Literally a couple decades like 20 years? I just don't think that could be true, at least not where I live.
Looking at the listings in a broad radius around me, there is still a lot of housing built in the 1960s and 1970s being bought and sold quite regularly, and some stuff even older. A house built in 2004 ("a couple decades") would absolutely not be worth the cost to rebuild.
