I walked into a new development to view a home. After hearing so many good incentives, I agreed to purchase the home. We completed paperworks, and I signed and initial documents. I also agreed that I would return a few days later with a cashier check for the earnest money. After showing the home to my family, we decided that when I returned with the earnest money, before releasing the check we wanted the builder TO AGREE to do a few more things. If the builder refuse can I back out of the agreement to buy the home.
