The only market for real pianos these days is with serious professionals, concert venues, and people who use them as furniture.
I also wouldn't say that a real piano is only for a serious pro. Real pianos are a different instrument from keyboards; I wanted one within two weeks of starting piano lessons. But that brings us to the other half of the equation: New pianos are relatively inexpensive, because manufacturing is increasingly efficient. It's more cost-effective to buy new than to take a chance on rehabilitating a piano from 1962.
EDIT: Incidentally, when I say "relatively inexpensive", I mean "for a piano". There's a very real temptation to stick with electronic keyboards. The temptation is measured in kilodollars.
I used to be a sceptic, but playing the latest digitals which acoustically model the soundboard, strings and action of a piano, the experience is very impressive. It genuinely does feel like playing the real thing, even if the sound comes through speakers. If I come to buy my own piano, I'd go digital.
Lots of info at that subreddit FAQ. Also this, about how Yamaha makes lots of models with Graded Hammer Action

That could be because I learned on a real piano, I acquired sloppy habits that a real piano forgives. Perhaps people learning on a digital would learn different sloppy habits that only a digital would forgive.
