  • Bay Area, Marin, and Silicon Valley buyers
  • High-net-worth borrowers
  • Equity-heavy compensation structures
Local considerations
  • Post-close liquidity reserves
  • Wildfire insurance eligibility in some zip codes
  • Appraisal comps in low-volume neighborhoods
  • Anything above $1,209,750 in San Francisco, Marin, Alameda, or Contra Costa counties is jumbo territory.
  • Condo and TIC financing in San Francisco requires lenders comfortable with non-warrantable projects.
  • Napa and Sonoma estate properties with acreage or vineyards need portfolio lenders, not agency-adjacent jumbo desks.
Real-World Example

How a jumbo loan file runs.

Marin purchase with RSU income

A tech executive whose base salary alone would not qualify, with three years of vesting restricted stock history.

Purchase price
$2,450,000
Down payment
20%
Income structure
Base plus RSU vesting history
Reserves
12 months PITI

Two of the four lenders we shopped counted the RSU income in full. Choosing the right one was the difference between approval and decline.

San Francisco interest-only jumbo

A buyer with lumpy bonus income who wanted payment flexibility and planned to make large annual principal paydowns.

Loan amount
$1,900,000
Structure
10-year interest only
Down payment
25%
Property
Warrantable condo

Interest-only kept the required monthly payment low, with annual bonus paydowns recasting the payment down further.

Examples are illustrative composites of typical files, not offers of credit or guarantees of terms.

Documents you will need
  • Two years of tax returns, all schedules and K-1s
  • Two months of statements on every account used for down payment and reserves
  • Vesting schedules and equity award statements for RSU income
  • Year-to-date pay stubs and, for bonus income, a two-year history
