John Reviews


John has deep understanding and knowledge about buying / selling multi-family units. He was super helpful in finding the property, and then helping me think through what renovations were necessary for the greatest return. He will always call you back, meet you at the property, give you real life  examples, point you in the direction of other resources, and ultimately GET YOU WANT YOU WANT. I will always work with John, and if you want your real-estate to grow, you will work with him too.

I highly recommend John!!! He helped me purchase my first home in Berwyn and was professional during the process. He was always available to show me homes while answer any of my questions. I will certainly use John again for my future real estate needs. Many thanks John!!!

John is the best agent I have met for what I was looking for (Cicero and Berwyn multi units). He had an awesome understanding of the areas within the cities, the rental markets, the properties, the intricacies of how property transfers and inspections work in those towns. If a place was re-listed half the time he had seen it and could give me some info on it. He even connected me with a local landlords group which was a huge help. 

John was amazing to work with. He found me an unbelievable opportunity and was extremely knowledgeable about investment properties as well as construction. In addition, John helped after the Closing; he helped find contractors and was great at giving advice even after the sale went through. I  worked with him as a broker and as an attorney and he was extremely responsive.

John listed and sold my flip in Berwyn Illinois. It was a classic bungalow. Fine representation from start to finish. Smooth process. No complaints at all.

John help my wife and I buy our first home! He was very flexible with his schedule and knew exactly what we were looking for. We were always kept in the loop with anything that was going on or changes happening. Highly recommend John for first time home buyers!

John Warren did an excellent job for us when we purchased our new home. His communication was fantastic, he was thorough, punctual, and went a lot of extra steps for us throughout the whole process. John is a pleasure to deal with, I’d highly recommend him to anyone.

John was a huge help to us. He provided invaluable input and guidance during the sale of our old house and purchase of a new one. Thanks so much for helping this process go as smoothly as possible!

John did an amazing job helping us sell our charming bungalow. He is an excellent communicator and very helpful throughout the process. He was very responsive and has great enthusiasm for the real estate market.

John was excellent from start to finish! He worked hard to find the perfect multifamily investment property (a 9 unit in Berwyn, IL) after searching multiple areas including Chicago, Cicero, North Riverside, Riverside and Oak Park! He was very patient, knowledgeable, great negotiator, trustworthy  and extremely hard working at making the deal go through despite several hiccups on the seller’s side even during the close! If you are looking for a realtor who is reliable, trustworthy hardworking and dedicated to his clients, then John Warren is the realtor for you. Thanks for all your help John. We will certainly use you again on our next house or investment property

John was my real estate agent and helped me buy a single family home. I found his help and expertise invaluable in identifying a home which was right for me. He showed impressive knowledge of the real estate market and also what to look out for when looking at properties. We saw around 25 different  properties which gave me a very good sampling of what was available. Through all of it, John was only too happy to help. I never got the impression that he was trying to make a sale. His focus, through it all, seemed to be only that I find something which suited my budget and interest. Once we had zeroed in on the property that I liked, John worked hard to make sure that as a buyer I got a good deal in the purchase. He was professional, knowledgeable, and responsive, and I would wholeheartedly recommend him to anyone who is seeking to buy or sell a place in Chicago.

John helped me sell my condo and buy a new single family home. He had great advice that helped my condo show well and sell quickly. Throughout the whole process, he was excellent to work with and went above and beyond to make sure we found a place that would be a great fit for us.

It has been a true pleasure and privilege to work with John. From the moment we began to discuss the possibility of working together he has brought a steady and consistent focus to the process. John is very available and easy to reach. This alone means so much in a real estate transaction. He  genuinely enjoys real estate and that shows in his excellence of work. I’m glad to have worked with John and will recommend him in the future!

John was extremely attentive to my needs as a first time home buyer and helped me navigate locating a home and the purchase process. He also found excellent professionals for me to use as my lender and attorney. Highly recommend him to anyone. He’s now listing a friend’s home because they were  impressed with him as well!

John was fantastic during the many months we searched for an investment property. Being an investor himself, he really understood what we were looking for and never pressured us into buying anything. He got how we ran the numbers and would call out properties he saw if he thought it would be a good  fit. Since we were out of state John helped us a lot by visiting properties and taking pictures for use and letting us know his professional opinion if it was a good property. It took us 9 months to find the right property and John stuck with us the entire time, always giving us helpful advice on how to analyze properties. And even after we purchased our first property John continues to be a great resource for how to properly manage a rental property. I think John is one of the rare realtors out there that really does want his clients to succeed.

Working with John has been great. He is a hard worker and was very dedicated to helping us find our first multi-family investment property. He also supplied us with many good connections (inspector, lawyers, etc) that were instrumental in our sale. The fact that he also invests in real estate is  also a huge plus since he knows the ins and outs and what to look for. He was responsive, honest, and knowledgable. Thanks again for your help, John!

Could not be better: Great service, very responsive, honest, and in depth knowledge of the market, area and opportunities. He also has an amazing contact list.

I had been looking for an out of state investment property for a while and I’m so glad I found John. He was fantastic every step of the way, from sending me photos and video of each property to making copies of keys at closing. Would highly recommend.
