I am in the market for a house in the San Francisco South Bay or Peninsula, and the few web sites I've tried are good but not great (realtor.com, trulia.com, redfin.com, windermere.com, mlslistings.com). None of them have 100% of the listings, including For Sale By Owner or REO listings, or are too hard to search (no visualization on a global map of the area). It would be great if there was a truly good site that aggregates all the possible listings, with a good map view, a detailled search filter, and the most up-to-date listings. Can anyone provide recommendations? Thanks
