Wall/pantry that separated kitchen from living room was demoed (you still can see on a floor where it used to be).

If the floor is humped you can repair the spot effected by demo and replacing  and then sanding entire floor. 

county has all sales either online or at the courthouse.comp demo costs by calling demo companies and get there ballpark figures including removal and disposal.

Demo - cost, number of dumpsters, time start to finish, crew size, landscape clean-up 3.

Found out there were "code issues" on the property, yet the buyer would have been willing to DEMO ALL structures, JUST to appease code enforcement & get the land!!!!  

Either do as @Tom Mole said and just demo the lower, or demo and do a rebuild of the upper to make it big enough to take up the space that the lower occupied. 

If your doing a lot of demo some of the other filled units will probably move out due to the inconvenience any way.

The demoed down to the studs, then left the house standing long enough for people to break in, have parties, squat and wreak general havoc. 

One of the topics covered was master lease options, or sandwich lease, and as he was doing a demo on how to pitch it.

Copper is still there but the dishwasher has been pulled away from the wall and a cabinet is damaged (suspect Bidder 2 was rough in his inspection, but kitchen needs demo so this is not a concern.)
