Also, Kyle- I am trying to nail this down to specifics so I can learn more.

Here is the method I use to nail down my rehab costs:1.

I'd say the key will be to nail down a niche and get started.

My understanding is the asbestos particles could possibly be released if, say a nail was pounded into he wall to hang a picture, or someone cuts into the wall. 

@Nicholas L. nailed it lol it's not the calculator it's the market! 

- You've nailed it.

@wes brandYou got the nail on the head when you said that if they can't afford to carry the loss is not for them...

@Sam SwizzleYou nailed it.

(which I think is what @James Wise is talking about).One thing to keep in mind is that "Poor People" (yes I know, Escalades and nails and etc...) will be happiest (stay longer) in a neighborhood where they have the services they need, such as clinics, liquor stores , pawn  shops, buy here pay here, rent to own--type of shops, vs. higher end things, like Neiman Marcus, where they can't afford to buy anything.              

Get a sample and try to scratch it with your nail, coin, key, etc.
