This is how a lease option should work: After securing the go-ahead from a mortgage broker and before moving in, your potential buyer will give you a healthy, nonrefundable deposit to go toward the down payment of the house -- typically, 3 to 5 percent of the purchase price.
The amount of interest that accrues on your loan is determined by a simple daily interest calculation: Your current principal balance Ã The number of days since your last payment Ã Interest rate factor = interest rate Ã· 365.25 (number of days in a year) = Your daily interest rate.
2. Divide the interest rate by 12 to determine what your interest rate for the month is. Multiply this by the amount of the principal to get the amount you're paying in interest in the first month.
