Hear From Our Clients

William Bolls’ impeccable guidance, incomparable service and impressive negotiating make each client’s property purchase or sale a rewarding, satisfying experience. His fine work and reputation as a stellar real estate “consultant” have earned him not only prominent industry recognition, but a long, loyal following of repeat and referral clients as well.

“I woke up the day after my last closing with overwhelming gratitude to have had an agent like William. We have worked together on both sides of the process — as both buyer and seller — and if you are looking for a resolute professional with a knack for excellence, clarity and efficiency along every step of the way, William is your man.”


“We highly recommend William. His experience with the New York City real estate market was clearly evident throughout the sale of our apartment, including setting the right sale price, finding the buyer quickly, and making the entire process seamless. William surpassed our expectations by independently staging our apartment to show its full potential.”


“William Bolls is the best!! My husband and I worked with him on our recent purchase of a co-op in Manhattan. He’s smart, super knowledgeable and gives great, thoughtful guidance. We strongly recommend William to everyone!”


“For the absolute best broker to guide your home finding and buying experience I recommend William. He is the consummate professional who can offer and match you with the home you’ve yearned for.”


“The selling process is not an easy one, but William’s knowledge & expertise along with his genuine helping personality saw us through. His expertise was noticeable as soon as he walked into our apartment. Days after our initial open house, William happily gave us news that we had received two offers (of which we gladly accepted one). I can say without a doubt that I fully recommend William.”


“We met William on the Upper West Side but he found us the perfect apartment in Park Slope, which is where we really wanted to be. William not only was able to direct us to the properties that we should see, but as soon as we found “THE ONE” he helped us in every way — from our first bid to closing day. He is very good at what he does and he does it with ease and intelligence.”


I can’t imagine purchasing a property in New York City without William. As an out-of-town buyer, we faced additional challenges when we decided to buy an apartment in the city. As cliched as it sounds, William truly made us feel like his only clients. It’s not a simple process and we required a decent amount of hand-holding. He was there for us every step of the way, even anticipating a lot of our concerns. One of the most valuable characteristics of a good agent is responsiveness. Any time we contacted William–and it was often–he responded quickly and completely. William will definitely be our agent on future transactions.

– TIM M.

William and his team were wonderful to work with. They were very responsive to my questions and concerns, and had extensive knowledge and expertise of the market. From our first meeting, I knew I would be in good hands. They walked me through the process of selling my apartment with ease, which took much stress out of the process, and were proactive in marketing my apartment. I would 100% recommend William and his team to anyone looking to sell their property.


William first helped us in 2013 as first time purchasers of a COOP on the Upper West Side. Having come off a less then favorable first attempt with a different broker we were skeptical and thought that maybe purchasing property was just a horrible process. We couldn’t have been more wrong. William and his team made the whole process so relaxing and pleasant. When we decided to sell in 2018 there was never a question as to who we would call. All told William and his team have helped us purchase 2 properties now and sell 1, if and when we ever decide to move again we will most definitely seek Williams guidance and assistance!
