If Buyer chooses to seek financing, Buyer may do so at Buyer’s sole risk and expense by submitting a mortgage application to a mortgage lender or mortgage broker within five business days from the date of this Agreement, but the failure to apply for or secure financing in the amount or time or terms desired by Buyer shall not excuse Buyer from timely performance of all obligations under this Agreement.
