By "when" I was talking about what year, not how old you were. Doing all this in the 70's was simple easy. Doing it in 2015 it's almost impossible.

Actually, doing this in the 70's was not so easy. I lived through the Carter years. Interest rates climbed to 24%. My father, a holocaust survivor and self made man, was a realtor at the time. The Carter years forced him out of business.
