My sister just purchased a house where there was a playset and a storage shed in the the yard. Several listing photos were also of these two items. After signing a contract, the owners sold the playset. It was a nice wooden one and they got $750 for it. It was not on an exclusion list for items not conveying.
Both realtors are being laissez faire about it. One said pictures don't count for anything. Sis more irritated over the principal of the matter. They do have grandchildren that would have used the playset though.
