Default just means they’re in preforeclosure… Default means a notice of default was issued. Next step (at least 60 days later) would be a NOT (notice of trustee sale)… then, depending on how they work the system… they can kick the can down the road for a long time.
But – since the house is vacant – they might just let it go back to the bank.
I have my speculation about it, see your PM for details. But it’s strictly speculation.
