"William Bolls is THE broker you want when buying and selling in Manhattan"

"William Bolls is THE broker you want when buying and selling in Manhattan. He is a wealth of knowledge and really takes the time to make sure you understand the process and are getting exactly what you want. I can't recommend him highly enough, and send him to anyone I know looking to buy and sell, especially the UWS."

"“I can't imagine purchasing a property in New York City without William"

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.

"The market was tough, but William stuck with it and brought it home"

I worked with William over a lengthy period, trying to sell a lobby level doctor's office in a residential co-op building on the upper west side. The market was tough, but William stuck with it and brought it home. He showed patience and was always straightforward, honest and friendly throughout the process. Definitely 5 star.
