myself so… a nightmare client. The real estate market was the most difficult I may ever experience in my life. Kat to the rescue! She put up with me for months and we found a home that my son and I never imagined we'd have. It has it all and then some, and she even guided me on making it better. Buying a home is not an easy task but if you have Kat on your team, you'll want to buy one every chance you get. Thank you so much for being amazing! Till next time…

We can’t say enough great things about Kat because we may not have been able to sell our condo if not for her tenacity and dedication. The process started easy enough with an initial surge of offers (which we credit to the incredible photos and presentation of our place by Kat and her team). But then things got difficult with troublesome inspections, unreasonable appraisals, an offer that fell through, renegotiating with previous bidders, and finally pushing through a rushed close date to accommodate both parties. She was there to guide us every step of the way, through both the good and the bad, and provided excellent advice and contacts who made the process easy to understand. We’ll definitely work with her again in the future and would strongly recommend Kat to anyone who is in need of a realtor.

Kat worked with us to both sell our home and find a new one. She is the best of a long list of agents I've worked with in real estate over the last thirty years. Kat is smart, savvy, responsive, and strategic. Her patience and open-minded approach helped us to make the best decisions on both properties. I cannot recommend Kat enough! She's the best!

It was an absolute pleasure working with Katerina. My husband and I just bought our first home in Riverside and we were so incredibly lucky to have Kat looking out for us. She was organized, thoughtful and really took the time to address our needs and concerns finding a home. We're so grateful for all her help and 100% would recommend her to anyone looking to buy a home!

What a pleasure to work with Kat during our recent search for a new apartment in Oak Park! She's patient and professional but very fun and enthusiastic, and has a great eye for detail and design as well. Kat helped us quickly and efficiently find a great flat, by taking our list of requirements and narrow price range, identifying a wide variety of possibilities in Oak Park, River Forest and Forest Park, and arranging showings that worked within our limited time frame. She provided great guidance in looking objectively at the pros and cons of the places we were interested in, steered us away from a few places that would have been a waste of time, and ultimately, helped us land the ideal new place. We'd highly recommend Kat as a great agent for buying, selling, renting, or leasing!

Katerina was extremely helpful and responsive to getting my unit rented. She let me know when people were coming to look and gave me their feedback to help make future improvements. She has great communication and positive energy. I highly recommend working with her and you will get the results you're looking for in the end. My unit rented fast and I have plans on how to make it more accommodating next time around.

Katerina was wonderful to work with and took all the stress out of trying to find a renter for my unit. She informed you on feedback from potential renters for future improvements on the unit to make it more appealing. She also kept informed when there were people that were interested and aided in the whole process. Highly recommended!!

This was a complex sale and Kat handled it with grace, patience and professionalism every step of the way. There were many twists and turns that she navigated with grace until closing day. It wouldn't have happened without her efforts. Local knowledge, process expertise, responsiveness and negotiation skills: all five stars across the board.
