A picture may not be worth a thousand words.

Probably to appeal to prospective buyers who think they can get a property for a great price if they're willing to do a little fix-up.

Richard, when we have a true "fixer upper" or a house that only a contractor should be looking at...we would post a photo like that one.  Disclosing everything.  I'd rather the customer see this up front and be prepared for it, then show lovely photos of the few places that are in good shape and blindside the buyer when they get there!

Looks a little more like what you would see in an inspectors report.

What not to do in construction example, or for sale for DIY or fixer upper????

Hmmmm   I've seen the same thing recently.  A home a seller wanted to sell but did not want to put the baseboards back down.  They removed them to replace tile and have not replaced them yet and want to list?  No thank you I said.
