The term "release clause" refers to a specific provision within a blanket mortgage that allows for the release of individual properties from the mortgage obligation as certain conditions are met, typically upon the repayment of a portion of the loan secured by those properties. This is particularly important for developers or real estate investors who may want to sell off individual properties while maintaining the overall mortgage on the remaining properties. By including a release clause, borrowers can ensure that as they pay down their loan or sell properties, those specific properties can be taken out of the mortgage, freeing their titles and simplifying individual transactions.

The other terms listed do not apply to this context: a cancellation clause pertains to terminating the agreement altogether, a subordination clause involves changing the priority of liens, and a subrogation clause is related to replacing one party with another in terms of legal rights.
