Looking to buy a mobile home in California Bay Area? 
  Buying a mobile home is different from buying a home or condo.  Most Bay Area parks owners require a minimum income of  3 x the $400-700 space rent plus 3 x the any loan payment to qualify to live in their park.  If you planning to finance a mobile home that is not new or attached to a permanent foundation regular banks and mortgage brokers can not help you because banks treat them as personal property like a car.  The average interest rates on mobile and modular homes is between 9-11.5%. The single wide mobiles epically the older ones are even harder to get loans on. (List of lenders are in the left margin)
  May Communities have rent control limiting space rent increases.  Building Codes are regulated by the HUD and not by local government thus quite different from your standard house.
  A modular or manufactured homes have been built so that they are often difficult to tell them from a stick built home.  Finding a space in a local mobile home park takes years on a waiting list and most often folks simply buy an old mobile and pull it out so they can put in your new modular home.  When buying this type of homes the parks space rent can very widely with in the same park and some of the newer home can be on the property taxes roles as well.  If you are placing a new Manufactured home on a lot of land it must be attached to a permanent foundation to get ordinary bank financing.
