Light colors and finishes have been shown to hold their value along with simple hardware and fixtures that are not overly trendy.

It all depends on what your strategy is and how you've structured the digital portion of it. 

Louvers or louvered doors, bought new, will say how many square inches of open area they provide.It is best to get the manual for the exact heater you have from the manufacturer, but if you can't, look at a current similar water heater at the hardware store (size in gallons, fuel, efficiency level) and get the manual for that one.I used to live in a house where the water heater was in a closet behind the laundry room. 

NET-ROI can be double digits if done correctly, depending on location, finishes, etc.  

I like the idea of achieving, on average double digit interests on those investments, and then on occasion when I do get the property because the homeowner doesn't pay their taxes I will then Fix and flip that property.

No dehumidifier was running and anything metal such as door hardware was rusted.
