Mortgage Broker Channel Economics: Margin, SRP, and Comp

The economics of the mortgage broker channel look simple on the surface but have layers that affect pricing, competitiveness, and long-term viability.

How Wholesale Pricing and SRP Work

Wholesale lenders price loans at par (zero points) and offer borrower-paid or lender-paid compensation. When a broker originates above par, the premium becomes the service release premium (SRP), which represents the value of the mortgage servicing rights embedded in the loan. The lender captures the SRP, not the broker. A broker choosing the lender-paid comp model receives a flat basis point spread, typically 100 to 175 bps, regardless of the rate. A broker choosing borrower-paid comp can charge up to the TILA cap (3% on conforming) and shop the rate more aggressively.

Comp Plan Math: BPC vs Borrower-Paid

• ✦Lender-paid comp (BPC): predictable, lower ceiling; good for high-volume commodity-rate transactions
• ✦Borrower-paid comp: flexible ceiling; good for complex or niche loans where the LO adds significant value
• ✦You cannot legally switch between the two on the same loan after intent-to-proceed
• ✦RESPA Section 8 prohibits referral fees; comp must tie to the loan amount, not referral activity

Margin Compression and Channel Comparison

Brokers typically have lower overhead than retail branches, which allows them to price more aggressively at the same comp level. Without in-house processing and underwriting, the broker has less control over cycle time, which affects pull-through and repeat business. The net per-loan margin for a well-run broker shop often lands between 75 and 130 basis points after all costs, compared to 100 to 180 bps for a correspondent lender that retains and releases servicing.
