That works only if the buyer wants to upgrade a house they already own.

If the buyer does not own a house already, then it's a scam.

Considering most/all new homeowners will be stuck with lower-tier smalls, I don't think finding a buyer would be terribly difficult.

This is very much a market crafted by Square's own hands.
