How DU Determines Your Asset Documentation Requirements
Desktop Underwriter analyzes your loan application and tells your lender exactly what asset documentation you need to provide. The system looks at your transaction type, loan amount, and down payment to determine the minimum verification requirements.
For purchase transactions, you'll need two consecutive monthly bank statements showing 60 days of account activity. If you're refinancing, DU typically requires only one monthly statement covering 30 days of activity.
Say you're buying a $400,000 home with a $80,000 down payment. DU will require your lender to verify that you have the funds for your down payment, closing costs, and reserves. You'll need to provide two months of bank statements for all accounts you're using for the transaction.
When DU Waives Asset Documentation
DU can waive asset documentation entirely for certain refinance transactions. If the total funds you need to verify are $500 or less, the system may not require any asset documentation at all.
This typically happens on limited cash-out refinances where you're rolling closing costs into the loan amount and need minimal cash to close. Your lender will still need to calculate your funds to close, but DU won't require bank statements or other asset verification.
Bank Statement Requirements and Timing
Your bank statements must be current when you apply for your loan. Monthly statements need to be dated within 45 days of your initial loan application date. If you're using quarterly statements, they must be dated within 90 days of application.
Your lender must also confirm that funds shown on quarterly statements haven't been transferred to another account that's verified with more recent documentation. This prevents you from moving money around to inflate your asset picture.
A Verification of Deposit (Form 1006) can substitute for bank statements. Your lender sends this form directly to your bank, which completes it and returns it directly to the lender. This eliminates any concern about altered statements.
Special Asset Categories and Entry Requirements
Bridge Loans and Swing Loans
Enter bridge loan amounts in section 2a of your loan application as a separate asset type. Don't include the same money in both a bridge loan entry and a checking account balance.
If you're selling your current home and buying a new one simultaneously, the bridge loan amount must be subtracted from your net equity calculation for the pending sale. This prevents double-counting the same funds.
Earnest Money Deposits
Earnest money goes in section 2b of the loan application and reduces your required funds to close. The system assumes your earnest money check has cleared your bank account, so don't include this amount in your bank account balances.
Your lender needs documentation showing you actually made the earnest money deposit. This usually means a copy of the cancelled check or a receipt from the title company or real estate agent.
Gifts and Grants
Gifts and grants are entered in section 4d and marked as either "deposited" or "not deposited." If you've already received and deposited gift funds, include the amount in your bank account balance but don't count the gift amount separately in available funds.
If the gift hasn't been deposited yet, don't include it in your bank account balance, but DU will count the gift amount toward your available funds for closing.
Proceeds from Property Sales
Properties Already Sold
If you've already sold a property, the proceeds must be sitting in a depository account like checking or savings. You'll need bank statements showing the deposit and any subsequent activity.
Your lender will want to see the settlement statement from the sale to verify the net proceeds amount. Large deposits that don't match expected sale proceeds will require explanation.
Properties Pending Sale
For properties you're selling concurrent with your purchase, calculate the net equity outside of DU and enter it in section 2b using the asset type "Proceeds from Real Estate Property to be Sold on or Before Closing."
Net equity equals your expected sale price minus your existing mortgage balance, selling costs, and any bridge loan amount. If the calculation results in negative equity, DU subtracts this amount from your available funds.
Other Liquid Assets and Personal Property
You can use proceeds from selling personal assets like cars, boats, or jewelry for your transaction. Enter the expected proceeds in section 2b using "Proceeds from Sale of Non-Real Estate Asset."
DU will require evidence of the asset's value and confirmation that you converted it to cash before closing. This might include an appraisal of valuable items and documentation of the actual sale.
Life insurance cash value is entered in section 2a using the "Cash Value of Life Insurance" account type. You'll need documentation from the insurance company showing the available cash value and any loan restrictions.
Secured Borrowed Funds and Asset-Backed Loans
You can borrow against assets you own, such as 401(k) accounts or investment accounts, to fund your transaction. Enter the loan amount in section 2b as "Secured Borrowed Funds."
Subtract the borrowed amount from the asset's total value when entering the remaining asset balance. If you have $50,000 in your 401(k) and borrow $15,000 against it, enter $15,000 as secured borrowed funds and $35,000 as retirement funds.
Loans secured by liquid assets like retirement accounts don't need to be entered as liabilities if you provide proper documentation. However, loans secured by real estate must be entered as mortgage liabilities in the appropriate section.
When DU Validation Overrides Standard Requirements
DU's validation service can sometimes verify your assets electronically through direct connections with financial institutions. When this happens, DU issues a message indicating what documentation is acceptable for your specific situation.
If DU validates your assets electronically, following the validation message requirements satisfies the documentation requirement, even if it differs from the standard bank statement requirements described in the guidelines.
This validation can streamline your application process, but it's not available for all borrowers or all financial institutions. Your lender will know whether validation is available for your accounts.
Common Documentation Pitfalls
Large deposits that appear on your bank statements without explanation will delay your loan approval. Your lender must source and document any deposit that's not clearly from employment or other verified income sources.
Transferring money between accounts during the application process can complicate verification. If you move funds, your lender needs to track the money trail to ensure you're not borrowing undisclosed funds or inflating your asset picture.
Cryptocurrency, foreign bank accounts, and other non-traditional assets require special handling. These assets may not qualify for your transaction or may need additional documentation beyond standard bank statements.

Asset Verification Documentation
When DU requires assets to be verified, DU will indicate the minimum verification documentation requirements necessary for the lender to process the loan application. This level of documentation may not be adequate for every borrower and every situation. The lender must determine whether additional documentation is warranted.
DU will not require documentation of assets for refinance transactions when the total funds to be verified are $500 or less.
Depository Assets
For depository assets (checking and savings accounts, money market funds, and certificates of deposit), DU will require the following:
two consecutive monthly bank statements (60 days of account activity) for all purchase transactions, or
one monthly statement (30 days of account activity) for all limited cash-out and cash-out refinance transactions.
Monthly bank statements must be dated within 45 days of the initial loan application date.
Quarterly bank statements must be dated within 90 days of the initial loan application date, and the lender must confirm that the funds in the account have not been transferred to another asset account that is verified with more current documentation.
A Verification of Deposit (Form 1006) can be obtained in place of bank statements.
When DU validates assets, DU issues a message indicating the acceptable documentation. Compliance with the DU message satisfies the requirement for documenting assets. This documentation may differ from the requirements described above. See B3-2-02, DU Validation Service.
Bridge Loan
Enter the amount of a bridge (or swing) loan in the asset section 2a of the loan application. Do not include the amount of the bridge loan in any other liquid asset. (For example, do not enter the amount of the loan both as a bridge loan and in a checking account, even if the loan funds have been deposited.)
Bridge loans should also be considered in the net equity calculation for properties that are pending sale. (In other words, the amount of the bridge loan should be subtracted from the net proceeds to avoid counting this asset twice.)
See B3-4.3-14, Bridge/Swing Loans for additional information.
Note: It may also be necessary to enter the bridge loan and corresponding monthly payment as a recurring liability in the liabilities section of the loan application. See the bridge loan liability discussion in
Cash Deposit on Sales Contract (Earnest Money)
Earnest money is entered in Section 2b in the loan application. It is treated as a credit to the transaction and will reduce the borrower’s required funds to close as reflected in Section L4. The earnest money check is assumed to have cleared the borrower’s bank account and must not be reflected in the balance of an asset account.
See B3-4.3-09, Earnest Money Deposit, for documentation requirements.
Gifts and Grants
Gifts or donations from entities (grants) are permitted and documented in accordance with B3-4.3-04, Personal Gifts, and B3-4.3-06, Grants and Lender Contributions.
Gifts and grants are entered in Section 4d of the loan application and identified as being deposited or not deposited. Gifts and grants that are deposited have been received by the borrower and the value should be included in another asset account. The amount of the gift or grant is not included in available funds.
Gifts and grants that are not deposited are not included in another asset account. The amount of the gift is included in available funds.
Gifts of Equity
Enter a gift of equity in Section 4d of the loan application.
A gift of equity must meet the gift of equity requirements defined in B3-4.3-05, Gifts of Equity.
Net Equity from Properties Pending Sale
See B3-4.3-10, Anticipated Sales Proceeds, for additional information.
The lender must calculate the net equity outside of DU for a property marked Pending Sale in Section 3 of the loan application. The amount is entered in the asset section (2b) using the asset type Proceeds from Real Estate Property to be Sold on or Before Closing.
If a bridge loan is obtained, the amount of the bridge loan is entered as an asset and must be subtracted from net equity before entry in the loan application.
When the net equity is positive, DU will add the amount to the funds available for closing. When the net equity is negative, DU will subtract the amount from the funds available for closing.
Proceeds from Sold Properties
Proceeds from properties that have already been sold must be included in a depository account, such as a checking or savings account.
Other Liquid Assets
Enter the value of personal assets that will be converted to a liquid asset (or sold) prior to closing in Section 2b using the asset type Proceeds from Sale of Non-Real Estate Asset. (See B3-4.3-18, Sale of Personal Assets, for additional information.) Life insurance that will be used for the transaction is entered in Section 2a using the account type Cash Value of Life Insurance. An Other Asset (liquid) may be entered for other types of assets that will be used for the transaction, such as pending tax refunds that will be received prior to closing.
A verification message will require evidence of the value of the asset and confirmation that the asset was converted to cash.
Secured Borrowed Funds
Borrowers can borrow against an asset they own, such as a 401(k) account or real estate, according to the requirements of B3-6-05, Monthly Debt Obligations. The amount of the secured loan should be entered in Section 2b using the asset type Secured Borrowed Funds. The secured loan amount should be subtracted from the market value of the actual asset, and the net asset value should be entered. For example, if the borrower has a vested value, less taxes and penalties, of $30,000 in a 401(k) account and borrows $10,000 against the 401(k), enter $10,000 as secured borrowed funds and enter $20,000 as retirement funds.
A loan that is secured against a liquid asset owned by the borrower (such as a 401(k) or mutual fund) does not have to be entered as a liability in the loan application if the appropriate documentation is provided.
Loans that are secured against real estate, or any other non-liquid asset, must be entered as the applicable liability (for example, as a mortgage).
