How to Buy a Home in Marin County: Step-by-Step Financing Guide

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 in Tiburon and have been financing Marin County purchases for nearly 20 years — from first-time buyers stretching to reach Novato to families upgrading into Mill Valley to clients buying waterfront in Belvedere.

Step 1: Get Fully Pre-Approved Before You Look

In Marin County’s market, showing up without pre-approval is not an option. Listing agents will not schedule showings without evidence of financing, and sellers will not entertain offers without a credible approval letter. More importantly, a standard pre-approval isn’t enough — in Marin’s competitive environment, buyers who arrive with a fully underwritten approval (where income, assets, and credit have been verified by an actual underwriter before a property is identified) are significantly stronger than buyers with a generic pre-approval letter.

Get your financial documents organized before you contact a broker: two years of tax returns, two months of bank statements (all pages), one month of pay stubs, and your driver’s license. For jumbo purchases, add a current investment account statement showing your down payment plus reserves. The pre-approval process takes 3–7 business days for a full underwrite.

Step 2: Understand Marin’s Price Tiers

Marin County’s housing market is segmented. Knowing which tier you’re targeting helps your broker structure the right loan product — conforming ($832,750), high-balance conforming ($1,249,125), or jumbo — before you begin shopping.

Step 3: Choose the Right Loan Structure

For purchases at or below $1,249,125, Marin County’s 2026 high-balance conforming limit lets you use Fannie Mae or Freddie Mac guidelines — which typically offer the best rates. Above that, you’re in jumbo territory. Jumbo loans in Marin require stronger qualifying: typically 720+ credit, 20% down, and 12+ months reserves after closing.

For self-employed buyers — common in Marin — bank statement programs allow income to be documented using 12–24 months of deposits rather than tax returns. Many Marin professionals significantly reduce their taxable income through business deductions, making bank statement qualification the better path.

Step 4: Making a Competitive Offer

Well-priced Marin County homes typically receive multiple offers within 7–14 days of listing. To compete effectively:

• Have your pre-approval letter ready before you find a home, not after
• Know your maximum number before you write the offer
• Discuss contingency structure with your agent and broker — the financing contingency timeline and whether to waive the appraisal contingency (risky but sometimes necessary to compete)
• In competitive Marin situations, earnest money deposits of 2%–3% of purchase price (on a $2M home, $40,000–$60,000) are common — have these funds pre-positioned and accessible

Step 5: Navigating Marin-Specific Property Issues

Marin’s inventory includes property types that require specific loan structures — and a broker unfamiliar with these can create last-minute complications:

• Septic-system properties: Common in unincorporated Marin; require septic inspection certification before most lenders will close
• Fire Hazard Severity Zone homes: High-FHSZ and Very High-FHSZ designations in Mill Valley, Fairfax, and unincorporated areas require homeowner’s insurance that has become extremely difficult to obtain in 2026 — secure a committed policy before making an offer
• Trust vesting: Many Marin buyers hold title in revocable living trusts — confirm your lender can accommodate trust vesting (most jumbo lenders can; some online lenders cannot)
• Non-warrantable condos: Some Marin condominium complexes with high investor concentrations or pending litigation don’t qualify for conventional financing — portfolio or jumbo lenders are the solution
