Core 3

Fantastic experience: Thank you for always responding so quickly and taking care of maintenance issues. I really appreciate your prompt service!

Fantastic experience: The move-in experience was fantastic, as the team was very helpful. Even when an issue arose, it was quickly remedied. Brittany, a member of the team, also went above and beyond in providing support! If you are looking for an easy, no-hassle rental company to work with, then definitely reach out to Core3! Update (7/10/2026): As my family and I get ready to open the next chapter of our lives, we want to thank Core 3 for their excellent customer care! They not only provide a great living environment, but they take the time to care for the tenants they oversee. If you are questioning whether working with Core 3 for your housing needs is the right move, then do not hesitate and reach out to them! They will take care of you each step of the way, and you will find that they are a very wonderful team to work with. Thank you, Core 3 of Springfield! You have been absolutely amazing!

Negative experience: My experience with Core 3 has been genuinely awful. The unit we rented from them has lost hot water over 7 times, electricity gone out 2 times, and as of recently there has been loud banging on our door that has repeatedly awoken us (me and my partner work night shifts so need to sleep during the day) and have led ta incessant anxiety in our day ta day lives here. The hallways smells like LITERAL dog piss. The maintenance man who was let into our apartment made dick jokes ta my girlfriend, said he wasn't qualified ta work on electrical issues while messing with our fuses, and then told us the apartment had been warned about being rented out ta higher management due ta all our problems. A management just WALKED into our apartment one day because she had thw wrong room, frightening my poor girlfriend. We were promised a 50 dollar credit when the gas went out for 4 days in the building and never once saw it. Repeated talks ta management is usually led to a simple "we are working on it" and nothing else. The electrician will appear two days later (because its the weekend and they're closed) with no warning or pre message ta fix something. This has all been within TWO MONTHS OF MOVING IN. There has been no conversation about compensation, relocation within the building, or contract negotiation because they hardly answer calls. This has without a doubt been the WORST renting experience I have ever had.

Negative experience: Been trying for a week to get a response to view a couple houses. Can't even get a human to speak with. I have tried calling 2 different phone numbers, I have tried emailing. The AI bot will ask when I want to schedule a viewing, after I reply I get no response. I have tried several times. How ridiculous!

Negative experience: Most awful communication ever. I put in a maintenance request about my washer not knowing it wasnt something they would take care of. After over a week of silence I just got a new one myself. Today I get a text saying the request was canceled so when I called after getting the text, I get told the owner doesn't take care of the washer. That wasnt something you could have called and told me about a day or two after receiving the request so I would know and just take care of it? It takes 2 minutes to do to give the renter an ounce of common courtesy. Just do better.

Fantastic experience: Jeff Combs fixed my mailbox. Came right out. Communicated well. Mailbox was good as new after.

Fantastic experience: Highly recommend this property management company! They’ve been great to work with overall, and their maintenance team is especially amazing. The maintenance guy Jeff is always incredibly fast, efficient, and gets the job done right the first time. He’s also super kind and easy to talk to, which makes the whole experience even better. It’s such a relief knowing that any issues will be handled quickly and professionally. Really appreciate the great service!

Fantastic experience: Jeff Combs did an amazing job . Thank you so much for fixing my stove and my faucet.

Fantastic experience: Jeff is very efficient when doing word orders as well cleaning up behind himself.

Fantastic experience: On Easter morning my heat wasn't working I called maintenance. Jeff Combs came out within 20 minutes and fixed my issue. He did a great job. I really appreciate him coming out.

Fantastic experience: Jeff was very polite and super helpful. He did quality work and left everything just the way it was when he started

Fantastic experience: Jeff Combs good maintenance man who always does good work every time he gets a call

Fantastic experience: Brittany was amazing from start to finish! Very professional and friendly!

Fantastic experience: Jeff Combs is Maintenance Supervisor for Core3 in Springfield, IL. He is very professional, kind and very informative and on time. Did a great job replacing our mailbox!

Fantastic experience: Jeff did a wonderful job fixing my washing machine. He knew what he was doing. He was very polite and eager to help my situation. I would recommend him to anyone who needs assistance, He is an excellent worker and very professional. Thank you for sending Jeff to help me. I would recommend him to anyone who needs help.

Fantastic experience: Brittany and Heidi in the Springfield office were great and quickly responded to all my questions regarding moving into my apartment and other related aspects.

Fantastic experience: Great great service

Negative experience: Me and my partner had shown interest in an apartment, so we got a hold of this company. We went to see an apartment, it was not the one that I saw in the pictures. No big deal. I let them know the one I wanted to see. The day we were supposed to see the correct one She texted me an hour and a half prior and canceled on me so I rescheduled. The day she rescheduled for I went to the apartment and she was not there would not answer her phone I finally got a hold of the Springfield office and they got a hold of her. she still did not show me the apartment and was showing me ones way out of my price range. She kept saying she didn’t have the key so I rescheduled again. I was really adamant about getting this place but I just got a Text saying they rented it already. The communication is poor and I felt led on through the whole process. I will not be looking at any of Core 3 properties again.

Fantastic experience: Jeff was my maintenance man today for the house I rent from Core3, He installed smoke detectors today! He also installed a dishwasher for me in the past, he is always very professional and in good spirits! Core3 has been keeping my house fixed up decently as they have restaffed with better staff! Go to Core3 for your rental property needs!

Fantastic experience: Brittany was very insightful during our showing. She arrived on time and was able to answer all of our questions. Brittany was very polite and allowed us to tour the entire facility without breathing down our necks. We highly recommend Brittany for anyone looking for their next future home.

Fantastic experience: Brittany Fagan that showed us our listing arrived on time and was very polite and also answered all our questions throughly.

Fantastic experience: Excellent service

Fantastic experience: I had a great experience living in this home! While there were a few minor issues when I first moved in, the property management was quick to respond and resolved everything without any hassle. After that, I had no problems throughout the rest of my lease. The home was comfortable, and the team made the rental process smooth. Would definitely recommend!

Fantastic experience: I started renting from Core 3 at the beginning of 2022 and I enjoy the company. Catrina and Brittany are amazing. Always friendly & always there to answer any questions I need help with. I really enjoy Catrina and her genuine personality. She’s fair and treats everyone with respect. If I could give her 10 starts I would. Thanks again for being so amazing you guys it’s really appreciated. -L.S.

Negative experience: Core 3 was unprofessional and rude. Slow to respond to requests, rude and unhelpful staff. I wouldn't rent from them again. Rentor beware.

Fantastic experience: The most patient & understanding rental company I’ve ever dealt with!!!

Fantastic experience: Hard to find the new office suite after they revently moved. I have changed my recent review based on the promptness of a response from this business

Fantastic experience: Catrina really cares about her residents! Lease with Core 3!!

Positive experience: We have a 4 year relationship with this office. We chose them because of Catrina. She is knowledgeable, professional and a delight to work with. The staff is quick to answer and kind. When they don’t have the answers, they do try to get them.

Fantastic experience: I love how the members of Core 3 stay in contact with you when you are waiting for response from other businesses in certain levels. They are very helpful and were very patient being that we went through a lot of bad weather days. We were still updated every time. I thank them for being so patient and being helpful and communicating with me as much as I needed.

Fantastic experience: Core 3 understood the fees that accumulated on my account because of a communication problem and were swift to fix the issue.

Negative experience: Please never rent here my friend rented here and the leasing office is trash they are disrespectful and don’t know how to do there job they don’t send any maintenance that actually knows how to do there job everything after a month of living there has been breaking down yall are horrible I wouldn’t let my damn dog stay & any of your homes !!!

Negative experience: Not sure how they sleep at night. The worst kind of company that served slumlords I. Springfield. Sent me to a house on Martin that’s literally uninhabitable. Disgusting. And no human should ever try to live there. It’s better to sleep in ur car .. … how do they even stay. in business. Apparently lots Of unethical slumlords in sangamon . county. With any luck this company will do Society a favor and bankrupt … the kind of employee that would even work for such a commonly are equally disgusting

Fantastic experience: Core 3 was good to me. Anytime something needed fixed, it got done quickly. They were patient with me deciding on my move in, worked with me on moving out later than expected, were always friendly ..honestly no complaints. If you pay your rent on time, take care of your place, and leave it as nice as you found it..take care of them , they take care of you ..it all works out. Received a full deposit refund to. Thanks guys

Negative experience: I should have listened to the reviews! Dishwasher has been out of commission for 2 mos! Every time we get told something different. Now again it’s we need a new one! The furnace sounds weird and takes forever to get started. Would call but what’s the point! So disappointed ☹️ what is the point of paying rent if you can’t get the help you need? New year! New problem! Guess who gets to go all weekend with no hot water

Negative experience: They care more about money than they do about tenants. They're fine letting people move into a unit without heat or hot water but they'll charge tenants for everything they can think of and be rude if you need anything. Good luck getting your deposit back because they'll lie about the condition of the unit just so they don't have to give your money back. We decided to rent from someone else instead of spending another year dealing with them.

Negative experience: I didn't want it. It wasn't even for me. But thanks google

Fantastic experience: Catrina and her staff are very professional and get things accomplished in a timely manner. I have known Catrina for almost 4 years now and she takes pride in what she does!

Fantastic experience: It’s been great working with CORE3. Catrina, Jamie and Brittany make a solid team. Good communication, knowledgeable and prompt response when needed.

Fantastic experience: I've been. Associating with core 3 Springfield (Catrina) now for 2 years and I have nothing but good to say about them/her. They always take care of any problems that I have and promptly return my calls and emails. I couldn't be happier. I've had bad experienced with others in the past but not Catrina from Core3 Springfield. I recommend them to anyone... thank you. Sincerally Melissa Churchwell

Fantastic experience: I've been working with Catrina from core3 for 3 years now, and it's all been A positive experience. Catrina has always kept her word on our business dealings, she's been easy to get along with and very professional. I've worked with other property managers before, and they've been arrogant to put it mildly... Catrina is my favorite person to work with. sincerely... Mark Benson M&J Painting and FLooring LLC

Fantastic experience: Catrina and Core 3 have managed our buildings for at least 10 years. They have done a great job managing the property, especially as we moved away from Springfield and we rely on them to ensure that it runs smoothly. I text Catrina at all hours and she instantly gets back to me. I am very happy with how they handle both the buildings and our customers who live there.

Fantastic experience: Core 3 has been managing my 16 unit property for several years. They keep improving their services and response time. Catrina and Brittany have been responsive even at midnight on a Saturday night! Both provided extra mile service upon a recent insurance claim. Catrina has maximized rents and helps reduce expenses. I consider them family

Fantastic experience: I highly recommend Core3! Catrina is such a great asset to the company. She is quick to respond to client’s needs!

Fantastic experience: Catrina and staff were fabulous. Rented from core 3 for a year. Maintenance request completed timely and efficient. Office manager and staff were great to work with. Thank you so much for everything. Highly recommend

Fantastic experience: The Core3 team in Springfield is excellent. I’ve been working with Catrina for 5 years and 24 total units. During this time, Catrina put together a team, including, Brittany and Jamie. Because of these three, my properties are flourishing! An investor needs a team that they can count on and Core3 is a huge part of mine.

Fantastic experience: Highly recommend Core 3 I’ve been with them for three years now They made everything so easy and the staff is so friendly and helpful 10/10 Catina goes above and beyond and really works with me and Brittany whatever problems I have I know I can call her she makes sure she fixes them no matter what it is amazing staff I seriously can’t say enough good things.Their communication has been excellent Satisfied tenant I’m very thankful

Fantastic experience: I jus want to thank the ladies in the Springfield office they do a wonderful fantastic job i would recommend core 3 to anyone my experience with them have been a blessing Catrina Brittany Jamie u ladies are really the best continue to make the company grow in i appreciate everything stay blessed ❤️❤️

Fantastic experience: Jamie is great :) Catrina and brittany make the whole team

Fantastic experience: I rent from them love my place

Negative experience: Very poor application process. Property managers are rude and unwilling to explain anything to younger renters. They’re wasting peoples time and money and it seems they don’t really care.

Fantastic experience: I have had a great experience from core 3 .All maintenance issues have been handled quickly and office staff always answer my questions and have answered my concerns.

Positive experience: Good people easy to work with

Negative experience: I called a few times to ask about these apartments I have been watching for a long time. As soon as I asked about section 8 voucher acceptance I was definitely talked to differently

Negative experience: horrible company, NEVER rent from them

Negative experience: Slum lords, never rent from them. They don’t clean their properties upon move in. Appliances are broken, pest problems, run down property, poor management. Someone should run these guys out of business. My sister rents from them and at this rate it is way too much of an expense and a health hazard for her young children.

Fantastic experience: My property owners stopped using Core 3 as their property managers and oh man what a fricking horrible mistake that was!!!! Core 3 was responsive had some real cool handymen and always gave me good vibes. These new people are so sketch and corrupt it makes me sick.

Fantastic experience: On a professional level, Core 3 is a great property management company!!! Catrina Porter has turned the company around and I’ve heard nothing but Great things!!! From Expedited maintenance calls from a very friendly crew!! Tyler !! To name one I look forward to many years of successful business ventures with this extraordinary company!!!

Fantastic experience: I love these people Katrina and Brittany are very sweet people that have really work with me even when i struggle they gave me a lot of time hope god will bless them

Fantastic experience: Core 3 properties are an amazing Realty Company

Fantastic experience: Waiting for results

Fantastic experience: Catrina is absolutely awesome ❗️ If your searching for a place to call home you should definitely get with her she’ll find you the perfect home. Me and my family have been searching for a home for over 4 months now and literally nothing ‍♂️ Not even 5 mins within viewing one of her properties we fell in love and was placed in this beautiful home the next day. The process was so smooth and such a easy transaction. She really treated us like we were her family and we were searching for a home. Thanks so much Catrina ❗️

Negative experience: The apartment is not what was advertised. Catrina porter is responsive to messages at times but has not fixed the broken lock on the back door in months, the washers have been broken for weeks, and the building has bugs. I often do not feel safe here and I am not a sheltered person. My ceiling also leaked for months, even though a light fixture and I had to notify her(management) many times to have it fixed. The maintenance crew is unprofessional, unreliable, and not good at communicating with tenants or management.

Positive experience: Hoping to find myself a new place.

Negative experience: They are slumlords. No professionalism, no clue about customer service, unable to listen properly and relay messages, the run around for 3 days about fixing hot water heater. Sent someone with no plumbing experience, he couldn't fix it and call to emergency office number told me that they will pass yet another message along and someone will get back to me whenever. Don't rent from these people, your better off living in your car. Worthless and souless people and company!!!!!!!! Moved in August of last year. Good timing on the response though, lol!!!!!! Thanks for the update!

Positive experience: Management returned my call and I appreciate responsiveness.

Negative experience: After 2.5 years of renting with Core3, I decided to move in with my significant other and break my lease 5 months early (August of 2020). I called the office and was informed there was no lease break fee. I also emailed the office numerous times for months reminding them I was moving out. My emails went unnoticed and I was never given a move out checklist. When it came time to move out, I did so and dropped the keys off at the Springfield office. I even asked if there was anything they needed, to which I was told no. A few days after I moved out, I receive a bill for $2635. They charged me for a lease break fee, $150 to clean the baseboards and windows, $50 to clean the oven and microwave (which was dirty when I moved in) $100 to clean the light fixtures, etc. When I called the office to dispute the lease break fee, I was told “look up Illinois law” and then was hung up on. Very disrespectful. I contacted the Bloomington office who was fortunately more professional as well as a real estate lawyer in Springfield. The lease break fee was not written into the lease and Illinois law states I only have to pay for time the apartment sits vacant which they changed. I did have to pay $1500 for cleaning fees which was absolutely ridiculous. I’m a very clean person and my apartment was nowhere near dirty enough to justify $1500. Mind you, they performed this walk through without me present, without ever giving me a move out checklist and hit me with this bill after I was gone. Long story short, expect to get hit with a large bill when you move out. That’s how these property managers operate and make money! Completely unprofessional treatment of a renter who paid rent on time or early every month for 2.5 years. (Roughly $24,000 in rent!)

Fantastic experience: Great company excellent manager. Springfield

Negative experience: If I could give this place 0 stars I would. I had to break my lease due to a new job offer. Was told I needed a 30 day notice. That’s fine, I emailed and let them know I was leaving, tried calling no answer. Well the day rolls around to when I need to break my lease and no one is in the office. ON A FRIDAY! Then I tried calling Saturday nothing. They close the office at random hours and never answer their emails. When I first went to get my keys they weren’t in the office. Since I’ve been a tenant. (FEB) they’ve been through 3 office managers. And each one is worse than the last. I highly suggest spending more money and finding someplace better. If you don’t want to ever get evicted though this is the place, my neighbors were extremely loud and so much it echoed up to my apartment. I can handle a lot but when your throwing each other into walls and knocking stuff off mine in my apartment that’s too much. I made complaints on multiple occasions and nothing happened.

Fantastic experience: Always prompt to respond and fixed a minor issue the same day! Great landlords.

Fantastic experience: Very friendly and knowledgeable. Great experience.

Fantastic experience: My concerns are always dealt with promptly and professionally.

Negative experience: I'm a former tenant who decided to break the lease. I was told they'd be laundry facilities soon, NEVER. I was also told there would be A/C installed, NEVER. There was no one to clean up outside or hallways, the parking lot was riddled with trash constantly. July came, I immediately asked when the ac units will be installed., I was surprised at the response, that I'm responsible for that. I purchased a window unit... it was still hot as ever, I felt like I was gonna die, I moved several weeks later. I was never behind on rent, voiced every complaint, with no reasonable response... Don't rent from Core3, you'll regret it. Im extremely satisfied with my current landlord... They are the best! S/O to MP

Negative experience: The absolute worst property company I've ever had the misfortune to use. They will never answer or return calls, close at random times when they promise to be open for viewings, and are beyond rude. I don't know how they've kept their doors open treating buyers they way they do. April is a piece of work. She is late to listings and will not return calls on days promised, but a week from her own given date. If I could give it 0 I would.

Fantastic experience: Very helpful employees

Negative experience: When I first contacted Core 3 I was very hopeful but it quickly went poorly. After touring a rental and applying for it AND paying $70.00 to apply for my husband and myself, they say that having a large dog is a problem even though on the website it said that small and large dogs are accepted. They tell us that they will keep trying to work with the owner. We wait over a week before we give up because we never did get a final answer. In the beginning they told us that they would work with us to find a place if the house we applied for fell through. After scheduling tours for other places- they cancel the Day of and then later find out that they made the decision for us that our Large dog would not work in those houses even though the houses did accept them.. After All the B.S. - they would not refund our $70.00. I can't help but to feel scammed. There is a reason Core 3 only as 2 stars on here! They say it's a competitor making up false reviews but I'm pretty sure they are lying. I would give them NO Stars if it would let me.

Positive experience: New manager is awesome. I think her efforts made Core 3 great place to live. Earlier we felt of leaving this apartment. Now atleast the problem gets solve faster than earlier.

Negative experience: Having a hard time getting maintenance done I shouldn't be responsable for stuff that was not done before moving in!

Negative experience: Horrible everything, I was so disappointed with their service and properties. I will never rent from them in my life!

Positive experience: Have to really nag them to get things done...thats the only issue I face with them....properties are good and affordable....

Negative experience: I did not think they were helpful at all.

Negative experience: I had to call multiple times about one house. The people who answered the phone could not anwser my questions. When I called back again to speak to someone in charge I got Tara or Kara I don't really know her name because I couldn't understand her. She talked to me so rude I just hung up on her. The Springfield il office is unprofessional and rude I will never rent from these people because of this. I'm so disappointed with the management!

Negative experience: These people own North Oaks community trailer park as well as plenty of others! They are horrible slumlords to say the least!! There is mold all over my kitchen floor, the wood is literally falling to pieces, we find this out by falling through the damn kitchen!! The landlord sent someone over which took a whole week they looked at it and that's all! Haven't been back since!! Core 3 has known about this for a month now! I have a 5 year old daughter and I'm 4 months pregnant!! They have done nothing this past month to make our environment more safe!! If you're looking for a place to live, definitely find a different property manager because these people literally SUCK!!! I am fed up!! Oh and while they are taking their sweet ass time to fix what needs to be done ASAP, they were so quick to tow my car that was in my driveway for having a flat tire hahah!! What a joke!
