GC Realty & Development, LLC ® Reviews

Mark has helped me over the years and I appreciate everything he has done to help support one of my biggest investments.

Thank you very much findigs specially to the agent who assisted me and my husband during the application, Ms. Catherine Quiroz. The transaction was very smooth and fast and she responds right away to my queries. Application was approved! God speed Findigs!

Catherine made the application and leasing process very easy for us! Thank you!

Catherine Quiroz was excellent! Very efficient and responsive! She made this process very smooth.

I recently moved two investment properties over to GC Realty & Development for their property management services. I really appreciated their onboarding process. John has been assigned as my main contact and he has been great to work with!

From the beginning, my personal experience has been excellent. Mark’s professionalism and calm approach have made a huge difference, especially when dealing with the unique challenges that come with Chicago investment properties — whether it’s navigating tenant issues, local compliance rules, HOA constraints, or unexpected maintenance dilemmas. His deep understanding of the Chicago market has been invaluable, and he approaches every situation with both expertise and common sense. What stands out most is Mark’s ability to handle dilemmas efficiently and with clarity, providing options, explaini…

GC realty and development, specifically Russell Wedge, assisted me with my first rental property. Russell honesty and willingness to help guided me in making the best decisions. Russell made quality suggestions to improve my property that will increase the rent I can receive. Once I complete the improvements Russell has suggested I will be using his company for occupant placement and management.

My experience with GC Realty has been great! I recently worked with John (part of Mark’s team), and he and Mark have been wonderful! We had a challenging situation with the Condo Association and with just hours away from Tenants moving in, John was able to resolve the issue with utmost patience and perseverance. Would definitely recommend GC!

GC Realty made renting out my place super easy. Everything was handled smoothly and professionally - No stress at all.

Mark the owner really knows what he's doing. He is a generous straight shooter.

I hired GC Realty to manage my property, and so far, the experience has been great. They are extremely communicative, and they are working to fill my property quickly. I highly recommend them.

Hands down the best Property Management team in the area!

Very good customer experience and great support for property owners

Glaiza is an amazing property manager. When there is something that needs to be addressed, she shows great understanding and acts swiftly to have the issues resolved. I'm also in the real estate business and was a landlord for 23 years, so I greatly appreciate someone like Glaiza who not only gets things done, but does it with kindness and care. I am updating this review on February 9 because Glaiza has been working with the unit owner (who wants to sell) to negotiate another year here. I am beyond grateful that she is talking with the owner to help make that happen. No matter the outcome,…

Edwin was very polite, courteous and helpful.

Fue muy atento, diligente y amable. Nos atendió en español, y dio respuesta a nuestra inquietud. Gracias señor Will Norris

11 months of leaks, bandaid fixes, and incompetence. Two separate leak issues were never fully resolved. Two flooding incidents left over 5 inches of standing water for over a week. Videos attached. Avoid GC Realty.

My fiancé and I were looking to move to a nicer area in Chicago and luckily we came across a listing posted by GC Realty & Development, LLC. Booking a tour was done quickly and professionally. We got to view the apartment and were both happy with the experience, so we decided to submit an application. I got to work with Catherine Quiroz throughout the application process and she was amazing! She is very professional and helpful, answered all my questions right away and made things clear and easy for us. We were very happy and satisfied with her service! Thank you!

So grateful Shania was able to have our move out date extended!

I had a wonderful experience working with Katherine. She was professional, kind, and always quick to answer my questions. She made the entire rental process smooth and stress-free. I truly appreciate all of her help and highly recommend both Katherine and GC Realty & Development. Thank you so much!

I chose an apartment managed by GC Realty a year ago when I moved from NY to Illinois. I must say the team here has always been a pleasure to deal with and very responsive. I am moving again just because of a personal need. Even in the move out process they have been helping and professional and showed legitimate care. I have been assisted by Glaiza and Pastora in this process and am very grateful.

Dealing with any contractor through GC is a nightmare. Here is my lawn, after months and months of talking about it. No follow up on a terrible sidewalk job, no follow up on mediocre gutters. Makes owning just awful.

Glaiza was very helpful and communicative

Glaiza was excellent in listening to my needs and concerns. Extremely helpful in taking care of what I needed.

I appreciate Glizas help in hearing me out and listening to help me resolve the renewal of my least at the same rent. I appreciate all her attention in a timely manner. 🙏

Glaiza was awesome and took care of everything. Made it super simple and worked with the current tenant to sign another lease. Great experience!

Catherine Quiroz was super helpful and kind through the whole (very short and straight-forward) process! GC Realty & Development allowed me to find my dream apartment!

Catherine Quiroz was so patient and helpful during this moving process <3 thank you so much!

Application process was lengthy but Catherine Q. helped us every step of the way. She was quick to answer our questions and very prompt.

Thanks Glaiza for all of your help with getting my questions answered and responding back in a professional and timely manner.

Catherine was really helpful through out the process

Catherine was so helpful with the application process, and pleasant to work with, and extremely prompt. Thank you for making the stressful process of moving that much easier on us!

I had a great experience working with Glaiza at GC Realty. She was always professional, responsive, and very helpful throughout the entire leasing and renewal process. She made everything easy to understand and was always available to answer my questions. I truly appreciate her support and excellent communication. I highly recommend Glaiza and GC Realty to anyone looking for a smooth and stress-free rental experience. Thank you, Glaiza!

Very fast and very polite! Catherine Quiroz was great to work with!

My father has been at a property for over 15 years. Has been there since the original owner (who built the building), to another landlord who purchased the building who used Katz Management, to now GC REALTY. Not only have I vacuumed their hallways on several occasions because they are filthy. No one comes out to clean the building let alone plow the parking lot when there’s a bunch of snow, do any type of landscaping, and so much more I could vent about. GC REALTY cares about one thing and one thing only, GC $$$$. You can’t even get ahold of anyone unless it’s Glaiza. Who is super kind by th…

After several weeks of unsuccessful apartment hunting, my husband and I came across GC Realty. From the beginning, they were so easy to work with and we were (finally) being treated as actual people. Catherine made the application process extremely smooth and she went above and beyond to communicate each step with us along the way. I can’t recommend this company enough if you’re on the hunt for your new home.

Update: 5 stars! I now realize that stars are gold to the company and I have to say that now, they do deserve them. I worked with Glaiza, Shania, and Natalia- who are all fantastic and easy to communicate with for all my and my daughters concerns. They have all been addressed, corrected in a very timely manner, and have gone above and beyond to make things right. I look forward to signing a new lease next year at a lower rate LOL!! But seriously, fantastic job and thank you again. I’m a tenant not a client and never hired GC they were forced upon me. So my review will be about only one person…

Working with GCR has been a wonderful experience. They have been prompt, patient, and extremely helpful walking me through all the processes. All questions are answered thoroughly. John especially, has been a pleasure to work with and always available to talk through things. He goes above and beyond to provide great service!

Rental process was very quick and smooth. I want to thank Catherine Quiroz specifically for her help with my process.

Glaiza is such a Gem, she did everything she could to make sure my woman and I were set on a path to success in terms of re-signing our lease. Thank you so much! Hope you work with us again 🫡

All I can say about my experience is: It was an amazing, a very easy process, helpful representatives. Many thanks to Catherine !

Glaiza is help me a lot with My lease renewal process and she helped me a lot in every topic that i had in last year, I am Always happy to work with her about every issues.

Glaiza was very helpful, she responded quickly and with all the information we needed.

Guaiza was very helpful in my lease renewal that I just went through answered all my questions and was prompt returning calls and responsive communication

The team is excellent. They work seamlessly together, and the staff is highly responsible. The guys always respond very promptly. We would like to extend a special thank you to Glaiza, Stefan, and Andrew, who quickly resolved a technical issue. Thank you! Wishing you all the best!

GC team members are extremely attentive and helpful. Can’t say enough about them.

After living at a GC property for 2 years, I can confidently say this is one of the best management companies I’ve been a tenant with. Mark and the rest of the team are always prompt and professional in their responses to questions and requests. Would recommend!

Recommend avoiding at all costs. In 48 years on this planet, and 30 of those dealing with rentals, I can safely say that my experience with GC Realty was the worst I've ever had. Not only were maintenance requests ignored for months, the move-out was miserable as well. Exorbitant amounts of money charged for things that were already reported to their team, charged for lightbulbs that they provided in the first place, and issue after issue that took far too long to get resolved made this one of the worst experiences we've had in Chicago. Will never sign another lease from GC.

We were tenants for 5 years with GC. Though our time leasing with them was good it was our move out experience that made us realize exactly how terrible of a property management company GC is. They took advantage of us and our situation while we were most vulnerable and my only regret is not taking them to court over all the crap they put us through. My husband got a promotion at work which had us relocate to another state. So we told GC we unfortunately had to break our lease. They responded by saying we had to pay the remainder of our lease, while was 7 MONTHS. We obviously fought this bec…

SCAMMERS - AVOID - DO NOT RENT FROM THESE PEOPLE! They will ask you to send them deposit/fees FUNDS before ever having a completed lease/contract - DON'T DO IT. Found a wonderful 1 bdrm apartment with reasonable pricing that was perfect. My daughter has 750+ credit score with rave reviews from her prior landlord. Her application was accepted and lease sent for signing - she signed - did a final walk through. The Management Company GHOSTED her when asking for a returned signed lease! She went to Chase to deposit the funds, but messaged/texted/ and called to get a signed lease first - crickets! …

Really appreciate the hard and efficient work of Jonathan in maintenance - he is thorough, punctual, and has always been helpful keeping our unit it top shape!

Best property management I've experienced. [Shania] is responsive, professional, and ensures the building is well-maintained. Safe and happy to call this place home." Thank you shania ☺️

Catherine was very responsive daily (Thank you)! Thought is was supposedly up to a 3(business day approval notification) I did a blind application before seeing the listing because I liked the area and the home listed. The Open house was 3days later over the weekend, attend with several people also attending......Starting to think my application is being held just to see how many other applicants from the open house would apply before receiving a response for my application.....😒 Edit..... Thanks for you're reply but it's funny how when I posted the review that evening the VERYYYYY next morn…

We’ve had a really good experience renting our house through Anna and her team at GC Realty. They’ve been responsive, helpful, and just genuinely nice to work with. It’s made the rental experience feel a lot smoother and less stressful. We really appreciate their support and would definitely recommend them.

Giving Jonathan the maintenance tech a 5 star review because he fixed my lock! Since moving in last summer, I have had issues with the lock/key to my unit. When Jonathan came to do the inspection in my apartment he was able to fix it within 10 minutes. Prior to this I was leaving my unit unlocked because I was always unable to lock/unlock the door due to key issues. Thank you Jonathan for resolving the issue!

Catherine Quiroz was great to deal with! I appreciate the quick communication on her part and willingness to listen to my situation. Amber was also very friendly and explained all my questions thoroughly in person. Excellent experience overall!

Thank you Catherine Quiroz she made the process quick and smooth . We are very pleased with the service and would work with the company again if we needed to

Thank you to Catherine Quiroz on the quick and timely response on a rental property! The listing was accurate and met all expectations. I would definitely recommend GC Realty and Development for future properties!

Thank you to Javier for his professionalism and guidance. He exemplifies what GC Realty stands for. I appreciate your support.

Everyone at GC is absolutely amazing! Each person we have been in contact with has been so kind, supportive and patient. Highly recommend leasing with this company. Natalia, Rica, Glaiza, Milan to name a few thank you just doesn’t seem to say enough for all you’ve done for our family.

The true measure of a company isn’t how they perform when things are easy, but how they respond when challenges arise. This review tells the story of how the GC Realty team turned a difficult situation into a win and earned my long-term business in the process. While deployed with the U.S. Army, I worked with GC Realty to lease my home. I began renting during the off-season, which made the situation challenging from the start. When it became clear that the only viable option was a 16-month lease, my heart sank, knowing that when I returned to the States, I wouldn’t actually be returning home.…

Thank you to Glaiza to has helped us with solutions to a few maintenance issues when we first moved in! She is professional, responsive and followed through to confirm the work was done correctly and promptly! Big THANK YOU!

TLDR: AVOID AT ALL COSTS! This management company is an absolute scam. I’ve rented in Chicago for nearly 20 years and have never been treated by a management company with such disregard and frankly deceptive behavior. They add fake fees onto everything, are intentionally difficult & rude to work with and made up lies to try and keep my security deposit even though I have photographic proof that they were making things up. Whatever you do, do not rent anywhere being managed by these people. It was a living nightmare.

Great experience so far working with GC Realty. John was so helpful answering my questions super fast. He kept me updated constantly while my unit was listed even through November and December when there really wasn’t even much to update me on. They got my unit rented faster than I expected and I couldn’t be happier with the service provided.

Service and communication gets a 5 star review from me! From one property manager to another (great job) solving all issues.

I know Jonathan is a very professional person, he comes in and do what he have to do ask is everything ok. He's just a nice guy.

I recently had to look for new tenants to rent out my parents’ house in Chicago. However, the former tenants left the house in terrible shape, and I knew this was more than I could handle. A friend recommended GC realty and couldn’t be happier that I’ve reached out to them. John Rosa, my onboarding manager, went above and beyond in helping us turn it into a rent ready property. It was big project at hand, as he received it in extremely poor condition and immediately put together a thorough scope of work to bring it back to life. He oversaw the remodel, coordinated every step, negotiated pricin…

This is not somewhere you want to live, trust me! I am seeing many posts about how easy & efficient the move in experience is, and it is very easy, especially those who are voucher holders. But beware, because this is all apart of their scam! I rented with GC Realty from 2023 until 2025. My entire stay there, the building/hallways had 0 maintenance work done. They NEVER cleaned inside of the building. There were spider webs and mold everywhere in the carpet. The basement where the laundry facilities were reaked of mold, and if you stay down there too long, you will definitely contract respirat…

Glaiza was very professional and efficient in getting my water heater fixed. No matter what the issue may be she handles it with the utmost professionalism! Thank you Glaiza Happy Holidays

I want to give special recognition to Glaiza in the leasing office. To be honest, I was very disappointed with my previous experiences with other leasing office staff and managers, and I felt like my concerns were not being handled properly. But once I started working with Glaiza, my opinion changed 100%. She is extremely professional, patient, and always willing to help. Every time I reach out, she solves the problem quickly and with a great attitude. She truly goes above and beyond, and it shows how much she cares about the residents. Thank you, Glaiza you completely turned my experience a…

I just want to give a huge shout-out to my property management team because baybeee… my oven was having mood swings and refused to bake my sweet pies for Friendsgiving! 😩😂 I put in a maintenance ticket, and the response time was so fast it shocked me. Before I knew it, my oven was back to acting right. Then my bathroom sink decided to join in with the drama, and fast-forward… I now have brand new faucets. 🙌🏽 I’ve never lived in a place with actual property management before, so this whole experience is new to me — but so far, they get two thumbs up from me! Special shout-out to Earl, Sal, Glai…

Tina R and the rest if the gang at GC Realty stepped up and really help us when our water heater sprung a leak. They were fast in acting and took my worries away. Thank you Tina and everyone else who helped us!!!

I’d like to give a big thanks to Shania Gilharry for helping to make this transition go as smooth as possible. I’ve been having a tough time getting used to my new normal with being recently disabled, she helped me through with all the steps necessary to transition j in to American disability act so thank you, You are greatly appreciated and I wish you a thousand years of success.

Catherine Q. at GC Realty & Development went above and beyond to help me with the application process and kept me informed throughout the day. She made the whole experience seamless! I was approved same day, after they checked my references and moving into my new home in a month. I highly recommend renting thru GC Realty. THANK YOU CATHERINE & GC REALTY!!!

I lived in a property managed by GC Realty, and while they respond quickly and communicate well, they rarely fix the problems. The biggest issue was severe black mold — not just in my unit, but in almost every apartment in the complex. I even had an inspector confirm it was black mold, and all GC Realty did was give me a humidifier instead of actually fixing the issue. That told me they didn’t care about tenants’ health or safety at all. Because of that, I see a lot of legal problems coming their way. They’ve also been unfair with security deposit charges, billing tenants for normal wear and …

The move in process with this management company was a nightmare. The unit was not walked and the home was not checked to be in working order before the move in. They do contactless move in (with no other option). Upon arrival several things were dirty and not in working order. Broken dishwasher, sink faucet sprayed everywhere when turned on, major water damage under kitchen sink, the stove exhaust looked like it hadn’t been cleaned or replaced in 30 years , broken blinds, broken screens, shower head leaks, shower faucet knob so lose it falls off, multiple outlets not working, the bedroom carp…

I have been a resident with GCReality for 5yrs. When I first moved in GCReality was taking over the property the same month I was to move in. There is major plumbing issues with this property. Yes their is areas of improvement needed that's with any.bussiness and properties. When I put in a maintenance request GCGets on it right away. Im not having to wait months. Im very pleased with all staff.

This company is really amazing. They’re understanding anytime. I’ve had a problem or needed maintenance. They responded very quickly and resolve the issues. Very quickly as well.

GC realty responds to work orders promptly and fixes the problem.

Shaker is a fantastic maintenance person. He fixed everything I needed quickly, efficiently, and courteously. I can't thank him enough for his help with the issues in my apartment. Shania G. is amazing! She is so professional, responsive, courteous, and fulfills expectations! She is the best!
