You should be discussing this with your agent, broker and attorney. Without all the facts I wouldn't dare to comment. You are in a contract with an agent who is representing you and you need to be discussing this with them. Best of wishes.
Contractually, you have a 17 day contingency period to recieve, review and respond to all disclosures. If you exceed that period, you lose your earnest money deposit.
If the seller signed the request for repairs document, they are required to do the repairs prior to your final walk-thru. Due to your loan requirements, your Realtor should have presented the seller with a Notice to Perform which would give them 72 hours to complete their obligations or you may cancel escrow and have your deposit returned. Did you Realtor send them the notice to perform?
There is a Cancelation of Escrow form that can settle everything if you can get the seller to sign it peacefully. Otherwise, you may end up in small claims. If you're dealing with a bank, it's hard to say. Sometimes they are easy to deal with and some times they are night mare!
I hope that helps!!!
