A large deposit is most commonly defined as a single deposit exceeding 50% of the total monthly qualifying income, though the exact threshold varies by loan program and whether the deposit is being evaluated as an asset or as income.
Guideline Requirements
Fannie Mae — Asset Context (B3-4.2-02)
- "A large deposit is defined as a single deposit that exceeds 50% of the total monthly qualifying income for the loan." Fannie Mae
- Applies on purchase transactions only when funds are needed for down payment, closing costs, or reserves. Fannie Mae If a large deposit is not documented, verified funds must be reduced by the amount (or portion) of the undocumented large deposit, and the lender must confirm that the remaining funds are sufficient for the down payment, closing costs, and financial reserves. Fannie Mae B3-4.2-02
- Refinance transactions: No documentation or explanation required (though borrowed funds must still be tracked). Fannie Mae
- Split deposits: When a deposit has both sourced and unsourced portions, only the unsourced portion is used to determine whether the 50% threshold is met. Fannie Mae
FHA — Forward Mortgages (TOTAL and Manual Underwriting)
- Same 50% threshold under both TOTAL and manual underwriting: "For individual deposits of more than 50 percent of the total monthly Effective Income, the Mortgagee must obtain documentation of the deposits." FHA 4000.1 II.A.4.d.iii FHA 4000.1 II.A.5.c.iii
- Also requires verification that deposits are commensurate with the borrower's income and savings history and that no debts were incurred to obtain part or all of the Minimum Required Investment.
FHA — Title I Manufactured Home Loan Program (separate from Title II forward mortgages)
- Title I manufactured home loans use a loan-amount threshold: "For recently opened accounts and recent individual deposits of more than 1 percent of the loan amount, the Lender must obtain documentation of the deposits." FHA 4000.1 II.E.4 Forward mortgages use the 50 percent of total monthly Effective Income rule above under both TOTAL and manual underwriting. FHA 4000.1 II.A.4.d.iii FHA 4000.1 II.A.5.c.iii
Freddie Mac — Purchase Transactions and Asset-Based Qualification
- Income-based benchmark for purchase transactions: the Seller must document the source of funds for any "large deposit" that is needed to qualify the Borrower and was made no more than 60 calendar days preceding the Application Received Date. Freddie Mac 5501.1(f) A "large deposit" is any single deposit exceeding 50% of the sum of the total monthly qualifying income for the Mortgage Freddie Mac 5501.1(f) and, when assets are used as a basis for repayment of obligations, the amount derived from the asset calculation for establishing the DTI ratio. Freddie Mac 5501.1(f)
- Asset-based benchmark only when assets are used as a basis for repayment (stable monthly asset qualification): "The Seller must document the source of funds for any deposit exceeding 10% of the Borrower's total eligible assets in depository accounts and securities and verify the deposit does not include gifts or borrowed funds or reduce the eligible assets used to qualify the Borrower by the amount of the deposit." Freddie Mac 5307.1(c)
Lender Overlays / Matrix

Exceptions / Alternative Paths
- Greenbox / Newfi — Bank Statement Programs: Isolated large deposits must be sourced or excluded.

Greenbox Newfi Lending Newfi Lending
- AmWest Bank Statement Advantage: Sourcing is explicitly waived — no documentation required regardless of deposit size. AmWest

- Note: Fannie Mae, Freddie Mac, and FHA forward mortgages all use a threshold of 50% of total monthly qualifying income (FHA: Effective Income). Fannie Mae B3-4.2-02 Freddie Mac 5501.1(f) FHA 4000.1 II.A.4.d.iii The differences are in when the rule applies: Fannie Mae applies it on purchase transactions when the funds are needed for the down payment, closing costs, or financial reserves Fannie Mae B3-4.2-02; Freddie Mac applies it on purchase transactions to deposits needed to qualify the Borrower that were made no more than 60 calendar days preceding the Application Received Date Freddie Mac 5501.1(f). Freddie Mac's 10% test applies only when assets are used as a basis for repayment Freddie Mac 5307.1(c), and FHA's 1 percent of loan amount test is the Title I manufactured home loan rule, not the Title II forward mortgage rule FHA 4000.1 II.E.4. Several Non-QM programs listed above also use 50% of monthly income; a small number of Non-QM lenders apply a business-income benchmark or waive the requirement entirely.
