Instead of wood (which would have easily been $6K installed, I opted for Water-resistant 12mm Laminate which luckily I found on sale, and in stock near by, so that is going in soon (see pix for details). 

However I want you to be as profitable and move along the path of least resistance as possible.

Anyone who whines, cries, grumbles, and resists when it comes to fixing their own errors has to go.  

From there select the real estate investment niches that allow you to achieve your goals with the least amount or resistance.

Does not make sense to me.Would you let them paint the bathroom with mildew resistant paint and cupboards at my expense?

Usually aluminum siding with paint that is oxidizing leaves the residue...if it was alum. we'd wash it really well then prime and paint.

I would use either cement board or mold resistant board (purple board) at a minimum.

The one that looks interesting is the air type that oxidizes the water coming in and then filters it out then back washes the filter.  

It's not waterproof of course, but since water seeks the path of least resistance, keeping it in plain sight (i.e., on the finished floor) increases its chance of being wiped-up or evaporating.  

I have just finished putting down 3 pallets of laminate in some of my rehabs, the most important things to look for are length of tongue (the short tongues have a tendancy to want to snap, plus they can move eisier), resistance to moisture, and of course looks.
