“Our home sold in less than 2 days, during the coronavirus pandemic! Sale price was over the list price! Virtual presence was key to its sale and they did not disappoint in the pictures, styling recommendations, etc. Overall a very positive experience. Highly recommend working with Mr. Mulligan.”
Karen Groething, Silver Spring, MD (Seller)
“I recently worked with Bill Mulligan for two real estate transactions (buying & selling). He is a great communicator. I was impressed with Bill's ability to engage and locate a buyer for my property on a timely basis, especially given what's going on in the real estate market with COVID (a difficult sales environment for sure). There was a prospective buyer after the first open-house, and Bill followed through to keep the lines of communication open. Bill is knowledgeable about the local marketplace, and is clear about expectations & steps required to make a transaction go smoothly. Bill also went above and beyond to become an expert regarding the details of Montgomery County's MPDU Program, meeting and communicating with county representatives to understand the county's financial interests in my property and process requirements to complete a sale. It was a pleasure to work with Bill on both transactions, and I'm sure to recommend him to friends and colleagues looking to purchase in the DC Metro area. Also, I noticed a similar property down the street from mine (on the market sooner and offered by a totally different realtor)...yeah, it's still for sale. That speak volumes about the level of effort Bill put into getting my property sold. Many Thanks!”

“Bill provided exceptional guidance through out the transaction from staging through settlement. He was always there to step in and problem solve big and little issues taking them to successful conclusions and off of our "worry" list.”
Pat and Diana, Washington DC (Seller)
“Bill was very knowledgeable and engaging. He understood my needs and did his best to meet them. He was also very respectful and understood he was selling my home not just another unit. I had spoken with a so called expert on this building and found her to be snooty and not as knowledgeable as Bill Mulligan on a very important aspect. I would recommend Bill to anyone and especially to someone in the building. ”
Colleen Kane (Seller)
“I was lucky to have Bill as my agent. He proved me that it was the best because he was always there whenever I needed him to clarify things I didn't understand as a first time home buyer. He taught me a lot of things. I will recommend him to all my friends and family members. also appreciate Melanie Bramble for her support. ”
Eric R Bitkeu Bongni (Buyer)
“Bill was a pleasure to work with. We viewed several properties and he was very patient and was able to address any questions or concerns that I had. He kept in contact with me through text and emails and quickly responded when I reached out to him. I am a first time home buyer - at times I was a little stressed out and Bill was right there to keep me from going over the edge. I certainly learned a lot and over all it was a good experience. ”
Alison Burden, Germantown (Buyer)
