My gut tells me you will have to "allocate" a portion of your sales price to the land and any improvement made more than 12 months before you sold and then allocate a portion to the buildings you put up within one year of selling.

The rest of the expenses will be part of the basis of the property and depreciated over 27.5 years (for residential rentals) along with the part of the purchase price that is allocated to the building.
