Which of the following is a document that can be classified as a mortgage?

A trust deed can be classified as a mortgage because it serves a similar purpose in securing a loan for property purchase. In real estate transactions, a mortgage is a legal agreement where the borrower conveys an interest in real property to secure a loan, with the understanding that the lender can take possession of the property if the borrower fails to meet the loan obligations.

A trust deed, sometimes used interchangeably with a mortgage in some jurisdictions, involves three parties: the borrower (trustor), the lender (beneficiary), and a third party (trustee) who holds the legal title of the property as security for the loan. This arrangement allows the lender to initiate foreclosure on the property if the borrower defaults, similar to the rights granted by a conventional mortgage.

Other options, like a loan agreement and a promissory note, while integral to the borrowing process, do not establish a direct claim or lien on the property itself. Instead, they outline the terms and promise of repayment without providing the necessary legal claim over the property. A lease agreement, on the other hand, involves rental rights and does not pertain to securing a loan, thus distinctly differing from mortgage-related documents.
