This seems like a risky deal, but a good one because there's someone who might have some title to the land who wants me to have it, the quit claim deed is so cheap and there are no back taxes.Note: I do not have enough capital to fund a construction project immediately, but I could start the adverse possession statute of limitations by fencing and clearing the lot.What am I missing?

Two of them were “3rd offerings” so I take possession immediately without the year grace period.

The writ was issued and we got possession.  

[pics forthcoming once I have them in my possession]

But I think you have adverse possession if it’s been like that for 100 years.

The sellers want to know that YOU have the money in your possession..

It did not take my long to get an email from my broker with evidence of the license in his possession.

Of the 6 units, 2 are in good standing with their lenders (i'm one of the two), 2 have been foreclosed and are in the bank's possession and 2 have lis pendens and will soon be in the bank's possession.  

You would approach your "new real estate partner" with the facts: You've (hopefully) got a record 1/2 undivided interest AND possession and his share is worth much less that 1/2 of ARV due to the following list of reasons...It's no longer a dispute between two spouses and does not have to be emotionally charged or difficult to resolve and attorneys CAN be avoided IF a realistic resolution is agreed upon.Remember: you didn't cause your current seller's problem and they have nothing without your help.

@Markus March You don't say if the tenant is asking you to replace their possessions or not.
