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.

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.

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

DelVal managed my property (1 unit) for 6 years *Price…read moregouging and nickel and dime-ing *Failed to make for smooth transition from one tenant to the next Example of prices plus: 1. Quote to make my place ready for new rental was $1,215 more than the price quoted by the management company I have since moved to and who has stellar reviews. Some items in the quote were clearly unnecessary, in my view and, apparently, in the view of the management company I've gone with since there was no mention of "ripping up carpet," for example. 2. Over 3 times more to renew my rental license than it would cost me to do by myself (which I have done every year). $70 versus $283 3. $180 to "supply and install" 3 smoke alarms. (By the way, 3 functioning alarms were there on the bannister. I was charged $95 to go to the unit to turn off one that was going off. 4. $200 to remove items left in closets and "haul to dump." Note: one item was a portrait of me when I was a child and the other items were photo albums. No questioning of whether I or the previous tenants wanted these items that clearly were personal. They knew that the previous tenants were my family members. Regardless, I would think that one's first instinct would be to see if family photo albums were left by mistake and to see to whom they belong. 5. $150 to inspect my property after the previous tenants vacated 6. $125 to replace a handle on a sliding door to the indoor balcony 7. No reports emailed to me (as other management companies that I have researched do) and a portal that does not at all make the reports easy to read. Indeed, I had to ask for a report to be run for what I needed to file my taxes. 8. An attitude of my place looking nearly like a dump when the person I am going with said it was a nice place (including a functional fireplace) with not much work to do to make it rent ready--painting was the main thing, which DelVal also said but, again, at a MUCH higher quoted price. Instead of seeing the dirt on the steps that lead to the unit as "normal wear and tear," DelVal's inspection saw it as "damage." These are examples. I very quickly learned to simply take care of matters myself. As I recall, it was going to cost 2 or three digits to replace an air filter, for example. The mark-up for repairs and maintenance is 20%!! Other management companies with reputable reviews and with years of experience charge anywhere from 0 mark-up (they have their own General Contracting Company) to 10%. In doing my personal research, I have found no other company to charge a 20% markup. Lack of Smooth Transition: For example, no arrangements were made with the tenants who were leaving in terms of keeping the gas on (putting it in my name) or changing the electricity into my name. Again, I am taking care of these things, including having to travel 2 hours to wait in person for the gas company to turn on the gas. Bottom Line: A landlord can do MUCH better without DelVal and with another management company.
