What are your go-to paint colors, brands, flooring, etc..?

[Kirsten Ostby]

I'm soon to be purchasing my 3rd SFH rental, and I've reached the point where I want to start using the same things in every property. Those of you who have multiple units/properties, what are the paint colors and brands you are using? Do you paint the whole interior one color? Or 2-3 colors depending on room type?
How about flooring? Is there a specific carpet you like when it's needing to be replaced. If it helps, my demographic is in the B range, so I'm not looking for anything too elaborate.
