The foreclosures are posted on https://www.tnpublicnotice.com/, but it is time consuming to scrub through all of the foreclosure postings for the address auction date, and then begin my own diligence (zillow, tax records, etc.).

You may need to open up the wall completely and replace the wood behind it, but that is unlikely to be the caseThe key is to remove the substrate entirely; I would NOT try to clean it up by scrubbing off the mold or painting it or covering it...

I recently started a new role where I am scrubbing in for surgical valve replacement.
