A lot of discussion around scenario's that are extremely rare and very unlikely to happen. I've been on this board for several years, and have bought from an international seller. I don't recall any buyer ever having to pay the 15%.
I've only seen others, like me, who have gotten correspondence from IRS. Also, like me, the 15% had been withheld correctly. The title company responded to the IRS notices. End of story, no problem for the buyer.
Too much worry about something that probably won't happen. I might get hit by lightning today, but I'm not going to prepare against it.
