Definition: Mortgage 100, also known as a "20% down payment" mortgage, refers to a type of loan that requires the borrower to make a small deposit (often from less than 20%) out of pocket before receiving any funds. The reason for this is so that lenders can assess the ability of the borrower to repay the loan and the risk associated with the loan. Mortgages are typically used as an alternative to traditional home loans, which often come with higher interest rates and fees due to the security of the property. However, borrowers who have a low credit score or can prove they cannot afford the full amount of the mortgage may be eligible for mortgages that require just 10% down payment. The term "mortgage 100" is commonly used in financial news reports to emphasize the importance of getting a low down payment on a home loan, as it can save borrowers hundreds or thousands of dollars over time.
