How Lenders Verify Your Bank Accounts and Assets
When you apply for a mortgage, your lender needs proof that you have enough money for your down payment, closing costs, and reserves. Fannie Mae gives lenders several ways to verify your assets, and understanding these options helps you prepare the right documentation.
The most common method is providing bank statements. Your lender will ask for statements covering the most recent two-month period for purchase transactions or one month for refinances. These statements must be complete — no missing pages — and show all deposits and withdrawals during that period.
Say you're buying a home and applying for your loan on March 15th. Your lender will want to see January and February bank statements in their entirety. If you're refinancing, they'll typically only need the February statement.
What Your Bank Statements Must Include
Every statement you provide must meet specific requirements. The statement needs to clearly show the name of your bank or credit union, identify you as the account holder, and include at least the last four digits of your account number.
The statement must also show the time period it covers and include your ending balance. For checking and savings accounts, all deposits and withdrawals must be visible. For investment accounts, all purchase and sale transactions need to appear.
Computer-generated statements work fine, including those you download from your bank's website. The key requirement is that the document clearly identifies your financial institution. When you print statements from online banking, make sure the bank's name appears somewhere on the document — usually in a header or footer.
Alternative Verification Methods
Instead of bank statements, your lender might use Form 1006, the Request for Verification of Deposit. This form goes directly from your lender to your bank, and the bank sends the completed form directly back to the lender. You never handle the document yourself.
Some lenders use third-party verification services that electronically access your account information with your permission. These services must provide the same information that would appear on Form 1006 or your bank statements.
If your lender also holds your deposit accounts, they can generate their own verification directly from their system. This internal verification must include all the same details required from external statements.
When Statements Are Too Old
Your bank statements can't be stale. If your most recent statement is more than 45 days old when you apply for your loan, your lender will ask for a more current document.
This supplemental document doesn't need to be a full statement. A simple bank-generated form showing your account number (last four digits), current balance, and the date will satisfy the requirement. Many banks can provide this type of verification letter or balance confirmation.
This rule exists because account balances can change quickly. A statement from two months ago might not reflect your current financial position, especially if you've been saving for your down payment or had major expenses.
Special Rules for Different Transaction Types
Purchase transactions require more documentation than refinances because buyers need to prove they have funds for their down payment and closing costs. Refinance borrowers typically need less cash at closing, so lenders require shorter documentation periods.
For accounts that report quarterly instead of monthly, you'll provide the most recent quarterly statement regardless of whether you're purchasing or refinancing. This exception recognizes that some investment accounts and retirement plans don't generate monthly statements.
Retirement account statements have additional requirements. They must show your vested amount — the portion you actually own — and the terms for accessing those funds. See B3-4.3-03: Retirement Accounts for specific retirement account rules.
Desktop Underwriter and Asset Validation
If your loan goes through Fannie Mae's Desktop Underwriter (DU) system, different rules might apply. DU can validate some assets electronically, which may reduce your documentation requirements.
When DU validates your assets, following the system's specific messages satisfies Fannie Mae's requirements. These DU requirements might differ from the standard documentation described above. Your lender will tell you if DU validation applies to your loan.
For more details on DU asset requirements, see B3-4.4-02: Requirements for Certain Assets in DU and B3-2-02: DU Validation Service.
Common Documentation Problems
Missing pages cause the most problems with bank statement verification. Lenders need complete statements — they can't accept partial documents even if the missing pages seem unimportant.
Faxed or emailed statements sometimes lose clarity, making account numbers or bank names hard to read. When sending electronic copies, ensure all text remains legible and the financial institution's name is clearly visible.
Large deposits that appear on your statements will trigger questions. Your lender needs to document the source of any significant deposits to ensure they represent legitimate funds, not borrowed money that would affect your debt ratios.
Joint accounts require special attention. If you share an account with someone who won't be on the mortgage, your lender may need additional documentation to verify your access to those funds.

Verification of Deposits and Assets
Asset Documentation Provided by a Third-Party Asset Verification Vendor
Verification of Deposits and Assets
The lender can use any of the following types of documentation to verify that a borrower has sufficient funds for closing, down payment, and/or financial reserves:
Request for Verification of Deposit (
Form 1006). The information must be requested directly from the depository institution, and the complete, signed, and dated document must be sent directly from the depository institution.
Copies of bank statements or investment portfolio statements. All statements must:
clearly identify the financial institution,
clearly identify the borrower as the account holder,
include at least the last four digits of the account number,
include the time period covered by the statement,
include all deposits and withdrawal transactions (for depository accounts),
include all purchase and sale transactions (for financial portfolio accounts), and
include the ending account balance.
If the lender is the holder of the borrower's account, the lender may produce a printout or other alternative verification of the asset(s) directly from its system. The printout or alternative verification is acceptable as long as all required data (above) is supplied and documented.
Copies of retirement account statements. They must be the most recent statements, and they must identify the borrower’s vested amount and the terms. (See
B3-4.3-03, Retirement Accounts, for additional information.)
The number of required bank or investment portfolio statements varies per transaction type as shown in the following table.
Purchase transactions
The statements must cover the most recent full two-month period of account activity (60 days, or, if account information is reported on a quarterly basis, the most recent quarter).
Refinance transactions
The statements must cover the most recent full one-month period of account activity (30 days, or, if account information is reported on a quarterly basis, the most recent quarter).
If the latest bank statement is more than 45 days earlier than the date of the loan application, the lender should ask the borrower to provide a more recent, supplemental, bank-generated form that shows at least the last four digits of the account number, balance, and date. The statements may be computer-generated forms, including online account or portfolio statements downloaded by the borrower from the Internet.
Documents that are faxed to the lender or downloaded from the Internet must clearly identify the name of the depository or investment institution and the source of information—for example, by including that information in the Internet or fax banner at the top of the document.
If necessary, the lender must supplement these verifications by obtaining any missing information from the borrower or the depository institution.
See B3-4.4-02, Requirements for Certain Assets in DU, for additional information about documentation of assets for DU loan casefiles.
In addition, loans with assets validated by DU must comply with all requirements pertaining to the DU validation service. Compliance with the DU messages satisfies the requirement for documenting assets. This documentation may differ from the requirements described above. See B3-2-02, DU Validation Service
Asset Documentation Provided by a Third-Party Asset Verification Vendor
Direct verification by a third-party asset verification vendor. These verifications are acceptable as long as:
the borrower provided proper authorizations for the lender to use the verification method,
the verified information provided must conform with the information that would be provided on Form 1006 or on bank statements,
the date of the completed verification is in compliance with
B1-1-03, Allowable Age of Credit Documents and Federal Income Tax Returns,
the lender has determined that the vendor maintains reasonable practices that ensure reliable and authorized verifications of deposit and asset information (see
A4-1-01, Maintaining Seller/Servicer Eligibility), and
the lender understands it will be held accountable for the integrity of the information obtained from this source.
Blanket Authorization Form
Rather than having the applicant sign multiple forms, the lender may have the applicant sign an authorization form which gives the lender blanket authorization to request the information it needs to evaluate the applicant’s creditworthiness. (See B1-1-02, Blanket Authorization Form.) When the lender uses this type of blanket authorization, it must attach a copy of the authorization form to each Form 1006 it sends to the depository institutions in which the applicant has accounts.
