Repair misunderstandings

Question:  Buyer and Seller are under contract.  During Buyers Due Diligence, Buyer sends an addendum asking Seller to complete three specific repairs.  Seller never responds or agrees to the repairs.  What happens to the contract?

Answer:  YOU STILL HAVE A CONTRACT. Just because an addendum attempting to modify an existing REPC expires, this DOES NOT mean the entire REPC falls apart. You simply keep the same existing terms of the REPC. Sellers do not have to agree to proposed contractual modifications to the REPC, but they do have to honor what they have already agreed to.
