NFT is issued determining ownership to a property. Property sells, another NFT is issued, tied to the original one to maintain a chain of ownership. Issuance of a second NFT for a sale to a new owner would depend on authorization by the previous NFT holder. Lienholder information could also be stored, and linked to a mortgage NFT with payment history.
The "NF" part of that stands for "non-fungible." As in, once created, cannot be changed.
