Yes, check the recorder’s office online for a recission. If it’s not there, then the foreclosing bank is either working out a trial mod with the trustor or, like another poster said, there has been a substitution of trustee which delayed the trustee’s sale and the new substitution has not been filed yet. I would call the last known trustee and give them the property info and ask if they have a new sale date pending and/or what the status of the property is.
It’s not uncommon for a TS to be postponed several times, even at the last minute.
