Contengency period Help!

[Danushka Abeyasekera]

I have a 5-day inspection contingency period and on the 5th day I messaged by broker saying I need 50k back towards the deal due to excessive repairs. Escrow is asking me to release contingencies on the 6th day, however my broker has not yet presented my request officially. Do I have to sign the release of contingencies thus effectively losing any negotiation powders or could I be able to not sign it and not lose the deal?
