If they have an Exclusive Right-To-Buy Listing Contract (aka Buyer Agency documents) in place, I have an obligation to present them every deal that matches their criteria in that agreement.

Grab grab your local adjudicated newspaper.

I am exclusively invested overseas at the moment with a plan to expand more out in South America.

I hadn't realized there were folks who exclusively focus on 1031s (which in hindsight, duh!)

Honestly xcel has everything you need if you use it properly.The hardest part will be setting up all the references and equations for your specifications.If that might seem a little too much of a challenge for you I would put an ad into your local college newspaper offering $1000 for an xcel spreadsheet that you can build upon and let a college intern/professor/student build you one for weekend beer money.

Also, an additional deal, if done right, could provide cash flow that he can allocate exclusively to his debt to help pay it down faster. 

Did the original agent leave the brokerage you had the exclusive with?

It's unlikely that any actual tax would be due because of the increased $11.18 million lifetime exclusion, but you're supposed to track the exemption used and technically have a filing requirement.

Unfortunately if you signed an exclusive right to sell with the agent, then it probably says that even if you procure a buyer on your own you will owe the listing agent the 6%.
