The material in between the roof is a weird galvanized tin type of thing that was painted over multiple times... 

Thanks for the material and shedding light on horrible business practices across our nation. 

Bloodhounds and beagles can track specific scents even through the scent blocking charcoal impregnated material so yes it's a very viable option.

When the developers I have worked with do a tear down a place with asbestos and other things costs much more to demolish.You would think you would just tear it down but they want all that remediated and removed first so it doesn't go airborne during the tear down.Building cost 5 years from now is impossible to speculate.Labor and materials could be way up and LEED demands might be a requirement then.Can an additional level be built on the existing structure if it is beefed up at the bottom??

I am looking for some good training material for starting out with wholesaleing.

I didn't think that was unusual, as I've put a buttload on my credit card in the last few weeks on materials for the above-mentioned rehab, but for some reason, I got spooked out and hung up.

Materials and Labor?

It's not that you're prepaying for the material, as it is the labor which is the big expense here.I should have clarified on that.

If you fail to disclose it, a tenant may sue you for concealing a material fact.

But I dont think they MAKE the materials, so its gotta be one of those 2 companies that supplies them.
