I must say it looks much better with a fresh coat of paint.

Also, I watched a well-respected long-time company install some laminate in one of my rentals and noticed that after they had the sink opening cut, and before they attached anything to the countertop, they rolled a coat of clear polyurethane over all the vulnerable cut edges - the sink opening, underneath the dishwasher, at the 45 joints - and let that dry before finishing up the install.

@John FiastroGo with the hardwoods it will reduce your ongoing costs.We do a light buff and then put several poly coats to seal the floors against liquids (beer, urine, juice etc.)Another great product is vinyl allure flooring.

Painter comes in paints the 5 walls she painted with out approval  ( 2 coats ) , he cleans up the paint she got on the recently done ( 1 year) wood floors .  

So, since it's already been cleaned at least twice, why not just coat over it with a black asphalt topping.  

We had a microwave/oven combo that was totally destroyed and had to be replaced (never cleaned, internal coating melted off and rusted).

Takes one coat with a good quality paint!

Now one of the tenants is leaving and left cigarette burn holes all over the floor and the walls are absolutely coated in tar/nicotine.

I make a plastic tray out of that thicker clear non-adhesive shelf liner to protect the cabinet from leaks.  

Over time you'll hopefully get thicker skin and not get so worked up over issues.
