Apparently this creates a chimney like effect that quickly pulls the flames upwards.

The plank itself is glue down, water resistant, 2 mm.

Kwikset's states on their website that they are drill resistant and pick resistant, but I've drilled them and I've picked them.

Begin with the flaming desire to be of service to this homeowner.

It is no wonder that we are like moths to a flame.

I would think vinyl stick squares would be the cheapest water resistant flooring but it wouldn’t look great over the cracks in the planks.

I wouldn't touch it unless you fully understand the quiet title suit process.Talk with a real estate law professor at your local university (they're usually quite helpful).My lawyer would tell me to stay away... you usually go for tax-deed sales that provide the least resistance (unless you have reserves for litigation).

I know a lot of people swear by laminate and vinyl floors in rentals, but only tile will match up to polyurethaned-in-place solid wood for durability, versatility, repairability, and pathogen resistance.

It is equally probable we will remove the existing hydronic lines and radiators and install heat pumps with electric resistance auxiliary heat.3) Plumbing:  The sewer main is cast iron, as is the main stack, but most of the smaller runs are ABS.  

If it's wholesaling, expect resistance from 80% of the people you talk to.
