Contra Costa California Real Estate

Your Source for Discovery Bay and Contra Costa Real Estate

Mary Carpenter, Coldwell Banker Top 100 Northern California

Contra Costa County is a great place to live and raise your family.  I have lived here for over 10 years in the Brentwood Discovery Bay area. This area has it all!  Wide open spaces, farm fresh vegetables, and fruits, we grow our own here, small town feeling with a charming downtown area.  If you like water, boating, fishing, water skiing, wakeboarding or just cruising around you will love it here.  Lots of recreational activities! Personally, I love the hour plus drive up to Napa Valley and San Francisco, and only a 3-hour drive to Carmel, Yosemite, and Tahoe.

"Mary was our real estate agent when we bought our first home earlier this year. She is very knowledgeable and guided us through the whole process with ease (we used a VA loan). We love our home and definitely recommend Mary for your real estate needs!"
- Erik & Heather Rivera

"Mary is a pleasure to work with! I highly recommend Mary to all of my closest friends & family! We were so comfortable and she always paid attention to our needs. I will be using Mary's services again real soon."
-Rob & Jen Vargas

"Mary helped us purchase a home in October in Brentwood. I was afraid of what a headache the process would be like, however Mary made it as easy as possible. She listened to our needs and concerns, and made the process smooth!"
-Amy Berard

"Mary worked tirelessly to help us purchase just the right house. Our criteria included solar and a rancher-style layout. Using her extensive knowledge of local builders, she successfully directed us to a builder with a rancher model that included solar electric, heating, and hot water. She monitored the building from start to finish, always keeping us in the loop. Whenever anyone asks us about a great Realtor, we always give them Mary's name."
-Cheryl Salamone
