I tried to go into the attic to view this from the inside but I couldn’t tell what was going on because there was a lot of insulation and drywall from the high ceilings of the house in the way.

I had tenants replacing ceiling lights with ceiling fans, and when they leave, take the ceiling fan with them because they say it belongs to them, leaving wires sticking out of the ceiling.

That "tin ceiling" is for the inevitable leaks from the bath in the unit above!

They mentioned boiler was looking kind of corroded roof probably would last five years… We knew those things, but other things happen before we could even get to those- now we are face to face with them after ac unit leaking into ceiling below and everything else- I feel like we’re pretty much gonna have to just get through it… Even if we sold, we would have to pay capital gains taxes wouldn’t we?

I can do floor to ceiling windows in the room to open the space up if need be. 

Ceilings collapsed.

Also they need to ensure that when they take the property back, there isn't enough money to pay the other liens and those get wiped out.Just last week there were about 43 properties up for Auction, only 2 received more than the bank's opening bid, because the price was just to high.So, do your homework, know your ceiling on your price, and if it doesn't happen, know that the property will come back months down the road as a REO.

Walls, ceilings, trim, doors, everything gets the same white (for same reason Mike said - easy touchup).

Always look at the ceilings. 

Maybe you want to install ceiling fans in more rooms.
