Eventually those bank owned homes will sell and back in use by someone who won’t be renting. Ease the rental market strain.
Seems there is some correlation also between the builders cutting back on future building, causing concern of decrease of homes. However, with the continued tightening of credit standards, that decreases the buyers.
I’m personally amused by the incentives of builders, upgrades, etc. Really, the only thing that will sell is drastic reduction in price. DR Horton seems to have figured that out. Maybe some others will follow suit.
