Seller trying to back out after inspections

[Benjamin Dutil]

Hi BP community. I’m under contract to purchase 2 duplexes. After I had inspections and started the re-negotiations (after the discoveries) the seller wants to back out. I am also a current tenant in the same properties. Big issue is new roofs, plywood included with mold. Second issue is leach fields at the end of their life cycles. What should I do? Please help! Should I continue to try and close? What recourse do I legally have?
