My renters have paid for all 7 of my houses, plus my personnal home, no house payments now on any of them.
Got to live & pay somewhere, may as well OWN it. The investment part is not how much you make on it, it is a matter of living rent free, getting it paid for and coasting into retirement and old age,and leaving something to your children. That is the investment, but no trying to fix stupid, just take advantage of it. Invest in rentals.
