A lender response that has been accepted can be "un-accepted". Doing so unlocks the deal and allows you to make edits and then re-submit. Un-accept does not send a response to the Lender!
A response that has been accepted displays the Un-Accept
button on the Lender Response screen. To un-accept the mortgage response,
click the Un-Accept button, and
then click OK to the confirmation
message that appears.
