Repainted cabinetry and all walls.

Removed a pony wall, replaced all flooring, re-painted, fixed A/C and water heater, got rid of horrible cat smell.

Rehabbed Kitchen, bathroom and repainted entire inside and out of home.

I was cash flowing about $700/month and that includes my HELOC interest on the purchase price.Tenant moved out and we're investing around $6K (mostly materials, we're DIY) on new flooring for the living room, total repaint of the interior, and new kitchen cabinets. 

I would just sand and repaint the cabinets to a light gray if that is not your style then stair a mahogany color.

You'll have drywall cracks, so you should factor in drywall repairs and repainting. $$$4.

White ceilings, semi gloss white trim, and a very pale grey on walls.It simplifies repainting, and purchasing paint.

While living in the house, we made a few updates: we removed old paneling, we added a safe, and we repainted the house.

In other words, after 3 years, tenants are generally not charged to repaint unless there is actual damage to walls, not regular wear and tear.And regarding your #5 and #6, since the Landlord agreed for your early move out, s/he cannot now hold you liable for it.
