Vitality PM me and I can point you in the right direction for that area.

As people that depend largely on the poor to pay their rent (or section 8 which means you are beyond poor) proper adherence to the letter of the law in these matters is vital.

But there is still the cost involved in material and timeIf you do your own maintenance,  then the labor cost is on you.Wood gets scratched up no matter how well you try to refinish it more so that a flooring product that has an AO or double layer of ceramic bead that is factory applied, such as LVT's.

Rent analysis is vital in choosing an area but the type of person you want as a tenant is as equally important. 

This worked well to reduce echo and sound of footsteps.We also put new flooring down for the landings with a noise suppressor layer under it.

They put gypsum boards over real tough southern yellow pine studs, then manually put on a brown coat over an inch thick, then a thin layer of egg shell finish. 

ANY impermeable layer (your wood floors then epoxy) placed over it will accelerate the moisture migration resulting in the delamination of any & all overlays.

You need at least one layer of protection between you(r personal possessions and assets) and your business entity structure (translation: more than one entity)If your businesses are properly established and maintained they WILL afford you considerable (though not "perfect") protection against even the most frivolous of lawsuits.

It depends how many layers on the tear off but it looks like you've got quite a few there.

Resale is not as vital as cash flow because I'm in it for the long haul.
