First, check out the link on the RIGHT to your "Total Cost Analysis". This tool provides a transparent view into payment, cash to close and summarizes various options for your scenario.
Next, I have provided documents, including your pre-approval letter for your review and download. First, the "Lender Pre-approval Letter" to supplement with any offers and provides an outline of communication and accolades for the list agent as it can be as much about the offer price as it is about the lender in the current real estate environment. Second, the "Borrower Pre-Approval Letter", which should be a stand alone document that is complete by itself. The third and final document, if applicable for your scenario, is the Loan Consultation notes for specifics to the pre-approved scenario.
