What Is a Jumbo Loan and Do I Need One to Buy in San Diego?

What Is a Jumbo Loan?

A jumbo loan is a mortgage that exceeds the conforming loan limits set by the Federal Housing Finance Agency — the amounts that Fannie Mae and Freddie Mac can purchase. In San Diego, the conforming loan limit is substantially higher than the national baseline due to high-cost market designation. Any loan above that limit requires jumbo financing.

When Do San Diego Buyers Need a Jumbo Loan?

In San Diego's coastal communities — La Jolla, Del Mar, Coronado, Point Loma — purchase prices routinely exceed the conforming loan limit. Even with a 20 percent down payment on a $1.5 million La Jolla home, the resulting $1.2 million loan requires jumbo financing. Check the current San Diego conforming limit with your lender.

Jumbo Loan Qualifying Requirements

• Higher down payment: Typically 10 to 20 percent minimum — some programs require more
• Strong credit: Typically 700 to 720 minimum, with 740+ for the best rates
• Cash reserves: Many lenders require 6 to 12 months of mortgage payments in reserves after down payment and closing costs
• DTI: Typically capped at 43 to 45 percent for jumbo loans
• Full documentation required: Employment verification, tax returns, and assets documented thoroughly

Jumbo Loan Interest Rates

Jumbo loan interest rates in San Diego are often competitive with or slightly below conventional conforming rates for highly qualified borrowers — particularly in the current environment where lenders actively compete for well-qualified jumbo customers. This contrasts with historical norms where jumbo rates were consistently higher.
