Duplexes are ancient and most are run down, that I have seen.

Some of the plumbing is ancient and there's evidence that some parts have had to be repaired already.  

Also of note:  the door to the lobby from the mudroom (first image in this post) is a nice 36" steel door with a deadbolt; the door to the lobby from the present kitchen is an ancient 30" solid wood 4-light paned door that will need to be replaced (pictured in OP).I apologize if I keep throwing up all over your ideas, Z.   

well when you travel through Europe  Italy and Greece in particular you will see laundry hanging out on the line in front of these great ancient homes. up here in Orygun well we don't do that much unless you want to grow moss on your clothes..plus in many areas of the US your just inviting the petty thieves to steal your skinny jeans

The HVAC is ancient, but works well right now. 

For example, this is an ancient slate roof that needs repairs after last winter, but I want to replace it- so I ask for the money for the repairs for damage during winter.And with improvements, I like the idea of phasing things in as the current stuff wears out so as to not shock the rentability of the unit in a mediocre rental market.
