Here are a couple articles you may enjoy (hopefully you can sneak some reading time when your son is sleeping!)

Any other buyer will need time to do DD and may end up backing out like I did... so maybe they will just come down and be done with it so they don't have to disturb the tenants more than necessary.

Yes, also to disturb tenants less by working above them.Maybe you could gut the whole building first, so that your plumber and HVAC guys could get those systems done first, then do the finish work one unit at a time.

Help I am loosing sleep over this.

BUYER IS NOT TO DISTURB OCCUPANTS.

Are you able to sleep at night peacefully?

I wouldn't be able to sleep at night if I was stealing from other people.

For example, right now I'm laying here with a sleeping kid on my arm watching Thomas the Tank Engine as I type this (I can post now because I've already seen this episode :D)...my next post will probably be while I'm sitting at a railroad crossing on the way to my son's school waiting for a train to pass...then I'll post again from Costco while following my wife around the store...

If so, was he sleeping on the balcony so that the repairs interrupted his lifestyle?

LOLMany,many crooks out there.I am not sure how they sleep at night without thoughts of becoming friends with Jimmy Hoffa real soon.
