A mortgage may be secured by which of the following?

A mortgage can be secured by a variety of interests related to property. The correct answer indicates that a mortgage may involve the whole property, an undivided interest, or a right in-rem.

Securing a mortgage with the entire property is often the most straightforward method where the lender holds a claim against the entire asset. However, the concept of securing a mortgage by an undivided interest means that the mortgage can also be applied to a portion or a shared interest in the property, which is crucial in cases where multiple parties may own the property or participate in a joint investment.

The term "right in-rem" refers to a right in regard to a particular thing, typically in terms of real property law where the mortgage creates a claim against the specific property regardless of the ownership specifics. This flexibility allows lenders to secure their interests even in more complex ownership situations, such as co-owned properties or various forms of joint ventures.

Choosing the option that states the various forms of property interest that can secure a mortgage reflects a comprehensive understanding of real estate financing and aligns with the practices governed by regulations and laws in real estate transactions.
