I get that it's stressful and unjust, you're not the first person to go through it and there is light at the end of the tunnel.

here are some nice examples of light contrasting/modern style on Tudor style houses on Pinterest--https://goo.gl/KSZVHq

Hello, I'm working on a project right now, and the walls in each of the rooms are painted similar colors (shades of a light grey), however, the ceilings were left an offwhite color. 

Triplexes for example.. need stand alone fire monitoring system (e.g. panel) and some of the newer builds, etc will require sprinkler systems to be installed, shared walls between units must all be fire rated (including all doors), emergency lighting required w/exit signs in hallways, etc etc.

Hopefully I can shed some light on your questions. 

I own an office building with lights in the Parking area and the halls, Common restrooms for offices on the same floors, also water on the hallway.

Sellers routinely inflate their numbers to put the property in the best light but I think your evaluation is probably off as well.

How do you determine if drywall/sheetrock should be replaced or is it possible to lightly sand and do new texture?

We have a 2 flat with a crawl space and when I sent our plumber down there to repair a sewer issue he sent me pictures of 15-25 rat burrows under this building and he saw them all retreat into the burrows when they shined light on it.
