The process

What happens during underwriting?

Educational guide · Updated 2026

Underwriting is the stretch between your accepted offer and your closing day where the lender verifies everything and makes the final decision. It's often the most anxiety-inducing part of the process, mostly because it happens behind the scenes and can feel like silence. Here's what's actually going on.

What the underwriter is checking

The underwriter's job is to confirm that the loan meets guidelines and that you can repay it. They review four main things: your income and employment, your assets (that you have the funds for the down payment and closing), your credit history, and the property itself — confirmed by the appraisal.

The three possible outcomes

Underwriting generally ends in one of three ways. Approved means you're cleared to close. Conditionally approved — the most common outcome — means you're approved as long as you provide a few more documents or explanations. Denied means the loan didn't meet guidelines, though sometimes the issue can be fixed and resubmitted.

Why they keep asking for more documents

Conditional approval often comes with a list of "conditions" — a recent pay stub, a letter explaining a large deposit, an updated bank statement. This is normal, not a red flag. The single most useful thing you can do is respond quickly, because the clock on your closing date is often waiting on these.

How long it takes

Underwriting typically takes a few weeks, though it varies by lender and how complex your file is. The biggest variable is usually you — how fast you return requested documents. A file where the borrower responds same-day moves much faster than one where each request sits for days.

What not to do while you wait

This is the worst possible time to change your financial picture. Avoid opening new credit cards or loans, making large purchases (especially financed ones like a car), changing jobs, or moving large sums of money around without a paper trail. Any of these can change the numbers the underwriter is working from and force them to start parts of the review over — or worse, jeopardize the approval.
