We are seasoned real estate investors that highly recommend Brian's real estate services. Brian was instrumental in the recent successful sale of our duplex in West Seattle. From the onset he provided the very specific real estate market details which allowed us to make informed decisions on strategy, price, and timing of our sale. Ultimately, we were able to sell the property off market to a private investor introduced through Brian. The escrow was even easier as Brian had prequalified the buyer and streamlined the deal closing. Throughout the entire process we felt Brian had our best interest in mind, so because of that we plan to utilize Brian's real estate services for ALL our future transactions.

I had the pleasure of working with Brian on the purchase of our new home and the sale of our old home. I must say that my experience was nothing short of exceptional. Throughout the process, his professionalism, responsiveness, and attention to detail were commendable. He guided us through every step of the buying/selling process, ensuring smooth and stress-free transactions. His negotiation skills were impressive, and we know confidently that he always had our best interests at heart. I couldn't have asked for a better real estate agent, and I highly recommend Brian's services to anyone in need of a trustworthy and highly competent professional in the real estate industry.

Brian Side has been an extremely great partner in selling our house. He has been the most responsive, knowledgeable, and reliable realtor with whom we've ever worked. Brian's ability to get the job done while maintaining a relaxed and friendly demeanor is exceptional. I personally want to thank Brian for helping me find a rental all while doing the work with our house to sell. He did not have to go this extra mile, but he did so with professionalism and understanding. I highly recommend Brian Side as your realtor.

We just finalized purchasing a property with Brian and I would highly recommend him for others looking to do the same. He is knowledgeable, skilled, and a great communicator….all traits that made the process of buying a home less stressful than what it often times can be. We will certainly have Brian represent us again for any future real estate transactions!

I can’t say enough good things about our experience working with Brian Side! When we decided to purchase our first home, we were quickly overwhelmed with the process. Luckily, we reached out to Brian who was incredibly kind, patient, and insightful when it came to both the home-buying process and the specifics of buying a home in the Seattle area. He listened to the neighborhoods we were interested in and the features we sought in a house and was sure to send us listings that were excellent fits as well as those that we may not have originally considered. He was quick to give lots of details on places to see and things to do when we decided to explore a neighborhood that was new to us. And while we worried that we’d be wasting his time touring a home that we weren’t completely sold on, he assured us that it wasn’t a problem and we ended up buying that home! Brian helped us handle negotiations with the builder, gave honest feedback about the home, made himself available for endless questions and inspections and helped recommend other stellar people to help us with the rest of the process. Throughout the entire time that we were in escrow, Brian kept us in the loop and made sure that we were informed and excited about this big step. There were so many moving pieces, but Brian made the process as easy as possible and we’re so grateful. If you’re looking for a home in the Seattle-area, we highly recommend working with Brian Side!
