Contract Change after Clear to Close

[Ramit Agrawal]

Lender delayed the process and we got clear to close after the planned closing date. We now have a new contract with the seller. The purchase price of house has not changed in this new contract, however the closing date is obviously different and there is a $20k penalty for the delay. Will any of this trigger the need for another round of underwriting? My lender says underwriting won’t be required (since it is still well within the limits of what lender has ascertained as my ability to pay based on my assets) but wanted to double check with the community here.
