I'm not a structural engineer, nor do I know how the floor is constructed, so I don't know what the complexity or cost of regrading the floor would be. But, for sure, it's not a small thing that could be fixed for a few thousand dollars. Having to redo the doors (if the floor is lowered) will ensure that it's $20K minimum, but it could be $50K or $100K (or more) once you address the structural aspects.
