What Is a Jumbo Loan?
A jumbo loan is a mortgage that exceeds the high-conforming limits established by the Federal Housing Finance Agency (FHFA). In San Diego County — classified as a high-cost area — the 2026 baseline conforming limit is $1,104,000 for a single-family home, and the conforming high-balance ceiling is $1,209,750. While loans between these two figures are handled under conforming high-balance programs, any mortgage above $1,209,750 requires true jumbo financing.
Because jumbo loans aren't eligible for purchase by Fannie Mae or Freddie Mac, they carry different underwriting standards. However, with San Diego's median home price pushing toward $900,000 and many desirable neighborhoods priced well above $1M, jumbo loans are essential for buyers in La Jolla, Del Mar, Rancho Santa Fe, Coronado, and other premium markets.
Despite the perception that jumbo loans are more expensive, today's market often tells a different story. In 2026, jumbo rates are frequently comparable to or even lower than conforming rates for well-qualified borrowers. Portfolio lenders — institutions that hold jumbo loans on their own books rather than selling them — can offer flexible terms, competitive pricing, and faster approvals because they set their own underwriting guidelines.
As an independent mortgage broker, Cascada Mortgage Advisors has access to over 50 wholesale lenders, including national banks, credit unions, and specialty portfolio lenders. This means we can shop the entire jumbo market on your behalf, finding rates and programs that a single bank simply cannot match. Whether you're a W-2 executive, a self-employed business owner, or a real estate investor, we have jumbo solutions tailored to your financial profile.

|---|---|---|---|---|
| Initial Rate | Higher | Lowest | Low | Moderate |
| Rate Lock Period | 30 years | 5 years | 7 years | 10 years |
