It the contract form is not executed by both seller and buyer, you won't have a binding contract.

The most important thing is to make sure you can execute, that you are working with a qualified contractor (not the cheapest price from a random guy in a beat up van) as the interest can kill your deal if you go to long, and many lenders will call the note due at the end of 12 months.

He may have ment 1 of 2 things ..1)  The house was Foreclosed on and sold at Court House Foreclosure Auction2) The Short Sale lender required the property be sold on an auction site as a Short Sale.Either way it sounds like you didn't have an executed contract and/or have been out of the loop.

You would be getting a HELOC to free up capital to execute on the next deal, so why not just keep that capital free in your own account so you don't have to take out a HELOC and pay the bank interest.  

Carrie, Texas has such restrictive requirements for installment sales (CFDs) that they aren't done, other states are following the foreclosure requirements, new lending rules are also in place, issues of deeds being executed simultaneously are seen as cancelling out each other as deeds may be effective when executed rather than perfected by public notice.

The Buyer at some point subsequent to the execution of the A-B Contract sells their interest in said contract to a third party.    

Enough said, it's an error and no one needs to be executed.
