You can use any building, that contains a bedroom, as a home - although if it also serves a business function, you would not earn any rent from it. The following standard buildings all contain at least one bedroom and can be used as a home. Some have more than one bedroom, and that information is listed in parentheses after the entry. Some of the larger buildings also include lodgings (or bunks) that can be used for servants or a garrison.

Academy, Alchemist, Bardic College, Caster’s Tower, Castle (x3), Cathedral, Exotic Artisan, Farm, Fort, Garrison (x2), Herbalist, House, Magical Academy, Mansion (x4), Military Academy, Noble Villa (x4), Orphanage, Palace (x6), Temple, Tree House (x2) & Witch Hut.

You can find costs for each building at Building Lists
And details in the Paizo buildings List

You may also create custom homes using thePaizo Room Lists. However, the home must be sensible and acceptance is always at the discretion of your GM.
