Which of the following types of mortgage clauses is intended to prohibit the assumption of the mortgage?

Subordination clauses relate to the hierarchy of claims against a property. They determine which lender has priority in the event of default but do not address whether a mortgage can be assumed by another party. Therefore, subordination does not prohibit assumption; rather, it deals with the order of claims and does not influence the terms of assumption.

Acceleration clauses enable the lender to demand repayment of the entire loan amount if certain conditions are met, such as missed payments. While this clause can lead to foreclosure if the borrower defaults, it does not specifically prohibit the assumption of the mortgage. Thus, acceleration clauses focus on the borrower's performance rather than ownership transfer.

Amortization refers to the process of gradually repaying a loan through scheduled payments over time. This term involves the financial mechanics of the loan but does not address the transfer of the mortgage or the issue of assumption. Consequently, amortization has no bearing on whether a mortgage can be assumed by another party.
