Meet Kat Vielehr

Market savvy. Fierce negotiator. Relentless advocate.

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.

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.

Your Realtor for life.

She is really more than an agent—sometimes, it felt like she was my therapist!

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.

Where I work

Areas I serve

From the Chicago lakefront to the western suburbs, these are the places I know best.

Good to know

Common questions

Which areas do you work in?

I focus on Oak Park, River Forest, Forest Park, Elmhurst and Schaumburg in the west and northwest suburbs, plus the South Loop, Lincoln Park and Bucktown in Chicago. I've also helped clients buy, sell and lease in nearby communities.

I'm a first-time buyer. Where do I start?

Start with a conversation. We'll talk through your budget, timeline and must-haves, I'll connect you with trusted mortgage professionals, and then we'll map out a search so you always know what's next. No pressure, just a clear plan.

How do you decide what my home is worth?

I combine a detailed market analysis of recent comparable sales with a close look at your home's condition, updates and location, so the price we choose is strategic and backed by data, not guesswork.

Can you help me get my home ready to sell?

Yes. With a background in design, I help sellers decide which updates matter, how to stage rooms, and how to present the home at its best. I also have a network of contractors to call on when needed.

Can I buy and sell at the same time?

Absolutely. Coordinating a sale and a purchase takes careful timing and strategy. I've guided clients through both at once and will help you plan the sequence that fits your situation.

Do you work with renters, landlords and investors?

Yes. I help renters find the right place, landlords lease their units quickly with regular feedback from showings, and investors evaluate opportunities. Many of my clients start in one role and come back in another.

You dream it, I’ll find it.

Buying, selling, renting or investing, reach out for a relaxed, no-pressure conversation about what’s next.
