@Nick Stageberg I've found issues with electrical that will not support modern living standards. 

The electricity isn't knob and tube and doesn't present much difficulty to maintain and modernize, the plumbing is all pretty simple (single stack).

For example a dated kitchen with walls yellow from cigarette smoke and a 60 year old oven is fine, a kitchen that you can't cook food in is not fine -- even if it is otherwise modern, new, and clean. 

There are many ways to build and customize the containers to make the home look really modern and nice so I think it's great for short term rental.

Since the only things I have seen so far that weren't holding up are those they have been done in the last decade, I would have to lean way towards the 93 yr old parts being much safer than the 13 yr old crap.Of course, I had to mention the whole part about it being a fire trap, which seems to be what helped burn Chicago down back in the day, But with modern tech, that shouldn't be as worrisome as back then.Anyone with anything you think I should know, need to , or what to know about balloon framed houses.  

Historic preservation is not an issue, so it could be completely demolished and modernized.

LOL.This is something I would recommend every REI do before they buy into a market for a rental(s):1 - Find out the day the court is doing evictions (usually it's an all day thing...and the same day(s) every week/month.2 - Clear your schedule for the day3 - Go to the court, bright and early that day4 - Bring a pad of paper and pen (remember how those worked...they still do), because most courts won't let you bring your tablet, laptop, phone...into court.5 - Sit in the middle of the room6 - Watch and listen7 - Take notes (see #4)8 - Learn.
