"Title" means ownership. But ownership can be "encumbered," for example, by a tenant with a lease, which is an "interest," something which is less than full ownership but which is legally enforceable and usually recorded if it has to do with real estate. "Interests" include those established in probated wills and in trusts, those established in mortgages and judgment liens, and those established in recorded easements. "Rights" is a hodge-podge term that applies to everything else. It can include contractor liens, homestead interests, prescriptive easements (common-law easements), the rights of neighbors under restrictive covenants, and many other things. (StackExchange)
