With at least 20% down it is still possible to approach 50% of income as a back end ratio which means all of your monthly minimum payments on a credit report + houisng expense. If you have no credit card debt/student loans/car payments etc, you can approach 50% of income with just your housing expense.
It’s the 2nd biggest Ponzi scheme condoned by the govt. The largest Ponzi scheme is 401K’s & other retirement accounts. What will save America ???
