Which combination of factors would result in the lowest monthly mortgage payment? Having a larger downpayment, a lower interest rate and longer loan term agreements are all ways to have a lower monthly mortgage. When you put a larger down payment on your home, the amount you are borrowing is less which helps bring the payment down. If the interest rate is lower, your payment will also be less because you do not have a significant amount being added to the principal.
