Tim from William Holder Realty has been great to work with. He’s definitely there for your best interest. I’m amazed at how responsive Tim and Will have been throughout my apartment search. Overall, I’m really pleased with my experience in working with Tim and Will! I would highly recommend them! I haven’t gotten word yet whether or not I qualify for a place I’m looking to rent but I’d still give these guys 5/5 stars.

Listed and sold my home in record time. Always responded quickly to any questions or concerns I had. Will explained things clearly and helped me with any paperwork I received, even delivering it to my new residence and making sure I understood what it was.
Will was more like a friend than just a realtor to us,he had our interests at heart and wanted to make sure that our process in looking for the right home was exactly what we wanted. He was very knowledgeable about the area of Delco that we were interested in living in and narrowed it down to showing us homes that would appeal to us. He walked us through the entire process from shopping to closing and gave us the right advice to make this whole process stress free. I would highly recommend Will and would not hesitate to call him again if we need a trusted realtor again. Thanks again Will.Will Wlodarczyk

William is a patient and knowledgeable realtor. We had to sell our home from out of state. I thought this would have been a stressful situation but not with William. He took his time and explained everything in detail and very responsive to all of questions. You will not be disappointed!
Moving 1100 miles away and having to sell your home is a stressful endeavor. Will made everything seamless for us! From going to bat with negotiations to meeting service technicians in our absence, he was amazing every step of the way. Thank you so much for a wonderful experience!!
William was very professional and easy to work with. He was always available to help me throughout the entire process. My family is forever grateful to William for his expertise and hard work. I would highly recommend William to anyone who wishes to have a great home buying experience.
Extremely laid back and honest. Communication is always top notch. Looks out for you as if you are a friend and not just a stranger. I could go on and on so I’ll end it with that he’s the best!
I had a good experience buying a house with William.I was nervous with getting approved for a mortgage but William set me up with the right people. I found my house after the 1st try. William sent me houses that I asked for and I fell in love with one. I’m now moved in and very happy with the decision. William made everything easy for me; I was confident and happy.
Will was very professional throughout the whole home buying process and very attenuative to our needs. He brought great knowledge on market allowing this decision to be one we felt at ease with making. If you are looking for a real estate agent whose main purpose is giving the customer the absolute best experience.
