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

The correct answer identifies "Rent-to-own mortgage" as the option that is typically not considered a type of mortgage.

A conventional mortgage is a standard loan that is not backed by the government, and it usually adheres to certain criteria set by lenders and investors. Subprime mortgages are those offered to borrowers with lower credit ratings, often characterized by higher interest rates due to the increased risk to lenders. A fixed-rate mortgage is a common type of loan where the interest rate remains the same throughout the duration of the loan, providing predictability in payment amounts.

In contrast, a rent-to-own arrangement is not a true mortgage. Instead, it is a hybrid arrangement where a tenant rents a property with the option to purchase it later. While it can lead to homeownership, it doesn’t involve a mortgage until the purchase occurs. Thus, it doesn't fit into the category of traditional mortgage types recognized in real estate financing.
