A general warranty deed (what you refer to as a warranty deed) contains certain warranties that the title is good and marketable.
A special warranty deed USUALLY means that the deed contains the same warranties but that the seller is only making the warranty with respect to anything that occurred while they owned the property.
It is a common form of deed particularly for lender owned properties where they have no idea about previous title issues. If you buy title insurance, I would consider it to be a “safe” conveyance.
