Magic colors?

[Bill Briscoe]

I'm doing my first investment rehab (I've worked on a couple houses while I've lived in them before, but nothing this extensive all at once). Just closed yesterday. This is a lower middle class but mostly tidy neighborhood, late 80's construction.

I'm aiming for modern but inexpensive finishings as we are on a fairly tight budget (most of it is going to AC/roof etc). What wall/trim paints, door hardware, fixtures, colors, etc would best fit that description?

Is there a Home Depot "white" that every one uses on trim? I'm thinking Defiant Satin Nickel doorknobs. Any other advice?
