My 1946 built home has a 2" drop near the west, north and south walls. Away from the walls it appears level. The soil in the area is soft and all concrete driveways in the area are cracked and the outside stucco of the house is cracked near the ground level. The pilings, flooring and support under the house are good. The footing has some cracks but appears good other then being too low./GEH

"The pilings, flooring and support under the house are good. " not if you have a 2" drop along three walls. Before leveling the floor I'd look into jacking the joists from below.
