How long does underwriting take? Underwriting—the process in which mortgage lenders verify your assets to get a home loan—can last a little as two to three days, but typically takes over a week to finish.

Underwriting happens right before you close on a house, so timing can be crucial, particularly if you want to move in by a certain date. But make no mistake: Underwriting is unavoidable. All loans go through an underwriting process before the lender can promise you the funds for a purchase.

While you might have daily contact with your mortgage officer, the underwriting process is long, somewhat secretive, and seemingly mysterious. And very, very stressful! Here’s why it takes so long, and a way to speed up the process.
