    Do not hire Omar and his company as a property manager. He is very unprofessional. They made an…read moreerror on the lease for a tenant expected to rent one of my properties and he put on the lease that I (the landlord) would be responsible for utilities when I clearly sent emails stating the tenant would be responsible. I called him and he started out by yelling at me and told me if I didn't like it then terminate my agreement. In addition, he didn't require the applicant to include everyone living in the house to be on the lease. I changed property management companies and he refused to give the tenant their deposit back. He was also emailing me from one of the email address and it kept coming back invalid when I responded. I was hesitant about working with this company initially but decided to move forward and that was a big mistake.

    If I could rate this business less I would. I have been dealing with this property management…read more(Omar) for over a year. Omar has consistently lied , mislead me in the entire process of me renting my home! As of date, I still have a tenant in my home, who has paid rent late and now who hasn't paid rent in almost 3 months. This entire time, Omar from Advance Property Management in the State of Delaware has neglected to send late notices to tenants but charge late fees (that he keeps) and has never filed in the local court for a failure to pay rent! There has been many, many errors, obvious neglect, and misinformation from Omar of Advanced Property Management! I'm truly distraught, angry and still in complete shock! I'm currently seeking legal advice which is going to be another expense! I warn you DO NOT USE ADVANCED PROPERTY MANAGEMENT COMPANY! This company will cause you huge expenses and refuse to properly manage your rental!

    This is the management company for the unit I rented at the River Tower, 105 Christina Landing…read moreDrive in Wilmington. I also posted a review under the owner's name to help any hapless would-be victims of this terrible company. Do not rent from these people, they are horrible. They increased my rent by $165/mo at renewal, then agreed to increase it to only $40/mo, and after we reached a signed agreement, went back on their agreement tried to bully me into signing a new lease THAT DAY for a $90/month increase. When I said my legal rights under the Landlord Tenant Code allow me 15 days to think about it, they retaliated against me by rescinding their offer to renew my lease at all. I've been a good tenant for THREE YEARS and this is how they've treated me. Do not sign up for the same mistreatment. While I was a tenant, I had to do all of my own repairs as they would not send out people to repair anything in a timely fashion. Once, the light fixture fell out of my ceiling, I reported it, and it took them over a month to put it back in. The fixture was just hanging by wires that whole time - a total fire hazard! I called multiple times but they just said they'd get to it. I've never been treated so poorly in my life; STAY AWAY!

    This has to be THE WORSE COMPANY I HAVE EVER SEEN THEY ARE UNPROFESSIONAL THEY GAVE ME A HOME THAT…read moreWASN'T CLEAN SPIDERWEBS EVERYWHERE NASTY STOVE AND acted like I just didn't pay u all that darn money for a freaking dump they all didn't communicate properly one person didn't know what the next was doing maintenance had to keep coming out for issues that should have never occurred I had to wait a month for a stove I can't wait until my lease is up I shouldve went with another company lesson learned #Buyers Beware this company sucks the house had so many issues hole in wall dirty old carpets nasty tub who would live like that I still have the pictures to prove it

    I seek out a commercial broker and was introduced to one of the partner at…read morethis firm D.W. He only sent 1 listing for the entire city of Middletown. When I inquire about other listings, he ignore me. Sent a follow email with no response. Very disappointed a partner at this reputable firm would behave this way and tone set for his staffs.

    Employees at this company, including head honcho Tripp Way, were very unresponsive, apathetic and…read moreoutright mean to me. In telephoning Tripp Way, after I found his cell phone number on his company's website, he screamed at me for disturbing his vacation, even though I was unaware of him being on vacation. Others such as Grier Wakefield, Daniel Wham and Griffin Conaty were unresponsive and apathetic to my communications. DSM had a law firm threaten to sue me if I wrote a disparaging review of my horrible experience with them. It's a shame they're not familiar with the U.S. Constitution. Lastly, they refused to deal with me in 2025 because I left them a negative review 4 years prior when their employees were just as apathetic and unresponsive back then. As a result, I feel that the culture at DSM is very retaliatory toward their clients at the property owner's expense. In addition, if you look at DSM's website, you'll see that each of their team members are pictured. There are 36 total team members, and only one MAY be someone of color. Also, out of the 36, only a third are women. What does that say about DSM's hiring practices? I am a woman, and when I TRIED to be a DSM client on 3 different occasions over the course of the past 4 years, I felt undervalued and dismissed each time!
