Which of the following is NOT a type of deed that can convey real property rights?

A general assignment is not a type of deed used to convey real property rights. Instead, it is a legal instrument typically used to transfer contractual rights and obligations, such as the rights to receive payments or enforce contracts, but not the ownership of real estate itself.

On the other hand, the warranty deed, grant deed, and quit claim deed are all recognized forms of deeds specifically designed to transfer ownership of real property. A warranty deed provides the highest level of protection to the buyer, as it guarantees that the seller holds clear title to the property and has the right to sell it. A grant deed also transfers ownership but with fewer guarantees than a warranty deed. A quit claim deed is used to transfer any interest the grantor may have in the property, without making any warranties about the title.

Thus, while the first three options are tools used in real estate transactions to establish ownership and rights, the general assignment does not pertain to real property conveyance and is the correct response to the question.
