Like painting over a stain that would reveal a roof leak.I typically would nicely tell them that you did your due diligence and hired a professional to assess it pre-close.

Here are the needed and OPTIONAL repairs as well as their estimated prices:-OPTIONAL Roof needs to be replaced in maybe 10 or so years, it has moss on it now but I can just clean that off for now, so I would say optional for the near term. 10-15K-OPTIONAL: Two of the windows in the living room are failing and need to be replaced if I want people to be able to see through them (condensation stains on the inside of the panes).

I buy that sort of themed artwork on ebay and make frames myself with a table saw, lumber, wood stain and urethane. 

Sand it down, stain it, urethane it. 

So I think its too late to apply any more stain.

It keeps all the moisture/stains/dirt on top of the pad and away from the sub floor so that it can be cleaned out or evaporate up instead of down.I work in a flooring store and I do this stuff all day long. 

Looks like I have to be actively involved to build the community and rekindle threads.The photos I've seen appear to have missing stucco & staining along the bottom exterior walls (that back alley garage) that make it look like nothing but aged rotting which likely will invite termites. 

With a wood deck, you need to power wash / stain etc.

From the termite inspector, there doesn't appear to be active termites, but there are "Evidence of termites staining, partial shelter tubes observed sheetrock in closet by front door and in access panel to tub".

The IRS views this exactly as if you were buying wood, nails, and stain, making tables and selling them.
