During the mortgage process, your lender will review your bank statements to verify your financial information. Sometimes, they may ask about a large deposit that appears in your account.
This is a normal part of underwriting and happens often.
What Is a Large Deposit?
A large deposit is a deposit that is greater than 50% of your monthly income. Example: you make $10,000 a month, any deposit over $5,000 is considered a “large deposit”
Common examples include:
- Cash deposits
- Transfers from another person
- Venmo, Zelle, or Cash App payments
- Checks deposited into your account
- Sale of a vehicle or personal property
- Gift funds from family
- Transfers between accounts
Why Does the Lender Need It Explained?
Mortgage lenders are required to verify where your funds came from before approving your loan. This helps confirm the funds are from an acceptable source, that the money is not undisclosed borrowed funds, and that your loan file meets federal lending guidelines.
If a large deposit cannot be properly documented, the lender may not be able to use those funds toward your mortgage approval.
If a large deposit cannot be documented, the lender may not be able to use those funds toward your mortgage approval.

Depending on the situation, this may include:
- Copy of a check
- Deposit slip
- Bank statements showing a transfer
