The dealer offered me $2,000.

IN own there is 5 major players the only bar that has changed hands was 13 years ago and that was a shady place running drugs and now a very succesful place ad I am close with the owner i know his numbers.

Drug house ('In Rem' confiscation)?

It doesn't sound like it was a home poker game that got busted, it sounds like there was a full on casino happening with dealers, etc. and he worked to conceal it.

I would charge much higher rents for pot dealers.

Could be subsidized financing by Invest Atlanta, a few ugly houses on the same block, undesirable historic features like a shared drive, drug deal next door ...

In California, you would be very hard pressed to find a judge that would allow you to enforce a "no marijuana/no drug" clause in your lease for pot (though I've seen it happen, once).

Then asked for Drugs (Meth).
