Overview

A mortgage broker bond is a surety bond that NMLS-licensed mortgage brokers post to obtain and keep their state license. It guarantees that the broker will follow state mortgage law and treat borrowers fairly. If the broker violates the rules and causes a loss, a claim can be made against the bond up to its amount.

State regulators set the required bond amount, and it varies by state and sometimes by loan volume. Because the bond guarantees the broker's conduct, underwriting focuses on the owners' credit and the firm's financial standing rather than on insuring a particular risk.

It is a surety bond that protects borrowers and the regulator. When the surety pays a claim, the broker repays it under the indemnity agreement.

How a surety bond differs from insurance

A mortgage broker bond protects borrowers and the state, not your firm. It is a surety guarantee of compliant conduct, while errors and omissions insurance covers your own liability for professional mistakes. They serve different purposes and brokers often carry both.
