Which of the following is NOT a type of mortgage mentioned?

The choice identified as a hybrid mortgage is considered the correct answer in this context because it is not commonly recognized as a specific type of mortgage in traditional real estate financing.

In contrast, a purchase money mortgage is a well-established term that refers to a loan obtained to purchase real estate, where the seller provides financing to the buyer as part of the purchase transaction. Similarly, a reverse mortgage is a type of loan available to seniors that allows them to convert part of the equity in their home into cash, with the loan being repaid only when they sell the home or pass away. A blanket mortgage serves a unique purpose, as it covers multiple properties under a single loan agreement; this is especially useful for developers who want to finance several properties at once.

In summary, identifying that a hybrid mortgage does not fit into the standard categories commonly used in property financing highlights its absence from recognized mortgage types.
