How to Price a Mortgage Loan 2026: Secondary Market Pricing and Margin

Understanding how mortgage pricing works from secondary market to borrower quote is essential for competing effectively. Most MLOs quote rates off a rate sheet without fully understanding what drives the numbers. That gap shows up in your ability to explain pricing to borrowers and to compete on margin when you need to.

MBS Pricing Drives Base Rates

Mortgage rates are priced off the mortgage-backed securities (MBS) market. When MBS prices rise, mortgage rates fall. When MBS prices fall, rates rise. Lenders issue daily rate sheets that reflect current MBS pricing plus their internal margin and risk adjustments. Rate sheet prices are expressed as a price per $100 face value: a price above 100 means a credit (rebate to borrower); a price below 100 means a cost (points to borrower).

Par Rate, Points, and Lender Credits

The par rate is the rate at which the lender's pricing is exactly 100: no points charged, no rebate paid. A rate below par requires the borrower to pay discount points. A rate above par generates a lender credit that can be applied to closing costs. The relationship between rate and price is not linear; it varies based on expected prepayment speeds for each rate tier.

• ✦Discount points: 1 point equals 1% of loan amount paid upfront to lower the rate
• ✦Lender credit: premium generated when rate is above par; applied to offset borrower closing costs
• ✦Break-even calculation: divide points paid by the monthly savings to determine payback period

LLPAs and How They Affect Your Quote

Fannie Mae and Freddie Mac apply Loan-Level Price Adjustments (LLPAs) to conventional loan pricing based on FICO score, LTV, property type, occupancy, and loan purpose. These adjustments are additions to the base price. A 680 FICO borrower at 80% LTV pays a different LLPA than a 760 FICO borrower at the same LTV. Some LLPA waivers apply to first-time homebuyers at or below area median income limits.
