We worked with Helen to sell a house and then to buy another one. Helen has been great taking us through both processes. She is very knowledgable about local housing market and provided us with a lot of suggestions on area, timing and pricing during our search. When we decided to make an offer, she  is very professional and helped us research the market and the area to make sure our offer is competitive but also within our expectations. We were able to get the house within our budget even when competing with multiple offers. We would highly recommend Helen to anyone that's looking to sell or buy a house in the Bay area. She and Rachel makes a perfect pair.
