Smith. Bill has been one of the top producers in Marin residential real estate for decades, with 76% of his total sales in Tiburon and Belvedere. He has been very active in community service and local government for over 40 years, as well.  Bill’s distinctions include:

Bill’s success in residential real estate rests on a strong foundation in finance, land use, and planning. He earned his degree in Business Administration at the University of Texas, and began his career as a C.P.A. with Price Waterhouse. He was involved in many aspects of commercial real estate sales and development before focusing exclusively on residential sales.

Bill is a dedicated family man who appreciates all that the area has to offer family with regard to excellent schools, activities, facilities, and neighborhoods. In his free time, Bill enjoys sailing on the San Francisco Bay, skiing in Tahoe, and savoring nearby San Francisco’s renowned culture and attractions.

Bill Smith Real Estate Testimonials



Highly Professional and Well Respected

Bill and Ann are known for their integrity, and they have a wealth of knowledge about the market, excellent relationships within their profession and the community, and they are incredibly nice.  Excellent experience. They showed great patience as we viewed different types of properties and developed a very good understanding of our needs. There is no one else I would recommend as highly as this team. 


Highly Recommend

Bill and Ann were excellent from our initial drive around to closing. We were first time home buyers purchasing a house in the very competitive Marin market. Their responsiveness, connections, and market knowledge ultimately helped us find our dream starter home. They were there for us throughout the process, even after multiple losses, they helped us remain patient and find the right house. I would highly recommend them. 


Very Knowledgeable

We bought a condominium with Bill and Ann, who previewed properties for us and sent exceptional detailed evaluations highlighting relevant items. They cared about our individual preferences and did a great job matching those to properties - very knowledgeable! They are fun and a pleasure to work with!


Respected by Peers

Bill is a pro. He has long established relationships in the real estate community, and the respect of his peers for good reason, Bill is a tough negotiator, he's thoughtful, and has excellent instincts. I have worked with him for several years now and refer him to friends whenever asked for an agent referral. Simply the best. 


Well Connected

When I was looking into moving to the Belvedere/Tiburon area, Bill came highly recommended to me as THE realtor to use to help find my future home. I found he more than lived up to this recommendation. Bill worked hard on my behalf. He was accessible and incredibly easy to work with. He was clearly well connected within this community and within his profession. As a result, he was able to gain access to several homes before they were listed, including the one I ultimately purchased. I found he provided solid advice and put great effort into helping me work through numerous challenges we faced in getting my home closed. I would happily and strongly recommend Bill to anyone looking to hire a realtor.


Hard Working

Bill knew the market inside and out. He was hard working on our behalf, negotiated a good deal, and was on top of all the details necessary to close. I highly recommend Bill.



Actually Bill was our selling agent on two homes and buying agent for 1 home. So 3 transactions in total. Bill seems to know - literally - everyone in the area, and has been in the Southern Marin Real Estate market for many years, and in the Finance sector before that. I believe this combination of Real Estate and business experience serve his clients well. Throughout each part of the engagement/transaction, Bill was a knowledgeable, punctual, and reliable professional. We would use his services again, and would (and have) recommended him to others.


Leader in the Industry

Bill helped us sell our home, and buy a new home. Bill is extremely knowledgeable and caring. Bill is a leader in his industry, and anyone would benefit from his knowledge and experience. When it comes to a realtor, there is only one choice:  Bill Smith!
