You put 20k in to buy that house, so that's your 'skin', but you haven't lost it. 

Today I called again, and asked if he wanted to talk.He pretty much got really irritated and said that when I'm actually serious about his house, to come by with a check for 60 Grand and he'll sign the paper.

“You have to have skin in the game.”

Who knows.What really gets under my skin is the lack of enforcement of federal illegal immigration laws on both federal and state level.

The bank wants you to have skin in the game so they won't let you borrow the down payment.

If you are concerned about any of the remaining contamination, after cleaning your residence or rental property, or if your property still has an odor, visible staining, or causes physical irritation to those exposed, it is advisable to have the property tested for chemical residues.

But you will still need some money because they want you to have skin in the game plus see reserve funds.

He can absolutely leave a very disgusting mess if I don't clean up after him, feces and skin he sheds. 

I drove around for years in NY and Miami finding great deals for others before I finally had the confidence to risk my own skin.

This is a business where thick skin is pretty essential.
