A $900,000 home in Irvine needs a mortgage of $720,000 at 20% down. That's below the $1,249,125 conforming limit for Orange County, so it qualifies as a conforming loan. The same $900,000 home in a baseline county like Riverside needs the same $720,000 mortgage, but the conforming limit there is $832,750. Still conforming. Now price that home at $1.1M, put 10% down, and you're borrowing $990,000. In Orange County, still conforming. In Riverside, that's a jumbo loan. Same borrower, same credit, different county, different loan category.
A jumbo loan is any mortgage that exceeds the conforming loan limit for the county where the property sits. Fannie Mae and Freddie Mac won't buy these loans, so lenders hold them on their own books or sell them to private investors. That distinction used to mean significantly higher rates. It doesn't anymore.
The Rate Myth
For years, jumbo loans carried a rate premium of 0.25-0.50% above conforming. Borrowers assumed paying more was the cost of borrowing more. That relationship has flipped. In early 2026, well-qualified jumbo borrowers are seeing rates at or slightly below conforming on many programs. A borrower with a 760 FICO, 25% down, and strong reserves might lock a jumbo rate 0.125% lower than the equivalent conforming rate.
Why? Jumbo borrowers tend to have excellent credit, significant assets, and low default rates. Lenders compete aggressively for these borrowers because the loans perform well. Banks in particular like holding jumbo loans on their balance sheets because the borrower profile fits their risk appetite.
The rate advantage disappears quickly for weaker profiles. Below 720 FICO or above 80% LTV, jumbo pricing gets noticeably worse than conforming. The "jumbo loans are cheaper" story only applies to borrowers who bring strong credentials.
What Qualification Actually Requires
Jumbo underwriting is tighter than conforming because there's no government backstop. The lender bears all the risk, so they set higher bars.
| Requirement | Jumbo | Conforming |
|---|---|---|
| Credit score | 700+ (680 minimum at some lenders) | 620+ |
| Down payment | 10-20% typical | 3-5% minimum |
| DTI ratio | 43% max (some allow 45%) | 45-50% with compensating factors |
| Reserves | 6-12 months PITIA | 0-2 months typical |
| Appraisal | Often two appraisals required | One standard appraisal |
Reserves are the requirement that catches most jumbo borrowers off guard. On a $6,000 monthly PITIA, 12 months of reserves means $72,000 in liquid assets after closing. That's on top of the down payment and closing costs. A buyer putting 20% down on a $1.2M home needs $240,000 for the down payment, roughly $15,000 in closing costs, and $72,000 in reserves. That's $327,000 in liquid capital. Retirement accounts sometimes count toward reserves, but usually at a discounted value.
The appraisal is the other gatekepper. Many jumbo programs require two independent appraisals, especially above $1.5M. If the appraisals come in low, the lender uses the lower value. In appreciating markets this rarely causes problems. In flat or declining markets, a low appraisal can kill a deal or force a renegotiation.
2026 Conforming Loan Limits
The line between conforming and jumbo moves every year. For 2026, the baseline conforming limit is $832,750. In high-cost areas, which includes most of coastal California, limits run higher.
| County | 2026 Conforming Limit |
|---|---|
| Los Angeles | $1,249,125 |
| Orange | $1,249,125 |
| San Francisco | $1,249,125 |
| San Diego | $1,006,250 |
| Riverside | $832,750 |
| Sacramento | $832,750 |
In Los Angeles and Orange County, you don't hit jumbo territory until borrowing above $1,249,125. That covers a $1.56M purchase at 20% down. In Riverside, the threshold is $832,750, which means a $1.04M purchase at 20% down crosses into jumbo. The county your property sits in determines which side of the line you're on, and the qualification requirements change accordingly.
When Jumbo Makes Sense (and When It Doesn't)
If you're buying a $950,000 home in a high-cost county with a $1,249,125 limit, you don't need a jumbo loan at all. Put 20% down and the $760,000 mortgage fits comfortably under the conforming limit with better qualification flexibility.
Jumbo becomes necessary when the purchase price pushes the loan amount above the county limit. In California, that most commonly happens in coastal markets for properties above $1.5M, and in inland markets for properties above $1.0M.
The borrower profile that gets the best jumbo terms is straightforward: 740+ FICO, 20-25% down, DTI under 40%, and 12 months of liquid reserves. That profile gets rate parity with conforming or better. A borrower at 700 FICO with 10% down and minimal reserves can still get a jumbo loan, but the rate premium, higher reserves requirement, and potential for two appraisals make the process more demanding.
One structural advantage jumbo loans have over conforming: no loan-level price adjustments (LLPAs) in most cases. Conforming loans charge LLPAs based on credit score, LTV, property type, and other factors. These add-ons can push the effective rate 0.5-1.0% above the base rate for borrowers with moderate credit or higher LTVs. Jumbo lenders typically quote an all-in rate without stacking adjustments, which makes the comparison more favorable than the base rate suggests.
Getting the Best Jumbo Rate
The biggest variable in jumbo pricing isn't the market. It's the lender. Unlike conforming loans, which are largely standardized by Fannie and Freddie guidelines, jumbo programs vary significantly from lender to lender. One bank might offer 6.25% with 12 months reserves required. Another might quote 6.50% but only need 6 months reserves. A third might beat both on rate but require two appraisals and a 720 minimum score.
