As far as encapsulation, there aren't any specific requirements in MN code.

This link covers Asbestos Standard for the Construction Industry which includes: - Removing or encapsulating asbestos-containing material (ACM). - Constructing, altering, repairing, maintaining, or renovating asbestos-containing structures or substrates.

So, there is no pealing paint and any lead paint is then encapsulated.

Sure things like company names, websites, logos are part of the branding concept.....but they dont encapsulate all that branding is. 

Just buy it and encapsulate with spray foam. 

Also to answer your question, the $38K you asked about the encapsulates costs such as insurance, closing fee, and realtor fees and taxes.

Generally speaking, encapsulation is perfectly fine as long as the ACM is not punctured, scraped, drilled into ect.

Light sanding does not impact the structural integrity of structural wood.Following that, a treatment with Kilz or Fosters encapsulating paint on the structural wood is OK as that will ensure that any hyphal matter that you missed does not become further airborne.Mold investigations and remediation are a science.  

Could you just request a scrape and replace treatment and be done with it or encapsulate and sheetrock over the encapsulant?

It's a very complex topic, so it's hard to encapsulate in a short post.
