Regarding condos (condominiums) they are relatively new here (Houston) depending on what you mean by relatively.
Back when I was in high school I took a bus tour on a trip to New York City and I remember the tour guide noting that people actually owned (as opposed to rented) the apartments they were living in in some of the more exclusive high rises.
Own an apartment! Never heard of such a thing! (This was late 70s.)
Some time in the mid 80s, the condo craze here in Houston went viral. Suddenly it was The Thing To Do to own an apartment (which was now called a condo or sometimes, a townhouse) instead of renting it. A bunch of apartment complexes (most of which were having trouble getting renters) suddenly turned into condos and were selling off each individual residence. And people bought! It was crazy as many of these were places that you wouldn't want to rent but the idea of owning it! well, that was a completely different prospect.
In the end, so many of those ended up getting foreclosed on and many got turned back into apartments. However, the ultimate result was that condos were here to stay. There were/are plenty of nice ones and I know people who live in some.
So, 70s, never heard of it. 80s, all the rage. 90s & beyond, common, representing a certain percentage of available housing along with free standing houses, apartments, duplexes, etc.
