Earlier quoted context omitted.
If they're condos, you can own it, at least as much as you can own half a duplex. If they're rental units, that's also ok, more supply brings down rents and lower rent causes more landlords to sell. Extra supply does add downward pressure on prices one way or another. I don't see where the "value destroyer" is.
> more supply brings down rents People say that on here all the time, but I have never seen that happen. Do you have an example where increased housing supply lowered prices aside from a natural or market disaster? Maybe, Detroit where people simply abandoned their homes with no intent to sell.
This is not quite the same thing as an immediate increase in supply, but instead a large drop in demand. The net result is the exact same thing: a large increase in the vacancy rate, which resulted in a rapid and dramatic decrease in median rents.
