Frequently asked questions

What is a bank statement loan?

A non-QM mortgage that uses bank deposits instead of tax returns to document income, common for self-employed borrowers.

What expense factor is typical?

Lenders often use a flat 20 to 50%, or a CPA-prepared expense ratio. Your lender decides, so confirm theirs.

Which deposits should be excluded?

Transfers between your own accounts, loan proceeds, refunds and one-time non-business deposits.

Is this a lender qualification?

No. It is an estimate. Lenders review statements line by line and apply their own overlays.
