Give the lender clear notice that you want to move forward with the loan by calling, emailing, or texting within ten days of applying. Otherwise, the lender might not know you want the loan and cancel it mistakenly.
Clear notice can be a phone call, email, or text message to the loan officer handling your loan. By contacting the loan officer directly with your intent to proceed, he knows to start working on it immediately.
Most lenders include a form with their Loan Estimate. Signing it signals to the lender that you accepted their deal and want to move forward. I shared a copy of our form below.
