Large deposit sourcing and seasoning by loan program

Fannie Mae, Freddie Mac and FHA all treat a single deposit over 50% of monthly qualifying income as a large deposit, and Freddie adds asset-derived income to the base. They differ on when the deposit must be sourced. VA sets no numeric threshold. Under Fannie and Freddie, an unsourced large deposit comes out of qualifying assets.

Key numbers

  • >50% of total monthly qualifying income makes a single deposit "large" (B3-4.2-02)
  • 60 days of statements on a purchase; one month on a refinance (B3-4.2-01)
  • 1% of the sales price: FHA verifies the amount and source of earnest money above it (II.A.4.d.i(A))
  • 120 days maximum age of VA statements or a VOD; 180 days for new construction (Topic 4.b)

Program comparison

None of the four sources uses the word "seasoning" for assets. The statement window does that job.

Fannie Mae

The line in B3-4.2-02 is "a single deposit that exceeds 50% of the total monthly qualifying income for the loan." If part of a deposit is documented, test only the unsourced part.

On a purchase, a large deposit used for the down payment, closing costs or reserves must be documented as coming from an acceptable source. On a refinance, large deposits need no documentation or explanation, but "the lender remains responsible for ensuring that any borrowed funds, including any related liability, are considered."

Purchases need "the most recent full two-month period of account activity (60 days...)," and refinances one month (B3-4.2-01). A VOD doesn't show individual deposits, so Fannie tests balances instead, requiring the source of funds when an account was opened within 90 days of the application date, or when its balance is "considerably greater than the average balance."

A source printed on the statement, such as payroll, Social Security, a tax refund or a transfer between verified accounts, is enough unless borrowed funds are suspected. Where documentation is incomplete, Fannie allows "reasonable judgment" on evidence such as a written explanation, proof that an asset was sold, or a wedding invitation, as long as the lender's written rationale is in the file. When DU validates assets, it flags the large deposits that need documentation, and following the DU messages meets the requirement.

If a deposit can't be sourced, verified funds "must be reduced by the amount (or portion) of the undocumented large deposit." Confirm the rest still covers the down payment, closing costs and reserves, and that underwriting, manual or DU, used the reduced figure.

Freddie Mac

Freddie's base is bigger: 50% of the sum of total monthly qualifying income and any amount derived from assets under Section 5307.1. For a partly verified deposit, the Seller "may use just the unverified amount" (5501.1(f)(ii)).

Freddie generally doesn't require a source, though the Seller must consider liabilities from borrowed funds. There are two exceptions, in 5501.1(f)(i)–(ii). On any transaction, a deposit used to pay off or pay down debt in order to qualify must be sourced. On a purchase, a large deposit needed to qualify must be sourced when it was made no more than 60 calendar days before the Application Received Date and on or before the Note Date, and it appears on documentation in the file. Since Bulletin 2026-9 (July 1, 2026), the same large-deposit rules apply to accounts held outside the United States and its territories.

Statements run one month for Streamlined Accept documentation and two months for Standard (5501.3(a)). With a VOD on a purchase, Freddie requires the source when an account was opened within 90 days of verification, or when the current balance exceeds the average by more than the large deposit amount (5501.1(e)(ii)).

Only three sources are acceptable: the borrower's income; funds awarded to the borrower by a party that is not an interested party; and eligible assets under 5501.3 and 5501.4 (5501.1(f)(iii)). An unverified deposit reduces the funds used for qualification, and Section 5101.3 governs whether the loan must be resubmitted to LPA.

FHA

FHA's rule is "individual deposits of more than 50 percent of the total monthly Effective Income," the same for TOTAL loans (II.A.4.d.iii(A)(2)) and manually underwritten loans (II.A.5.c.iii(A)(2)). It doesn't distinguish purchases from refinances, and it doesn't address partly sourced deposits.

The mortgagee must verify that deposits "are commensurate with the Borrower's income and savings history and no debts were incurred to obtain part, or all, of the MRI." Earnest money has its own test: verify the amount and source if the deposit exceeds 1 percent of the sales price or is excessive given the borrower's savings history (II.A.4.d.i(A)).

The file needs a VOD plus the most recent statement, or a third-party verification covering at least the most recent month. Without a VOD, it needs a statement showing the previous month's ending balance, or else two months of statements (II.A.4.d.iii(A)(3)).

The Handbook sets no reduction rule for an unsourced deposit. Its Defect Taxonomy lists "Large Deposits" as a source under Borrower Assets and rates unverified assets Tier 2 or Tier 3, depending on whether the borrower likely had enough funds from an acceptable source (Appendix 8.0).

VA

Chapter 4 doesn't define a large deposit. The lender verifies all liquid assets needed to close, plus any "significant assets" that bear on the credit analysis, using a VOD or the last two bank statements, no more than 120 days old (180 days for new construction) (Topic 4.b). For AUS loans, that's one month of statements for an Accept and two months for a Refer (Topic 8). Any undisclosed debt a bank statement reveals must be resolved. Beyond that, an unexplained deposit is underwriter judgment.

Gifts

Every program requires a gift letter and evidence of the transfer: Fannie B3-4.3-04, Freddie 5501.4(a), FHA II.A.4.d.iii(F) and VA Topic 4.d. Freddie accepts money-transfer apps only if the file shows the funds went directly from the donor's bank account. FHA does not accept cash on hand as a donor's source. Since July 1, 2026, Freddie also accepts a gift from a business owned by a Related Person, if the gift letter states that person's ownership interest and that person signs it (5501.4).

Worked example

Illustrative numbers. On a purchase, the borrower has $6,000 in monthly qualifying income and no asset-derived income. The checking account holds $40,000, and funds to close plus required reserves total $33,000. Two deposits fall inside the window: $4,500 with no source shown, and $2,000 printed as payroll.

The threshold is 50% × $6,000 = $3,000 under Fannie, Freddie and FHA. Exactly $3,000 does not exceed it; $3,000.01 does. The $2,000 payroll deposit is below it and identifiable. The $4,500 deposit is large. If it stays unsourced under Fannie, verified funds drop to $35,500. That still covers the $33,000, and underwriting must use $35,500.

If $2,000 of it is documented, say as a tax refund, only $2,500 is tested. That's below $3,000, so under Fannie and Freddie it's no longer a large deposit. Under FHA, the $4,500 deposit must be documented, and the Handbook is silent on partly sourced deposits.

The lender remains responsible for its underwriting and QC decisions.

How Flightline checks this

Large deposit sourcing and bank statement transaction math are two of Flightline's asset tests, next to reserves calculation, and its undisclosed-debt tests look for "debt implied by deposits." Flightline "follows evidence across the file": statements, gift letters and the application, and verifies its conclusion before raising a finding.

FAQ

Does Fannie Mae require large deposits to be sourced on a refinance?

No. The lender must still consider any borrowed funds and the related liability (B3-4.2-02).

How far back does Freddie Mac look?

On purchases, to deposits made no more than 60 calendar days before the Application Received Date and on or before the Note Date, when the funds are needed to qualify (5501.1(f)(ii)).

Does VA have a large deposit threshold?

Chapter 4 does not state one. The lender verifies the liquid assets needed to close and any significant assets, and resolves any undisclosed debts a bank statement reveals (Topics 4.b, 5.a).
