A conforming loan is a mortgage that falls within the dollar limits and underwriting guidelines set by Fannie Mae and Freddie Mac, the two government-sponsored enterprises that buy most home loans in the United States. For 2026, the baseline conforming loan limit is $832,750 for a single-unit property in most of the country. Because these loans can be sold to Fannie Mae or Freddie Mac on the secondary market, lenders can offer them with lower interest rates and more flexible qualification standards than larger “jumbo” loans that exceed the limit.
How Conforming Loan Limits Work
The Federal Housing Finance Agency (FHFA) adjusts conforming loan limits each year based on changes in average home prices nationwide. A permanent formula established under the Housing and Economic Recovery Act of 2008 governs the calculation. Any mortgage with a balance at or below the limit can be purchased by Fannie Mae or Freddie Mac, which gives lenders confidence they can resell the loan and free up capital to make more mortgages.
In higher-cost housing markets, the ceiling is set at 150% of the baseline. For 2026, that means the maximum conforming limit reaches $1,249,125 for a one-unit property. If you’re buying in an expensive metro area, your county may fall somewhere between the baseline and that ceiling. You can look up your specific county limit on the FHFA website.
Any loan above your area’s conforming limit is classified as a jumbo loan and carries a different set of rules entirely.
Qualification Requirements
Conforming loans generally require a minimum credit score of 620. That’s significantly lower than jumbo loans, which typically require a 700 or higher. Your credit score also influences the interest rate you’ll be offered and the amount of reserves (savings) a lender may want to see.
Your debt-to-income ratio, or DTI, measures how much of your gross monthly income goes toward debt payments, including the proposed mortgage. For loans run through Fannie Mae’s automated underwriting system (called Desktop Underwriter), the maximum DTI is 50%. If your loan is underwritten manually, the standard cap drops to 36%, though it can stretch to 45% if you have a strong credit score and adequate cash reserves.
Lenders may also require cash reserves, typically up to six months of mortgage payments sitting in savings or investment accounts. The exact amount depends on your overall financial profile, the property type, and whether you own other financed properties.
Down Payment Options
One of the biggest advantages of a conforming loan is the low minimum down payment. Standard conforming mortgages allow as little as 5% down, and certain programs drop that to 3%. Fannie Mae’s HomeReady program, for example, is designed for lower-income borrowers and accepts a 3% down payment. HomeReady also allows “sweat equity,” meaning the value of renovation work you do yourself, to count toward your down payment without requiring a separate personal funds contribution.
If you put down less than 20%, you’ll need to pay private mortgage insurance (PMI), which protects the lender if you default. PMI adds to your monthly payment but can be removed once you reach 20% equity in the home, either through payments or appreciation.
How Interest Rates Compare to Jumbo Loans
Conforming loans typically carry lower interest rates than jumbo mortgages. The reason is straightforward: because lenders can sell conforming loans to Fannie Mae or Freddie Mac, they take on less risk and pass that savings along to borrowers. Jumbo loans stay on the lender’s books or are sold in a smaller, less liquid market, which increases the risk premium.
That said, the gap isn’t always large. Lenders compete aggressively for well-qualified jumbo borrowers, and in some cases jumbo rates can actually match or dip below conforming rates for borrowers with excellent credit and substantial assets. For most buyers, though, a conforming loan will offer better pricing.
Why Conforming Loans Are Easier to Get
The standardized guidelines that Fannie Mae and Freddie Mac set create a more predictable approval process. Lenders know exactly what criteria the loan needs to meet to be sellable, so the underwriting follows a well-defined path. Here’s how conforming loans stack up against jumbo loans on key requirements:
- Minimum credit score: 620 for conforming, versus 700 for most jumbo lenders
- Minimum down payment: 3% to 5% for conforming, versus 20% to 25% for jumbo
- Maximum DTI: Up to 50% for conforming (with automated underwriting), versus 36% to 43% for jumbo
- Cash reserves: Up to 6 months for conforming, versus up to 12 months for jumbo
These differences mean conforming loans are accessible to a much wider range of borrowers. A first-time buyer with a 640 credit score and limited savings has a realistic shot at a conforming mortgage but would likely be turned away for a jumbo.
When a Conforming Loan Doesn’t Fit
If the home you want to buy pushes the loan amount above your area’s conforming limit, you have a few options. The most common is a jumbo loan, which works fine but requires stronger finances. Another approach is to make a larger down payment to bring the loan balance under the conforming threshold. On a home priced just above the limit, an extra few thousand dollars down could save you meaningfully on your interest rate and qualification flexibility over the life of the loan.
Conforming loans also apply only to residential properties with one to four units. Investment properties and second homes can qualify, but they come with higher down payment requirements and tighter credit standards than a primary residence. Commercial properties and loans for land purchases fall outside the conforming framework entirely.
