Yes, 3X Location is the theme for real estate sales these days. I never talked about that part of the business with grandpa. But keep in mind, the economy was in shambles after the CRASH in 29.
I don't know how well you did in R.E. it but my mom grew up attending private schools and they lived accross the street from Hubert Humphrey for a while. Grandpa once lamented that he couldn't buy a new Packhard for a few years. Had to make do with a Ford.
