"Rented FMV 299 days"

There seems to be no unoccupied dates at all, which is unlikely. Also, there seems to be a missing preposition or adjective or verb. Is that "Was rented at Fair Market Value for 299 days" or perhaps "It would rent for $X and would be computed as if it had been rented for the remaining 299 days."

When you ask peer users for help, the details matter.
