This particular property looks to have delayed the public sale until 7/23, with Jim’s public records service picking it the reverting to First Federal on 7/30. The 4/3 date is just the date published on the Notice of Trustee Sale, which is legally the earliest it could happen.
It is not uncommon at all for a trustee sale to delay many times. Lenders try to meet the timeline minimums on filings for legal reasons, but very rarely get properties through the process that quickly.
Sometimes it’s a week at a time, sometimes a month or more, as lenders try to work out all the needed assignments and legal documentation, deal with bankruptcies, and, in the current climate, “hope” that somehow the home will sell or the borrower will cure.
