Attempted to rent an apartment they had available in another area (first weird clue), and I decided…read moreto cancel my booking. I was under the impression that I would be able to cancel by a certain date without penalty. They snuck in a confirmation email that they would take between ten and 100 percent deposit in a few days. Found out they would take 50% unfortunately when I saw a withdrawal from my bank account. I requested a refund when I called their number listed. The person answering said an annoyed, "Hello." ... to answer their business phone. No introduction, no nothing. Didn't know the name or role of the person I spoke with. I requested refund politely, and I received a hesitant response stating that they thought I might get it back in a couple of weeks. What a load of crap. What incredibly not customer friendly customer service. Do NOT use these people.

I am a home owner and my HOA board hired this company. TPM is unprofessional, dishonest and…read morediscriminatory. They enforce rules and regs that are non specific and therefore they can be changed like any make believe and they enforce those regs unevenly and unequally. They permit some properties to violate safety codes while enforcing the selection of garden flowers with fines and lawyers on other owners. The property manager I am forced to deal with is rude, unkind and she has absolutely no ethics or integrity and this vile company protects her. The board of my HOA, and of any HOA who employs this company should be embarrassed at their choice.

Not real professional if you ask me! Think really hard before putting anything you value in their hands.

I was comfortable negotiating terms with Vicky and Zach and I knew they understood every concern and past mistakes the new Board didn't want to repeat. Our Onyx contract is still only 4 months old but after our community town-hall tonight, The Board and and community have expressed nothing but praise for our new management company. Our files, documents, investments, and our money is respected. The quality of work contractors they have recommended and brought to us have exceeded expectations. Onyx is who you MUST use for management If you are a mindful, honest, and caring HOA Board that wants to move your neighbors to be excited, activated, and hopeful.

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. ------------------------

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: A COMPLAINT HAS BEEN FILED WITH THE BBB 6/30/21…read more I would give zero Stars if I could. SLATE negligence could have killed my son and his roommates - not being hyperbolic - gas was leaking into the house. I am cosigner of lease - 224 Wendover. Feb 2020, gas bill was $17 each; March was $130 EACH. Didn't pay b/c obviously something was wrong. Slate did not even notice the jump in the bill; My son and his roommate were waking up with headaches. Slate did nothing. My Roommate called PGW - Slate did not. PGW came and inspected all pipes and connections. PIPE ENTERING HOUSE WAS RUSTED; GAS WAS LEAKING INTO THE HOUSE. Told Slate I was not paying the outrageous gas bill due to their negligence. THEY HAVE BEEN PILING ON LATE FEES SINCE FEB OF 2020. I have lost count of how many times I've called; they DO NOT CARE ENOUGH TO RETURN THE CALLS. I wonder if this will make a difference. I am sorry for the owner of the unit, this is not his fault; Slate has been negligent and every time I think I might pay the bill, I recall how SLATE ALMOST KILLED MY SON.
