What the Survey Is
The Freddie Mac Primary Mortgage Market Survey, often referred to as PMMS, is a weekly report tracking average mortgage interest rates offered by lenders in the United States.
It is conducted by Freddie Mac, formally known as the Federal Home Loan Mortgage Corporation. Established in 1970, Freddie Mac is a government-sponsored enterprise created to promote liquidity and stability in the U.S. housing finance system.
The PMMS focuses on conventional, conforming mortgage products that meet specific underwriting standards. Its long-standing methodology has made it one of the most respected benchmarks for mortgage rate data.

How the Survey Works
Freddie Mac collects mortgage rate data each week from a sample of lenders across the country. The survey reflects rates that lenders offer to borrowers with strong credit profiles and a loan-to-value ratio of approximately 80 percent.
Freddie Mac averages the results and publishes them publicly, typically every Thursday. Each release reports the average interest rate and associated points for products such as the 30-year fixed-rate mortgage and the 15-year fixed-rate mortgage.
Because the survey follows consistent assumptions, it enables reliable comparisons over time instead of mirroring daily market volatility.
Mortgage Products Covered
The survey most commonly highlights the 30-year fixed-rate mortgage. Many American homebuyers choose this loan because it offers predictable payments and a long repayment period.
The survey also tracks 15-year fixed-rate mortgages, which usually carry lower interest rates but require higher monthly payments. During certain periods, Freddie Mac includes adjustable-rate mortgage products as well.
By maintaining standardized loan characteristics, the PMMS keeps its averages consistent and comparable from week to week.
Why the Survey Matters
Mortgage rates directly affect monthly payments, housing affordability, and overall purchasing power. Even small rate changes can significantly influence long-term borrowing costs.
The Freddie Mac Primary Mortgage Market Survey gives borrowers and analysts a reliable reference point to determine whether rates are rising, falling, or stabilizing.
Financial news outlets regularly cite the survey when covering housing trends. Economists and policymakers rely on it to assess broader economic conditions, including inflation trends and monetary policy effects.
Benefits for Homebuyers
Prospective buyers use the survey to gain transparency about national mortgage trends before contacting a lender. It helps them understand the broader lending environment.
Although personal rates vary based on credit score, debt levels, and location, the PMMS provides a dependable benchmark. Buyers can compare current averages with their financial situation to evaluate affordability.
Many borrowers also monitor weekly releases to help decide when to lock in a rate.
Insights for Homeowners and Refinancers
Homeowners considering refinancing often consult the survey for guidance. When average rates decline, refinancing activity usually rises.
The survey also offers valuable historical context. By comparing today’s rates with previous years, homeowners can evaluate whether refinancing could generate meaningful savings.
Because the PMMS maintains decades of archived data, it allows borrowers to see how current rates compare with past economic cycles.
Historical Perspective
The Freddie Mac Primary Mortgage Market Survey has tracked mortgage rates since the early 1970s.
During the late 1970s and early 1980s, inflation pushed rates to historic highs. In contrast, the early 2020s brought some of the lowest mortgage rates in modern history before inflation and Federal Reserve policy shifts drove them upward.
This extensive historical record helps analysts study trends across economic expansions and recessions.
How It Differs From Daily Rate Quotes
Many online platforms advertise mortgage rates that update daily or hourly. These figures often reflect promotional pricing or specific borrower scenarios.
The PMMS focuses on consistency rather than real-time fluctuation. It applies standardized assumptions and aggregates lender data to create reliable averages.
As a result, borrowers should treat it as a benchmark rather than a personalized quote.
Limitations to Understand
Although widely respected, the survey cannot reflect every borrower’s situation. Credit scores, down payments, loan sizes, and geographic differences all influence actual rates.
The survey also captures a snapshot of lender data during a specific week. In fast-moving markets, lenders may adjust rates more quickly than the published averages suggest.
Recognizing these limits helps borrowers interpret the data with realistic expectations.
Role in Economic Analysis
Economists closely monitor mortgage rate movements because these rates shape housing demand and construction activity.
Higher rates often reduce affordability, which can slow home sales and refinancing. Lower rates tend to encourage borrowing and increase purchasing power.
By releasing consistent weekly data, the Freddie Mac Primary Mortgage Market Survey supports economic research and market forecasting.
How to Use the Survey Effectively
Buyers and homeowners should treat the survey as a reference tool rather than a final decision point. It provides valuable context for conversations with lenders and financial advisors.
Instead of reacting to a single weekly change, borrowers should observe trends over several months to understand broader market direction.
When borrowers combine survey insights with a careful review of their personal finances, they make stronger and more confident mortgage decisions.
