Your best bet is to contact a Realtor who can perform a search of the MLS for you. Of course, you said "no restrictions" - do you have something specific in mind. This would help define the search for an agent. There are often some restrictions, but depending on what you're hoping is allowed, this can help give you some more options that you might not have seen before (as well, some agents just put "of record" in their listings, making it harder to know exactly what the restrictions are - that's when I call in the title company for clients, they can always give you good solid info on deed restrictions).
Are you thinking of building? Or a manufactured home? Horses? These are all common questions I hear when people mention restrictions, so I figured I'd ask them of you.
