Which of the following is not a type of real estate loan?

The answer is indeed convertible loan. In the context of real estate financing, the correct terminology and concepts are crucial for understanding the various types of loans available.

A package loan combines a mortgage for real estate with financing for personal property, often used for purchasing furnished properties. An open-end loan allows for additional borrowing against the same loan, making it flexible for borrowers who might need to access more funds later without taking out a new loan. A fixed-rate mortgage is one of the most common types of loans where the interest rate remains the same for the entire term of the loan, providing stability in monthly payments.

Conversely, a convertible loan, while it may imply a loan that can be converted into another form (for example, a convertible bond in corporate financing), does not specifically relate to standard types of real estate loans recognized in typical real estate transactions. The terminology usually encountered in real estate financing does not categorize convertible loan as a distinct type of loan for real estate investments.
