In San Francisco, the walk score is an essential part to a homes value. So many people want the convenience of restaurants, transportation, shopping and in your case grocery stores. The addition of Whole Foods, a major successful market in that area on Ocean Blvd. will most likely bring in more people who would otherwise look in somewhere else. The addition will act as an anchor for the community to gather, a place to get GREAT food and support strong commerce. Let me know if I can give you a home evaluation or find some comps in the area.
