What to do about a concrete slab listing that is not actually a concrete slab

[Klemont Wright]

Went and took a look at a property today that is listed as having a concrete slab foundation.

The home shows all the signs of foundation issues on the exterior, and interior.

Upon closer inspection, we were able to remove a loose brick at the very bottom near the "foundation".......we were able to see that the house is built on wood beams, supported by cinder blocks.

The outer edge (about 6 inches in width) of the "foundation" is concrete, as if they poured concrete just to support the perimeter of the home.

Question.......how would this issue be fixed with sagging beams underneath the property? There's not much room underneath, and the only thing I could see is someone would have to address the beams from inside the house (removing the flooring). Anyone else dealt with this before?

Thoughts, ideas?
