What makes the loan pay off sooner?
Direct-deposit of your income into this mortgage. It has an immediate and dramatic impact on your principal balance. With this loan, interest is based on your daily balance, so when your paycheck hits, you start saving interest compared to a traditional loan. This leaves more of your income available for principal, accelerating the buildup of equity with no change to your spending habits. Naturally, the more positive cash flow you have, the faster your loan paydown will accelerate.
