Sarah Newmarker

We would work with Sarah again with zero hesitation. She is incredibly organized, and process driven but flexible for the unique conditions involved in any real estate transaction. Sarah helped us sell our Marin home and guided us through the process in a clear, organized fashion resulting in multiple offers and a sale over asking. We have referred Sarah to multiple friends purchasing houses in Marin and they all had 5 Star experiences working with her. Sarah is the best!

Sarah is a fantastic agent and we highly recommend her!! Thanks to Sarah, our home sold for over-ask the next day in 5 days with a  2-week close. We will absolutely will be working with Sarah again!

Sarah did an amazing job finding the right buyer for my mom's home. I've worked with many real estate brokers over the years but no one as skilled and professional as Sarah!

Sarah is the best! She helped us to both buy and sell our home in Marin. We could not be more pleased with her results. In each instance, Sarah went over and above her call of duty to make sure we felt comfortable through the process. Her knowledge, professionalism and attention to detail differentiate Sarah from the average real estate broker. She is a trusted advisor and has a client-first mentality. Definitely someone I would highly recommend to anyone seeking to buy or sell a home!

- Yet & Christine H, San Rafael

Sarah made our dream possible to live in downtown Mill Valley with her exceptional skills, negotiations and hard work on all levels. We knew it would be very difficult to get into the neighborhood in our price range. She was able to make it happen. Thanks Sarah, you are our rock-star:-)
