Quote from MR.NBBO:
This type of scenario is probably the easiest way to tell a RE "bubble" in local areas. If it wont positive cash flow, or the replacement cost is much less than what it currently sells for.....then you've got a good bit of downside risk.
Properties above 10x cash flow are really banking on the appreciation potential, ie. speculation.
My rentals have appreciated at about 8% avg./yr and trade at 6.5-8.00 cash flow currently (they still make sense). Other area rentals in TX sell in the 7-8x cash flow range. We don't appreciate like CA.....but we don't tank like 'em either.
