Conforming Loan
A conforming loan is a mortgage that meets the size limits and underwriting guidelines set by Fannie Mae and Freddie Mac — it’s the most common type of mortgage in America, and it usually comes with the best rates and terms because lenders can easily sell these loans on the secondary market.
What Makes a Loan “Conforming”
To conform, a loan must stay within the FHFA’s annual limit — $832,750 for a single-family home in most counties (2025), up to $1,249,125 in high-cost areas. It also needs to follow Fannie/Freddie underwriting standards: maximum 45-50% DTI, minimum 620 credit score (though 680+ gets you better rates), and proper income documentation.
Once a loan conforms, the lender can sell it to Fannie or Freddie, freeing up capital to make more loans. This liquidity is what keeps conforming rates lower than jumbo or non-QM alternatives.
Dollar Example
A $400,000 conforming loan at 6.75% for 30 years costs $2,594/month in principal and interest. The same amount as a jumbo loan (hypothetically) might run 6.875-7.125%, costing $2,628-$2,694/month. Over 30 years, the conforming advantage saves $12,000-$36,000. It adds up.
Watch Out
Just because your loan amount is under the limit doesn’t mean it automatically conforms. If your DTI is too high, credit is too low, or documentation is insufficient, it won’t meet Fannie/Freddie guidelines even at a conforming loan amount. You’d need a non-QM or portfolio loan instead — at a higher rate.
Also, conforming limits change annually (they’ve gone up every year since 2017). If you’re buying near the limit, check the current year’s threshold. A loan that was jumbo last year might be conforming now. Use our mortgage calculator to model your scenario at conforming rates.
Real-World Example
You want to borrow $500,000 for a single-family home. The 2024 conforming loan limit is $766,550 in most counties, so your loan qualifies as conforming. Your lender can sell it to Fannie Mae or Freddie Mac, which means competitive rates — you lock in at 6.625%. If you needed $800,000 instead, you would cross into jumbo loan territory, likely facing a rate of 7.00% or higher, stricter DTI requirements, and a larger down payment. In high-cost areas like San Francisco or New York City, conforming limits can reach $1,149,825, so the same $800,000 loan might still qualify as conforming depending on your county.

Frequently Asked Questions
What’s the difference between conforming and conventional loans?
All conforming loans are conventional, but not all conventional loans are conforming. “Conventional” means not government-backed (not FHA, VA, or USDA). “Conforming” means it meets Fannie/Freddie limits and guidelines. A $900,000 conventional loan is non-conforming (jumbo). A $400,000 conventional loan meeting all guidelines is conforming. Compare loan types to find your best fit.
What is the conforming loan limit?
For 2024, the baseline conforming limit is $766,550 for single-family homes in most U.S. counties. High-cost areas have limits up to $1,149,825. The FHFA adjusts these limits annually based on home price changes. Alaska, Hawaii, Guam, and the U.S. Virgin Islands use the high-cost ceiling by default.
Are conforming loans the same as conventional loans?
Not exactly. All conforming loans are conventional (not government-backed), but not all conventional loans are conforming. A conventional loan that exceeds the conforming limit becomes a jumbo loan. Conforming loans follow Fannie Mae and Freddie Mac guidelines; jumbo loans follow individual lender rules.
