I was in the process of refinancing my mortgage with a lender and had already signed intent to proceed and the disclosure package. Also signed papers for the title company. I recently got laid off so the refinance was not able to go through and the lender put a rate lock extension. They sent over new disclosure package for me to sign. Is it to late to back out and cancel the refi all together? An appraisal had also been done but i have not paid for anything yet. Will I be responsible for any fees?
