Ideal for a young healthy couple with a man that loves Home Depot and a wife that is good with people and bookkeeping.You don't have to wait to buy the real properties. You can buy the property now, and pay them off with money worth less and less every day. Granted that you'll be paying interest on the money, but if you have tenants, they pay it off for you, and it becomes easier and easier to pay the mortgage as their rent climbs. Then in a financial collapse, pay off the property for the value of a loaf of bread.
