In all seriousness, the properties banks are holding are imminently going on the market. Most have already been on the market as short sales, go off, then back on very shortly after the bank takes possession. They need to be considered as inventory.
jpinpb, I think you're confusing "future inventory" with "inventory". "Future inventory" is useful information when you're trying to forecast the market. People should definitely be aware of it. But you shouldn't use "future inventory" to calculate the "months of supply" because "months of supply" has a very specific definition. Changing the definition of a well known term will confuse people rather than enlighten them.
