Lead based paint Seller knew and did not disclose

[Philip Hernandez]

What's up BP community.  I just bought a property that literally 2 days after we closed on it the tenants informed us that the city had cited the owner for lead based paint, and that it had to be remediated.  The owner having been cited by the city did not disclose to us that he knew about the lead based paint.  The document that we signed on our Purchase and Sale Agreement stated that it "may be present" 

We are now in the process of remediating the issue and will have specialists take care of this.

Question:  Should I take legal actions against the seller since he knew that there was lead based paint, and did not disclose?
