Put 20% down on a $1.1 million home and the mortgage is $880,000. In Orange County, that amount sits below the 2026 one-unit conforming limit of $1,249,125. In Riverside County, it is above the $832,750 limit, so the loan is jumbo. Same home price. Same borrower. Different county.
That example is the real jumbo loan vs conventional loan decision. The loan amount and county determine the category. Your credit, income, down payment, and reserves determine whether the terms make sense.
Is a Jumbo Loan a Conventional Loan?
Usually, yes. A conventional mortgage is any home loan that is not insured or guaranteed by FHA, VA, or USDA. Conventional loans split into two groups: conforming loans that fit Fannie Mae or Freddie Mac rules, and non-conforming loans that do not. A jumbo loan is the most common non-conforming conventional mortgage.
For a useful comparison, put a conforming conventional loan next to a non-conforming jumbo loan.
What people call an FHA jumbo loan or FHA jumbo mortgage is usually an FHA high-balance loan. It exceeds FHA’s baseline limit but stays within the higher county limit, so it still follows FHA rules and carries FHA mortgage insurance.
The County Limit Changes the Answer
For 2026, the one-unit conforming limit is $832,750 in most U.S. counties and as high as $1,249,125 in designated high-cost areas. FHFA updates those limits each year. Two- to four-unit properties have different limits.
The listing price does not decide whether a loan is jumbo. The mortgage amount does. A $1.2 million purchase with $400,000 down produces an $800,000 loan, which is conforming in every county in the continental U.S. A $950,000 purchase with 10% down produces an $855,000 loan, which is jumbo in a baseline county but conforming in many high-cost counties.
