I agree with Cecile. As real estate brokers, we have access through our Marin Multiple Listing Service with all the closed sales in every city. It might be beneficial for you to obtain a full CMA (comparative market analysis) for San Anselmo so you can get an overview of all of the closed sales in San Anselmo. This report gives a consumer days on the market that the property has had, any price reductions, percent of the list price to the sales price, and you can then look at the overall picture of what the market is like in San Anselmo.
Also, San Anselmo has a few different neighborhoods, and as agents, we can break the statistics down to your neighborhood, whether it's Sleepy Hollow, downtown, Yolando Park, Hawthorne Hills, Morninside, etc.
Hope this helps, Madeline Schaider
