Fannie Mae and Freddie Mac play different roles in homebuying. Understand how each one affects your mortgage so you can feel confident when exploring your options.
At-A-Glance
- Fannie Mae and Freddie Mac are government-sponsored enterprises (GSEs) that buy, back, and sell most U.S. mortgages, helping keep them available and affordable.
- These GSEs buy mortgages from lenders to hold or repackage as bundled investments, which helps keep money flowing between borrowers, lenders, and investors.
- The main difference between Fannie Mae and Freddie Mac is that Fannie Mae usually buys loans from larger institutions, while Freddie Mac often targets smaller ones.
Imagine sitting at your kitchen table for your monthly budget review. While you sip your coffee and leaf through bills, you open a notice from your mortgage company: Your bank sold the loan to Fannie Mae. You’ve been making on-time payments for over a year, so what does this mean?
Who is Fannie Mae, why is Freddie Mac also coming to mind, and what do they have to do with your mortgage?
What Are Fannie Mae and Freddie Mac?
Congress created Fannie Mae in 1938 and Freddie Mac in 1970; both are government-sponsored enterprises (GSEs) designed to stabilize the housing market.1 They provide that stability by buying mortgages from financial institutions and providing those lenders with fresh cash to continue issuing new mortgages. However, they do not issue loans directly to borrowers.
Here’s how it works:
- Lenders issue loans (known as primary mortgages) to thousands of buyers, then supply the money for houses up front, which requires massive amounts of cash.
- To preserve the cash flow necessary to continue issuing loans, lenders might sell those primary mortgages to aggregator organizations like Fannie Mae and Freddie Mac.
- Fannie Mae and Freddie Mac then take those loans and convert them into mortgage-backed securities (MBSs), a fancy term for bundles of individual primary mortgages.
- The GSEs place those MBSs on a secondary market that consists of loan originators, GSEs and other aggregators, and investors.
- Investors buy MBSs because they pay a fixed interest rate, they’re relatively low risk, and they can be more lucrative than, say, a U.S. government bond.2
- The mortgage issuer and the GSEs receive sale funds to continue secondary mortgage market activity while investors earn a yield over time, and the borrower continues making their payments.
- The process repeats, and the housing market hums along.
Fannie Mae Vs. Freddie Mac Comparison
The main difference between Fannie Mae and Freddie Mac comes down to where they source their loans.
Fannie Mae
- Primarily purchases mortgages from larger commercial banks.
- Lately, Fannie Mae has bought up more single-family home mortgages, though it also buys multifamily housing loans, the kind you take out for townhouses or condos.3
- Backs the HomeReady® Mortgage Program, which helps lower-income borrowers qualify for homes at a fixed interest rate with just a 3% down payment, as long as they purchase private mortgage insurance (PMI) and have a credit score of at least 620.4
Freddie Mac
- Primarily buys mortgages from smaller banks.
- Buys up a mix of both single-family and multifamily homes, with more single-family loans as of late.5
- Backs the Home Possible® Program, which also helps lower-income borrowers with credit scores of at least 660 buy a home with a fixed interest rate for just a 3% down payment, given they purchase PMI.6
How Fannie Mae and Freddie Mac Affect Mortgages
Ultimately, these GSEs help:
- Replenish the mortgage supply in an effort to prevent demand from skyrocketing and making loans unaffordable for everyday Americans.
- Make longer loans possible, since lenders wouldn’t have to wait decades for reimbursement.
- Make refinancing loans with a secondary mortgage possible, since lenders have more cash to issue more loans.
It’s worth noting that while these GSEs operate privately, they’ve been under the broad oversight of the Federal Housing Finance Agency (FHSA) since 2008 to help guarantee they’re regulated and acting responsibly.7
Why Should Borrowers Care About Fannie Mae and Freddie Mac?
You don’t have to do anything differently if Fannie Mae or Freddie Mac buys your mortgage. Payments continue as usual. But to see whether one or the other owns your mortgage loan, you can use Fannie Mae’s or Freddie Mac’s loan lookup tools.
On a different note, these GSEs back up to 70% of the secondary mortgage market.8 So, changes in their structuring or government sponsorship could have a significant impact on the secondary mortgage market, which, in turn, can affect mortgage rates and overall affordability. For potential homebuyers in particular, the current state of—and legislation around—these GSEs can be another step to consider when buying a house.
Frequently Asked Questions

In simple terms, Freddie Mac is a massive, government-backed company that buys mortgages from smaller banks and credit unions. By buying these loans, Freddie Mac gives local banks the cash they need to offer new mortgages to other home buyers in your community.

Fannie Mae and Freddie Mac were both created by Congress to help keep the U.S. housing market affordable and stable. Neither company lends money directly to you.
