Foundation problem after purchase.

[Suduk N.]

Hi All,

I have recently purchased an investment multi family house 2 flats with a legal basement in Chicago, IL. I'm regutting the place then to find out there is a foundation problem that has caused the house to sag in the middle about 3 inches from the roof to the floors. 

The seller indicated no knowledge of the foundation problem in the disclosure. I have a couple of questions

1) Do you guys know any foundation engineer or company that I can contact to determine the severity of the problem and get a quote for repair. 

2) Under IL law, can I hold the seller accountable for all or some of the cost of repair? 

Thanks,
