Fannie Mae and Freddie Mac don't lend to you. Both buy conventional loans from lenders, both follow the same FHFA conforming loan limits, and both have been in FHFA conservatorship since 2008. The real differences are in each company's rulebook, underwriting system, and specialty products. On a given file, one set of rules can suit your situation better than the other. Your lender usually decides where the loan goes, so ask them to check both.
Who this may fit
Buyers and homeowners who've heard "Fannie" or "Freddie" from a lender or servicer and want to know whether it changes anything. It's especially relevant if your file has something unusual: limited down payment, non-traditional income, a condo or multi-unit property, or an underwriting result that came back with conditions.
Key decision factors
- Whether your lender can deliver loans to both companies, or only one
- How each automated underwriting system (DU or LPA) evaluates your whole file
- Eligibility for HomeReady (Fannie Mae) or Home Possible (Freddie Mac) if your down payment is small
- Property-specific rules such as condo project review or multi-unit requirements
- How income, assets, and reserves are documented under each guide
- Lender overlays, which can be stricter than either company's own rules
Illustrative example
Common mistakes
- Thinking you apply to Fannie Mae or Freddie Mac directly
- Assuming one company always has lower costs or easier approval
- Assuming the two guides are identical; a rule from one may differ in the other
- Confusing who owns your loan with who services it; your servicer may not be the owner
- Treating HomeReady and Home Possible as interchangeable without checking each one's eligibility rules
Questions to ask a licensed loan officer
- Do you sell loans to Fannie Mae, Freddie Mac, or both?
- Can you run my file through both DU and LPA?
- Would HomeReady or Home Possible apply to me, and how would they compare?
- Do you add any overlays on top of Fannie Mae or Freddie Mac rules?
- Does my property (condo, 2–4 units) need review under either company's rules?

What they have in common
Both companies were chartered by Congress to support the mortgage market. They buy loans from lenders, which frees up lenders' cash to make more loans. On September 6, 2008, FHFA placed both companies into conservatorship, and both remain under it. (FHFA, Conservatorship)
Both follow the same conforming loan limits, which FHFA publishes every year for each county. You can check yours with our county loan limit lookup. Since June 2019, both have also issued a shared security, the Uniform Mortgage-Backed Security (UMBS), so investors treat their mortgage-backed securities as interchangeable. (FHFA, Single Security Initiative)
Where they differ
Rulebooks. Fannie Mae publishes the Selling Guide (Fannie Mae Selling Guide) and Freddie Mac publishes the Seller/Servicer Guide (Freddie Mac Guide). They cover many of the same topics, but details can differ in documentation, property eligibility, and specific transaction types. Our requirements guide cites Fannie Mae sections, and Freddie Mac's rules may differ.
Underwriting systems. Lenders submit files to Fannie Mae's Desktop Underwriter or Freddie Mac's Loan Product Advisor. Each system looks at the whole file, so the same borrower can get different findings or conditions from each one.
Affordable products. Fannie Mae offers HomeReady and Freddie Mac offers Home Possible. (Freddie Mac, Home Possible) Both are meant for lower-down-payment borrowers and can have income limits that vary by area. Each has its own rules and they can change, so ask a lender to confirm the current terms for both instead of relying on a summary. See also our down payment guide.
Does it matter which one owns my loan?
Day to day, you pay a servicer, and that company may not own the loan. Which company owns your loan can matter for certain refinance or relief options that company offers. Both publish a free loan lookup tool on their websites, which you can find by searching "Fannie Mae loan lookup" or "Freddie Mac loan lookup." You can also ask your servicer. If you're thinking about refinancing, see our refinance guide.
Common questions
Is Fannie Mae or Freddie Mac better?
Neither is better for every borrower. They follow the same loan limits and serve the same role, but their rulebooks and underwriting systems can treat a specific file differently.
Can I choose between Fannie Mae and Freddie Mac?
Not directly. You choose a lender, and the lender decides where to deliver the loan. Some lenders work with both and can check your file under each.
Are Fannie Mae and Freddie Mac government agencies?
No. They are government-sponsored enterprises, and both have been in FHFA conservatorship since September 2008. Conventional loans they buy are not government-insured like FHA or VA loans.
How do I find out if Fannie Mae or Freddie Mac owns my loan?
Each company offers a free loan lookup tool on its website. Your servicer can also tell you.
