Legally that means he is not in danger or at risk.I have dealt with drug users and dealers.

You want to talk to your CPA first and foremost you don't want to get in a situation were your deemed a dealer and lose your cap gain tax advantages.that said a take down schedule like this is common in the industry.. although CA usually a million dollar property is not a lot.. vis a vi development ground.. and builder developers there usually stroke a check if needed.I suspect though if your going to sell it in phases.the land would be split into 3 phases and you deed out each phase as he pays if off.. but not individual lots that were your CPA can advise you on dealer status.its common though in these scnerios to have accerlated paymentso you have  3 phases  333k each... you sell first phase for  400k.. second phase for 400k last phase for 200k.. this way you get a premium if he fails to buy the rest of the dirtalso in your contract make SURE you demand that all work product engineering soils geo tech that type of stuff is once paid for your property as well.usually in vanilla real estate transaction on the west coast I don't recommend or see the need for a lawyer but in this case I would find a good real estate lawyer tell him these basic terms and things you need then let him prepare the contract.. hope that helps.. and assuming the dirt is in CA.. of course.

I used a reputable AC dealer.

I think back on negotiating with murderers, meth dealers, wife beaters and folks on house arrest...

I know of a few drug dealers who are making millions of dollars...just because it works doesn't mean its legal or right.

I've talked to two dealers (licensed sellers... you can find them on the NC Ag pages) in NC but haven't been able to get traction yet.

@Rudy Curtler it looks like you may be a mobile home dealer.  

If it were me I’d call your local mobile home dealers and ask for the mason they use and talk with them.

Quite often, you will find a mobile home dealer or hauler that will take the home for and deal with the squatter (that is what the occupant is at this point).  

You and I can't stop Wells Fargo from screwing over their customers at every turn, but we can kick the meth dealers out of our apartment building.
