Penny was outstanding to work with! As a first time home buyer she guided us through the buying process and ensured we were educated on all fronts before committing to signing. She was kind and knowledgeable and I am so grateful to have worked with her to find our dream home. Thank you so much Penny! ☺️

We absolutely love working with Penny. We’ve sold and purchased multiple homes with her over the years, and every experience has been better than the last. Penny is knowledgeable, patient, and always makes us feel fully supported. She handles every detail with care and communicates clearly through the entire process. We trust her completely and wouldn’t work with anyone else. Highly recommend Penny and her team to anyone looking for a truly exceptional realtor!

We had a wonderful experience with Penny on selling our house. Everything went smoothly and we were happy with the sale.

Penny is the best agent you could possibly work with. She was the one who originally found us our condo and, even with so many offers on it, she managed to score it for us. At the time she told us it would be a great investment that would grow in value and she was absolutely right. Fast forward to selling, and thanks to her knowledge of the market and effort, we ended up getting the highest valued sale in the whole complex. We didn’t even bother looking anywhere else for an agent because Penny is all you need. She’s smart, hardworking, and genuinely cares about her clients. Couldn’t recommend her more!

Update - we also bought our next house with Penny, who found a listing with the exact layout we wanted in our target neighborhood!

--

Penny helped us sell 10% above list price a few days after listing, selecting from over 20 offers and a half dozen competitive offers. With a unique modern house with various improvements, there weren't many similar homes in our area. We wanted a realtor who could draw buyers and establish the value of the house above the comps, and Penny helped by recommending contractors to fix a couple minor items and get the house looking its best. She also arranged professional photo and video. We had a large crowd for the open house and fully booked showings from when we listed until going contingent. Closing went smoothly.

Penny was an exceptional realtor who made selling our home a smooth and successful experience. She gave us thoughtful advice on pricing, coordinated beautiful staging, promoted our home through social media, and even organized previews for other agents before the open house. Thanks to her strategy and hard work, we received multiple offers right after the first open house and closed above asking price. Penny also handled negotiations skillfully and was always available—even outside regular business hours. Although we had already moved out of state, she tracked everything for us and kept the process on course. We’re so grateful for her expertise and highly recommend her to anyone looking to sell their home.

What do i like about Penny: tells the truth, admits if she doesn’t know something. Always there to take care of things. I can tell Penny cares and does best to underpromise and overdeliver.

this is also a like, and also a dislike: straightforwardness and honesty. Can upset you with truth if not in the right mood.

My home is sold, and she took care of my trash when i was out of state.

Five Stars for Penny!

Penny has been a trusted realtor in my family for years, and now I truly understand why! From selling my old home to helping me find the perfect new one, she was with me every step of the way. Her bubbly personality made the entire process feel less stressful and even fun at times.

What really impressed me was how well she communicated—not just with me, but with other realtors. She knew exactly how to advocate for what I needed and kept everything moving smoothly. She helped me narrow down my search quickly and zero in on a home that checked all the boxes.

Penny is knowledgeable, responsive, and genuinely cares about her clients. I felt confident having her on my side, and I wouldn’t hesitate to recommend her to anyone buying or selling a home. She’s truly a gem!

We hired Penny in February to sell our home in Naperville. She went above and beyond every step of the way. She helped us get our house ready for listing by sending over a staging company which was so helpful! She also created an amazing marketing video of our home that really highlighted our house and the area. Our house was under contract only a few days after we listed because of her experience and her knowledge of the area. We would definitely recommend Penny for all of your home buying/ selling needs!

I do not know where to start. I have bought and sold a half dozen homes, but I have NEVER experienced a real estate agent like Penny O'Brien. She is amazing!! From Day 1, with her initial walkthrough suggestions, she knows what the market wants and guided me through the process. The team she has to support sellers throughout the preparations for sale all the way to closing were professional, timely, and very reasonably priced. The video she produced in advance of the sale whetted the appetites of buyers and their agents even before the first open house. The house sold the first weekend it was shown and at a price well above asking price. Thank you, Penny, for making the selling process painless and quick. You were a blessing to me and my family. God bless you!!

Penny sold our house the first weekend it was listed! She is fair, honest, and knowledgeable. She also works with a great group of people which made our whole experience seamless. We liked that she is local and really understands Naperville. From our first meeting with Penny to having an offer on our house, was just two weeks. We would highly recommend.

Penny did an extraordinary job. Her advice and counsel on preparing the house (from what to spend money on to position the house for rapid sale at the optimal ROI - to suggestions on staging the house to showcase its best features) was invaluable. Her connections to all the best local vendors for painting, electric, landscaping, etc, saved us significant time/money because we got the right people on the first shot. And her knowledge of the local real estate market and “feel” for what the optimal price and timing to list the home would be turned out to be “bullseye” perfect. She is a real pro, we were in good hands.

Penny was wonderful to work with! She provided us with resources to find homes even before they came on the market. Our search for a new home did not take long and we were able to finalize it very quickly from search to closing. Even after that we've bought the house, she continues to be a great resource and provides us with contacts of contractors for all our maintenance needs. Best and very hands on Realtor.

I have worked with Penny twice. She goes above and beyond to make sure everything goes smoothly. She handled all interactions while we were moving and setting up out of state. She is spectacular and knows her stuff. She was always available to answer questions and she even did some outreach for us in our new state so we could purchase property on arrival. Highly recommend Penny O'Brian!

We actually started the process of selling our home 8 months before it was actually listed. Penny came over, walked through our home and offered many helpful suggestions. The minute she left we started on her recommendations. While we had not signed a contract with her yet, she was always available whenever we called with questions.

Fast forward to us listing our home. Our house looked wonderful when we listed it. It was a clean, a well maintained home but Penny's expertise took it to the next level.

By the end of the first weekend it was on the market we had multiple offers all over asking price! It was a team effort however, we could not have done it without Penny's guidance.

Selling a home and moving can be stressful...Penny made it much easier for us! We are very glad we partnered with her to sell our home!

Penny is a true professional who really understands the Chicago area market. This was especially helpful when my family had to sell a home as part of an estate. She was there for us each step of the process of getting the home market ready, advising us on timing and pricing, and walking us through the multiple offers we received the first weekend. She also checked in periodically until closing to make sure there were no problems that could cause a delay. I would recommend Penny to anyone needing a smooth home selling process!

Selling (or buying) a home is so nerve rattling. We were lucky to have Penny hold our hand through every step. She coached us through the whole process and got us the right price.

I knew very little about real estate and had no idea what was involved when it came time to sell our home. Penny's ability to establish rapport and trust with us was excellent. Penny has a lovely, positive, can-do attitude, and listened to my husband and me. She asked intelligent questions. Penny meets her clients where they are. She could not have had better communication skills and was able to navigate each step of the process with each member of the selling, and purchasing team. Her fun personality and her in-depth use of technology made her marketing particularly efficient. Her years of experience, and extensive knowledge of the market, allowed her to price our house expertly, in tune with the market. Much paperwork was involved, and Penny reviewed each document with us until we understood what we were signing. We can not recommend Penny highly enough. We had a wonderful experience
working with her.

She is very responsive, returning calls promptly and making sure you see homes the day they go on or the next day.

Our selling process from the day we met to the close of sale was totally smooth. I cannot believe how in tune to the market place Penny is. She really knows the market condition and is very professional. I simply cannot say enough about Baird Warner and Penny O’brian team except “Wow”!
Penny got us well over asking price and sold our home essentially with in hours of it hitting the market. When it comes to higher end or mid range homes she is the best. Thank you Penny for all that you did for me and my family.

Penny was an amazing listing agent AND selling agent. She is named top realtor for a reason. We viewed our dream home & knew we wanted to make a move, without even having our house ready to sell or on the market. But, she made it happen! She dropped everything that evening to provide feedback on what we needed to do to get our current home on the market ASAP. She is professional & knows the market - once we listed our house, we sold very quickly and then put an offer on our dream home, which was accepted - it worked out perfectly. She is fantastic at her job and continuing to support her clients beyond the sale!
