With metal work or trim work, $400 sounds pretty reasonable, assuming your using a good window and not a piece of garbage single pane. 

The inspector found a couple of cracked window panes.  

The main things they look for:- Windows - double pane or better (this includes basement windows)- Attic insulation- Doors - checking for storm doors or weatherstripping.

. ($4k)The windows seem to work, but about 5 window panes are broken. ($2k)No appliances provided, so new appliances should be installed. ($2k)A few smaller odds and ends with broken cabinet doors etc, but fairly minor. ($1K)That's probably at least $15-20k work there.

A good quality triple pane fibreglass window, the kind you would use in a Passivhaus build or retrofit - will run you $50 - $75 per ft^2.  

You are going to have to remove people in units, overcrowding does strain the system.  

Nah guys, my bad, miscommunicated....Each panel is 60amps.I guess the problem lies in the way the electric makes it to the panels inside the building:The lines are buried in a 2in pipe in foundation cement up until the panels.

They'll check to make sure the panel is labeled as well.

The one point I'd want to make is that the price you quoted to upgrade an electrical panel is closer to retail pricing, and an investor who find a good electrician who is accustomed to working with investors should be able to get it done in your area for about half that price.

There are different grades of vinyl, but in general I see more seal failure in vinyl than wood and that causes that cloud in  between the panes of glass.
