Jupiter allows you to export your loan application as either a 1003 (PDF) or MISMO (XML) file at any time.
When exporting a MISMO file, you'll be asked to select the destination. This helps Jupiter generate a file that is optimized for the lender, underwriting tool, pricing engine, or loan origination system you're sending it to, reducing the chance of upload errors.
