If you plan to rent a property from Gressen Properties, think twice before you make a move. My…read morewife and I rented an apartment for almost three years from Scott Gressen and it was a truly awful experience. When we brought issues up... like the upstairs neighbors toilet overflowing into our apartment, we were called "meticulous". - the front steps fell apart and it took them 4 months to fix it - they never came by to mow the lawn (which we had to do) - they never did any type of snow removal (which was fine because we had to shovel our cars out, but nobody else in the building shoveled the property) - one of their guys (who bared a striking resemblance to Grizzly Adams) would come down to work and spit sunflower seeds all over our porch... needless to say he didn't clean them up but maybe that was me being meticulous - when we had water damage, instead of fixing the ceiling tiles they just spray painted them with oil based primer... which misted onto our leather couches and the owner refused to send someone out for weeks to fix it (he did take $150 off of our rent afterwards) - when we weren't home and things needed to be fixed in the apartment, his "guys" would actually eat leftover food out of our refrigerator - the power kept turning off on the property - half of the upstairs apartment was wired into our panel and we realized at the end of our lease we were paying for their electric - years prior when they "renovated" the property, they did the worst work ever (i.e., wood paneled overtop of old broken, uninsulated windows) BUT, let's not forget when one of his guys called one month to say, "Hey, I know it's a few weeks in advance but if you pay the rent now in cash, we can take $300 off." naturally that sounds shady but this was the guy we always dealt with and to save a few bucks, we jumped on it! Then when Scott the landlord called looking for that months rent, we knew we had an issue. His "guy" fled the scene and apparently quit that day and made a similar deal with a lot of the renters... too funny. That's what you get when you hire guys off the streets. These are just a few of the issues. I can't say Scott wasn't completely unresponsive, but he certainly made us feel like we were ridiculous for bringing any of those issues. Whether you are renting commercial or residential space from Gressen Properties, do your homework and determine what you can and cannot live with!

I have asked to have my office painted and after picking out the paint I wanted they scheduled a painter to paint the office. After two years I asked for new carpet. They let me pick out the carpet and had it installed. My office is as comfortable as my home office. If and when my business gets larger I hope they have space in my building or any other building they manage for my business to grow. I would even rent a residential place from them but they don't own or operate any non commercial propeties.

DO NOT RENT FROM SLATE…read more I lived there for one year and had a horrible experience. It started bad right from the start. They were impossible to reach and when you did reach anyone they would not have the answers and said they would need to get back to you but never did. Throughout my stay, my roommates and I had multiple issues. Some were fixed with but the big / costly ones were ignored. I warned Slate that I saw a leak starting on my bedroom ceiling in October. It was ignored until I called and called about it. The little leak blew up into a full blown issue. Slate never appropriately addressed the issue and kept trying to do cheap fixes instead of solving the issue. I had a leak & hole in my ceiling from October-January. There were periods where they were ignoring my calls and emails. I ended up getting a rent credit because I fought so hard and had put rent in escrow. Also the issue was never truly fixed as the girl in the apartment below me started having leaking due to the quick fix they did for mine. George is a smooth talker but do not let that fool you. He is like a politician. He may genuinely be a nice guy (although I don't think he is) but he definitely is a HORRIBLE landlord and business owner. He did not even have a valid rental license for my apartment when he rented to me. The city of Philadelphia contacted me and issued him warnings and fines. And no we did not get the security deposit back. They actually said we owed them money that they would not be pursuing. Ha! Save yourself the time, stress, and money and stay as far away from Slate as you can.

Update 2026/03/05:…read more The maintenance issue was resolved on March 2, 2026. After I posted the February 26, 2026 review (see below) and emailed multiple people at Onyx Capital Management on February 26, 2026, Mr. Zachary G., the maintenance manager, personally intervened, reviewed my video evidence accurately, apologized and took full accountability for an initial vendor error. He ensured the repair was completed promptly and followed up with professionalism. I am updating this review to reflect that the operational failure was eventually corrected. However, I am raising this review from a 1-star to only a 3-star rating because the administrative process remains a concern. The general manager, Ms. Victoria L., prematurely dismissed my concern and deleted my community post shortly after it was uploaded. She also posted a public comment stating that the lamppost had been fixed, based on an inaccurate assessment of my video evidence. Furthermore, she did not reach out directly to clarify or correct that public statement once the error was identified. While the maintenance leadership is professional and capable, the administrative side of the business still has significant room for growth regarding transparency, due diligence, and resident communication. ------------------------------------------ Feb 26, 2026 My HOA has Onyx Capital Management as our management company. On 11/28/2025 I submitted a maintenance request for the replacement of a lightbulb of the lamp post facing my rear door. As for 2/26/2026, almost 3 months later, the lightbulb is still not replaced. I sent video evidence that it is not fixed. They replied with a photo of a working lamp post, not the one that is broken. Thus far, this company has FAILED miserably at keeping the promise stated on their company website: "At Onyx Capital Management, we set the utmost standards to provide care, support, and quality to our homeowners and Board Members." I have sent multiple emails and called a couple of times. I have been patient. But this latest replay is the last straw. Onyx Capital Management's failure in this case is completely unacceptable. ------------------------
