There's places all over where land, and sometimes land with buildings gets very inexpensive because there's not much demand.

Here's a listing for a parcel for $9000, that's been listed for over a year[1]. Denver seems like a nicer place than Detroit, IMHO, but it's possible for there to be more supply than demand.

I suspect at 5% annual growth in units, you would be able to reach the point where there's not enough demand for builders to recover costs. It might take a few years, depending on just how much unmet demand there is.
