The East Bay’s premium submarkets — Lamorinda (Lafayette, Moraga, Orinda), the Diablo Valley (Danville, Alamo, Walnut Creek), and parts of Piedmont and Alameda — are jumbo loan territory. With median home prices ranging from $1.4M to $4M+ in these communities, most buyers need financing well above the 2026 conforming limit of $1,209,750 for Alameda and Contra Costa counties. I’ve been placing East Bay jumbo loans since 2007. I’m Michael DiVita — DRE #01372066 | NMLS #241655, DiVita Home Finance (DRE #01818285 | NMLS #323700), Tiburon, CA. Call (800) 239-1103.

East Bay Jumbo Loan Requirements 2026

- Down payment: 10% for loans up to $2M with strong credit; 20%+ for larger amounts
- Reserves: 6–12 months of PITI after closing. In Lamorinda and Diablo Valley where PITI can exceed $10,000/month, this means $60,000–$120,000 in liquid reserves beyond your down payment
- DTI: Most programs cap at 43–45%; some allow 49% with strong compensating factors
- Income documentation: W-2, self-employed (2-year tax returns), bank statement, or asset depletion programs all available
School District Premium and Jumbo Loans
The Lamorinda corridor commands a premium specifically because of the Acalanes Union High School District — consistently one of California’s top-ranked public high school districts. This school premium is real and reflected in appraised values, which is good news for borrowers since appraisals in these communities tend to support purchase prices. Danville and Alamo similarly benefit from the San Ramon Valley Unified School District. Understanding how school district boundaries affect appraisals is something I navigate on every East Bay jumbo transaction — local knowledge matters at this price point.
Fixed vs. ARM on East Bay Jumbo Loans
On a $2M East Bay jumbo loan, a 0.75% rate difference between a 30-year fixed and a 10/1 ARM translates to approximately $1,000/month. If you expect to own the home 7–12 years — common in Lamorinda and Danville with school-age children driving your timeline — a 10/1 ARM provides full rate certainty during the period you’re most likely to stay, with significant monthly savings. I model both scenarios for every client based on their actual expected ownership period.
Self-Employed East Bay Jumbo Buyers
The East Bay’s tech and entrepreneurial community means a high proportion of self-employed buyers whose tax returns understate their income. Bank statement jumbo programs qualify on 12–24 months of deposits rather than tax returns, and are available up to $3M+ through DiVita Home Finance’s wholesale lender network. If you’re self-employed and targeting Lamorinda or Diablo Valley, call to discuss your income documentation before assuming conventional financing won’t work.
Frequently Asked Questions
What is the jumbo loan threshold in Alameda and Contra Costa counties in 2026?
The 2026 high-balance conforming loan limit for both Alameda County and Contra Costa County is $1,209,750. Any loan above this amount is a jumbo loan subject to lender-specific guidelines. Most purchases in Lamorinda (Lafayette, Moraga, Orinda), Danville, Alamo, Piedmont, and Pleasanton require jumbo financing given median home prices in these communities.
Can I get a jumbo loan with 10% down in Lamorinda or Danville?
Yes — for East Bay jumbo loans up to approximately $2M, 10% down is available from multiple wholesale lenders with 720+ credit. Above $2M, most programs require 20% down. DiVita Home Finance has placed 10% down jumbo loans in Lafayette, Orinda, and Danville. The right lender depends on your specific loan amount, credit profile, and reserves — call (800) 239-1103 to get matched with the right program for your purchase.
Why use a mortgage broker instead of a bank for an East Bay jumbo loan?
Jumbo rates vary significantly between lenders — 0.25–0.50% differences on the same day for the same loan profile are common. A mortgage broker shops 40+ lenders simultaneously and brings you wholesale pricing that retail banks don’t offer directly. For large East Bay jumbo loans where a 0.375% rate difference translates to $700–$800/month, the broker advantage is substantial. DiVita Home Finance has specialized in Bay Area jumbo loans since 2007 and brings local market knowledge alongside wholesale pricing.
