Answer: A. Big down payment, a longer term loan, and a low interest rate
To keep a monthly mortgage payment as low as possible it is important to swing a larger down payment, opting for long term, and having a low interest rate. You can keep your payment low by swinging for larger down payment; going for a 10% down payment instead of a 3.5% down payment in the FHA will knock the payment down simply by borrowing more money. If you desire a low payment, it is advisable to go for the longest term possible so payment can be stretched by more years.
