Circular Deposits and Fund Sourcing: What Lenders Need to Verify

What Are Circular Deposits?

A circular deposit occurs when money is transferred between two or more related accounts and counted as income or new funds — when in reality the same money is just moving in a circle. For example, a borrower transfers $20,000 from their savings account to their checking account to inflate the checking account balance before applying for a loan.

The money isn't new — it was already in the borrower's possession. Counting it as income or new deposits overstates the borrower's financial strength.

Why Fund Sourcing Matters in Mortgage Underwriting

Mortgage guidelines — particularly those from Fannie Mae (FNMA) and Freddie Mac (FHLMC) — require lenders to verify that funds used for down payment and closing costs come from acceptable sources. This protects against:

• Undisclosed borrowed down payments that increase the borrower's actual debt obligations
• Artificially inflated bank balances designed to pass the asset verification requirement
• Money laundering through real estate transactions

How Lenders Detect Circular Deposits

When underwriters see large deposits in a bank statement, they look for corresponding withdrawals from other disclosed accounts that match the deposit amount and timing. The process:

1. All accounts must be disclosed on the loan application
2. Underwriters cross-reference deposits in Account A against withdrawals in Account B
3. Round-number same-day or next-day transfers raise immediate questions
4. Lenders may request 60–90 days of statements to trace the full movement of funds

Acceptable Fund Sources

Fannie Mae and most conventional lenders accept these fund sources for down payment:

• Savings (seasoned at least 60 days)
• Checking accounts (funds properly sourced)
• Retirement accounts (with documentation of withdrawal/loan)
• Gifts from family members (with signed gift letter and proof of transfer)
• Sale of assets (with documentation of sale)
• Proceeds from sale of prior home

Unacceptable or Problematic Sources

• Undisclosed loans from individuals
• Borrowed funds (unless properly documented as a secured loan against another asset)
• Cash with no verifiable source
• Transfers from entities the borrower owns (may indicate business funds being used)

The Seasoning Requirement

Funds that have been in the borrower's account for at least 60 days (the standard seasoning period) generally do not require sourcing documentation — the lender assumes they've been adequately verified over time. The 60-day rule exists specifically to prevent last-minute fund manipulation for loan applications.

How AI Helps with Fund Sourcing

Manual fund sourcing review across multiple accounts and 60–90 days of statements is extremely time-consuming. AI tools like StatementScrub automatically flag large deposits, identify same-day offsetting transactions between accounts, and highlight patterns that suggest circular fund movement — significantly accelerating the underwriting process.
