Contract for deed signed feb 2011. Seller to close end of feb 2011. Buyers payment date at time of closing was to be changed to the 3rd of every month however the contract for deed does state the first plus late fees if paid after the first. Seller could not close with their atty office because they could not agree on the terms of the contract for deed. Now one year later seller is threatening late fees because they get paytment on the third. How can seller hold the late fees against me when they get full payment every monthwhen they did not close to begin with?
