Thge foreclosure seems to be just beginning.
Your written answer to file with the court is the best way to stay in the loop. File with the court a letter to the clerk referencing the exact case name and case number stating that you have a lease through June and need XXX days to vacate. Then you will be advised by the Court later on when the foreclosure is over and when you need to leave. Foreclosures are running so slow now, it may not be over by the time your lease is up. If you actually get thrown out before 6/31 you owe no more on that lease, it seems.
Use the prop mgr to get a new lease on a new prop now is probably best.
try going to a legal aid office to review the status of the court file and give specific advice.
