GMAC will file an eviction against the previous owners to vacate the property, this will take at least 60 days, 90 days for tenants, so depending on when the the trustee sale was then they have time. Did anyone show up yet to offer cash for keys? That is the first step from the bank’s playbook. If you don’t want to play then they proceed to evict but even then the 5 day notice is posted before the sheriff shows up. Just did one today where we got the asset after the sale in February and the tenants stayed until yesterday and we took possession this morning.
