I’m Michael DiVita — DRE #01372066 | NMLS #241655, DiVita Home Finance (DRE #01818285 | NMLS #323700), Tiburon, CA. I’ve been in California mortgage lending since 2000 and founded DiVita Home Finance in 2007. I live and work in Tiburon — Marin County is my market, from hillside cottages in Fairfax to $6M waterfront estates in Belvedere, and everything in between. Call (800) 239-1103.
Marin County Home Prices and What They Mean for Financing
The majority of Marin County home purchases require jumbo financing. The 2026 conforming loan limit for Marin County — a designated high-cost area — is $1,249,125. Any loan above that amount requires jumbo underwriting, with stricter credit requirements, higher reserve requirements, and lender-specific guidelines rather than Fannie Mae/Freddie Mac standards. In Tiburon, Belvedere, Ross, and Mill Valley, where median prices routinely exceed $2M–$3M+, virtually all transactions involve jumbo or super-jumbo financing. In more accessible Marin markets like Novato, San Rafael, and Fairfax, some buyers can structure transactions within the high-balance conforming limit.
Jumbo Loan Requirements in Marin County
Portfolio jumbo lenders who serve Marin County typically require a minimum 680–720 credit score, with the best pricing reserved for scores above 740. Down payment requirements range from 10% (with higher rates) to 20%+ for the most competitive rates and terms. Debt-to-income ratios are generally capped at 43%–45%, though some lenders extend to 49% with compensating factors. Post-closing reserves are a significant requirement — most jumbo lenders want to see 12–24 months of mortgage payments in liquid assets after closing. For a $2M Marin home with a $1.6M loan, that means $50,000–$100,000 in verified liquid reserves beyond the down payment and closing costs.
Self-Employed Buyers in Marin County
A large percentage of Marin County buyers are self-employed — business owners, consultants, executives with equity compensation, and professionals in the Bay Area tech and finance sectors. These borrowers frequently face challenges with conventional income documentation because their tax returns show lower taxable income after legitimate business deductions. Bank statement loan programs — which qualify borrowers based on 12–24 months of bank deposits rather than tax returns — have become a primary tool for Marin’s self-employed buyer population. Non-QM jumbo programs that combine bank statement income with jumbo loan amounts are available from specialty lenders and typically price 0.5%–1% above conventional jumbo rates.
RSU and Stock Income in Marin County
Many Marin buyers are senior tech employees at companies like Google, Salesforce, Apple, or Meta with significant RSU vesting schedules. Some lenders accept 1 year of RSU history (vs. the standard 2-year requirement), which is critical for buyers who are earlier in their vesting cycle. When structured correctly, RSU income can dramatically increase qualifying income and open up significantly larger loan amounts. This is an area where lender selection matters enormously — not every lender handles RSU income the same way.
Why Marin Buyers Work With a Broker, Not a Bank
The diversity of Marin County buyers — in terms of income structure, asset profiles, and transaction complexity — makes broker access to multiple lenders essential. A retail bank can only approve or decline based on their own guidelines. A broker with access to 40+ jumbo portfolio lenders can find the lender whose underwriting box best fits a specific buyer’s profile. This is particularly valuable for buyers with RSU income, stock concentrations, business ownership, rental property cash flows, or other income sources that different lenders treat differently. Additionally, Marin County listing agents pay attention to lender reputation — a financing letter from a local Tiburon broker known in the market carries more weight than an online lender’s pre-approval letter.
Marin County Mortgage FAQs
What is the jumbo loan limit in Marin County in 2026?
The 2026 conforming loan limit in Marin County is $1,249,125 — the California high-cost ceiling. Loans above this amount are considered jumbo and fall outside Fannie Mae/Freddie Mac guidelines. Most Marin County home purchases, particularly in Tiburon, Belvedere, Mill Valley, and Ross, require jumbo financing given the region’s median home prices above $2M.
Can self-employed buyers get a jumbo loan in Marin County?
Yes. Self-employed buyers in Marin County routinely qualify using bank statement loans — 12 or 24 months of personal or business deposits used in place of tax returns. Non-QM jumbo programs combine bank statement income documentation with loan amounts from $1.249M to $5M+. DiVita Home Finance specializes in this structure for Bay Area business owners and executives.
How much do I need in reserves for a Marin County jumbo loan?
Most jumbo lenders require 12–24 months of PITI (principal, interest, taxes, insurance) in liquid reserves after closing. For a $1.6M loan on a Marin County home, that typically means $50,000–$100,000 in verified post-closing liquid assets on top of the down payment and closing costs. Retirement accounts and brokerage accounts generally count toward reserves (with a 60%–70% haircut on pre-tax accounts).
