first, it's not buffet's seritage company. buffet (in his own account) purchased an 8% interest in seritage and subsequently agreed to provide $2 billion in financing from another berkshire entity.
sears owns its 2.2 million sf headquarter's complex in hoffman estates and i believe under terms of the stalking horse agreement that will be acquired by esl. not sure what percentage of the remaining properties which are subject to the stalking horse agreement are owned versus leased but that is certainly subject to a fact search as opposed to speculation.
again, while you have repeatedly asked for others to provide comparable retailers, the fact is that what happened to ggp and might possibly happen to sears probably indicates there really aren't a lot of comparables. so, if you are unable to provide any such examples, it would seem sears, like ggp, might in fact be situations where there are almost no comparable examples which is why there might be some hope for sears, much like there was for ggp.
