What Does an Underwriter Actually Want From Your Bank?
The underwriter’s main goal is to verify the accuracy of your financial statements—they call your bank to check deposits, account balances, and verify any outstanding liabilities tied to the property.
In the first round of underwriters, they’ll focus on proof of funds and confirm that your savings and investment accounts match the figures on your application.
Secondarily, the underwriter assesses your liquidity by confirming that any pending large withdrawals or planned purchases won’t jeopardize your ability to repay the loan. This early bank verification helps eliminate surprises when you move into the closing phase.
Because underwriters work under strict timelines, the airline of verification usually takes about 48–72 hours—if your bank is responsive, of course.

Typical Information an Underwriter Requests
Moving forward, here’s a list of the most common document types they’ll need confirmation on:
- Statement of Deposit History: Verification of consistent deposits over the past 12 months.
- Outstanding Balances: Loans, lines of credit, or credit cards tied to the property address.
- Change of Occupancy: Evidence that the property remains vacant or owned.
- Property Mortgage Values: Current market appraisal or automated valuation model (AVM).
These item lists help the underwriter quickly cross-check that your financial picture matches the paperwork submitted. Often, the lender will provide a simple “yes/no” or a balance figure directly to the underwriter.
Because the bank must upload the data to the lender’s system, any mismatched numbers can trigger a delay or request for additional documentation, so double‑check your spreadsheets beforehand.
To help you get these details in order, many banks offer an online portal where you can generate a statement ID that the underwriter can pull instantly.

When Does the Underwriter Typically Call?
In most mortgage processes, the underwriter’s initial bank call lands after the original application is approved and before the final underwriting decision.
Most underwriters follow a phased approach:
During the pre‑underwriting stage, the lender does a quick screen—this is when your bank may be asked to provide a verification of employment and income if your pay stubs trail off or you’re self‑employed.
During the underwriting stage, they may need a full financial profile to ensure your debt‑to‑income ratio remains below 43% in most loan programs.
And in the final underwriting stage, a quick follow‑up call typically confirms that the property’s title and insurance documents match the bank records.
Impact on Your Credit Score
Some borrowers worry that a verification call will ding their credit. The good news: underwriters use hard inquiries sparingly, except for credit checks when you’re applying for a new line of credit or a power‑of‑attorney form.
The small table below shows how a bank call can affect your score in different scenarios.
| Scenario | Credit Impact |
|---|---|
| Standard Underwriting Call | 0 – No hard inquiry |
| Income Verification Request | 0 – Soft inquiry only |
| New Line of Credit Approval | Potential - One hard inquiry |
Because these are routine checks, the impact on your credit is typically minimal or none. If you’re concerned, you can request a soft inquiry or the lender to send you a copy of the inquiry before it’s posted.
How to Prepare Your Bank for the Call
One of the best ways to reduce friction is to start your own internal audit a week before you submit the application.
- Make sure your banking history shows at least three months of consistent deposits.
- Identify any large, upcoming withdrawals and inform your lender.
- Gather statements in PDF format and restrict them to the compliance window (e.g., last 90 days).
- Check with your bank whether they can provide a “verification letter” that the underwriter can download directly.
By following these simple steps, you’ll typically get a smooth bank verification call and a cleared underwriting decision.
What Happens If Your Bank Doesn’t Respond?
Sometimes the underwriter can’t reach the bank and must issue a “delayed underwrite.” In that case, the lender will mark the loan as “Pending” and request you to submit additional documentation.
Statistically, about 12% of mortgage applications experience a delay due to communication issues with lending institutions.
You can reverse this by proactively checking the bank’s contact details, making sure the account number and routing information are correct, and asking your bank to flag the account for prompt responses.
Even if the underwriter holds off, the final decision will still come sooner if your bank provides the needed data quickly.
Prepared borrowers who keep bank and lender communication lines open save an average of 3–5 days in the approval timeline.
Next Steps: Leveraging the Bank Call to Your Advantage
Use the bank verification call as a chance to double‑check your loan amount. If you see a discrepancy in your deposit balance, you can correct it before closing. Even small adjustments can prevent a costly post‑close note.
Also, you’ll learn how many lenders use third‑party data warehouses like CoreLogic or Experian Boost to cross‑verify information. These systems feed the underwriter’s engine with real‑time data, speeding up the whole process.
After the bank call, keep an eye on the underwriting portal your broker or lender offers—you’ll see a “bank verified” status that will push you one step closer to closing.
Finally, when the underwriting is done and the loan is approved, you’ll receive an e‑signing package with the closing documents. The whole mortgage cycle will finish up in a few days if all the paperwork strips are clean.
In short, a bank verification call isn’t a hurdle—it’s a routine part of validating your credibility, ensuring you get the best rate, and moving toward that closing day. Stay prepared, keep your records tidy, and the underwriter’s call will be your ally, not the enemy.
