The point that many are trying to make is that there is (or should be if lenders weren’t so whacked) a fixed amount that the average family can pay per month. Currently, you can get a low interest rate but high loan amount. It is much better to have a higher interest rate but smaller loan. In both cases, your monthly payment is the same at the outset. With the second situation, however, you MIGHT get the option to refinance into lower payments. You will also greatly increase your chances to make money in appreciation.
