Which of the following is not a type of loan?

The answer identifies that "Commercial loan" is not a type of loan in the context typically understood for residential real estate financing. This reflects a misunderstanding because commercial loans are indeed a type of loan specifically designed for purchasing, refinancing, or developing commercial properties, such as office buildings, retail spaces, or industrial properties.

On the other hand, an FHA loan is a government-backed mortgage designed to assist buyers with smaller down payments and lower credit scores, making home ownership more accessible. A prime loan refers to a loan offered to borrowers with good credit, typically featuring lower interest rates due to the reduced risk to the lender. A conventional loan represents a standard mortgage not backed by any government entity, often characterized by its fixed or adjustable interest rates.

Understanding these categories of loans is essential in real estate because different situations and property types will necessitate leveraging the appropriate type of financing to achieve homeownership or investment goals.
