Zoning can allow a mobile home on a parcel and a recorded deed restriction can still forbid it. The restriction binds the land, not the seller, and a listing that says unrestricted is a description, not a document. The county's paperwork calls the same house a manufactured home, so read the covenant for the words it actually uses.
Short answer: Before relying on a listing, read the deed restrictions, covenants, subdivision rules, HOA documents, the recorded plat, and any private road or shared access agreement. Restrictions on manufactured homes, mobile homes, home age, size, foundation, and appearance are common in recorded documents even where zoning is permissive.
