Buy your first property for $50K. When it is worth $80K, trade up to a better property. When that property is $110K, trade up for another property. By the time you die, you will have real estate worth $2M for which you only paid $50K. If you utilize the like-kind exchange rules when transferring between each property, then you can pass away holding the last property and the nearly $2M of gain could potentially vanish upon your death. If you would rather enjoy that appreciation for your own personal use while you are still alive, then you can borrow against the $2M property in retirement and enjoy the use of the borrowed funds without selling the property and being forced to recognize a gain…and, to top it off, the gain could potentially still disappear upon your death.
