Renegotiate Purchase Price after Inspection, Sewer Repair

[Brad Garcia]

Have a contract on a duplex- C home in C+/B- neighborhood. 140k contract price based on observable repairs. Inspection showed sewer needed to be repaired which will be assessed to the property – 12k. Is it reasonable to negotiate the purchase price in regards to the new specials? Asking for 5k off the purchase price as I will not need to worry about sewer, but I feel the original contract price assumed there were no big issues. Seller initially came down 5k during initial negotiations. Let me know if I am missing anything… And thanks for any thoughts!
