Open Question: Is it legal for a seller of a home in florida not to fix unsafe issues?

I recently got a house inspected and two major safety issues came back. 1) the electrical is not up to code on 3 breakers, two wires to one breaker and 2) the toliet pipes are leaking underneath the house which has caused dry rot in the master bedroom. I think the first is a fire hazard and the second is a health code violation, but I could be wrong. The seller refuses to fix these issues or lower the price. Is this legal for the seller to refuse to fix these issues? I have a baby on the way and are concerned over these issues.
