Definition: The term "mortgage yield" refers to the percentage of returns that a borrower receives from the sale or purchase of mortgages (also known as loans) over a given period of time. The mortgage yield is calculated by taking the difference between the loan amount (the amount borrowed at the start) and the market value of the property being used to calculate the interest paid on the loan. This can be expressed in percentage terms, such as 0% or 100%, which represent no returns are expected from the sale. The higher the mortgage yield, the more interest a borrower receives when they sell their home, and conversely, the lower the mortgage yield is, the less interest a borrower will receive when they purchase it. In other words, a higher mortgage yield indicates that the investor has received a higher percentage of the property's value as interest. The mortgage yield calculation formula can be expressed in multiple ways depending on the market conditions and the type of mortgage being purchased or sold. For example, it could be calculated using a simple rate or a compounding rate (which calculates interest on the original loan amount each month), or it could be adjusted for different types of mortgages such as adjustable-rate or fixed-rate loans.
