How We Closed a $2.15M Marin County Jumbo in 9 Days

I’m Michael DiVita (DRE #01372066 | NMLS #241655), owner of DiVita Home Finance (DRE #01818285 | NMLS #323700) in Tiburon, CA. I’ve been in California mortgage lending since 2000 and founded DiVita Home Finance in 2007. I’m known as a creative mortgage broker: when a bank says no, I find the lender and the loan structure that can say yes. Call (800) 239-1103.

In spring 2025, we closed a $2.15 million jumbo loan on a $2.875 million Tiburon waterfront home in 9 business days for a tech executive whose pay included RSUs. The keys were an underwritten file before the offer, a wholesale jumbo lender with a fast underwriting desk, and an appraisal ordered the day the offer was accepted. The rate also came in 0.375% below the buyers’ retail bank quote.

The Situation

A software executive and his wife had been searching for their long-term home in Marin County for more than a year. They’d been outbid several times in Tiburon and Belvedere, largely because their financing contingency kept coming in at 21 days — longer than sellers in that part of Marin wanted to accept.

When they found a four-bedroom waterfront home listed at $2.875 million, the listing agent said the sellers had two other offers and would favor the buyer who could close fastest with the fewest contingencies.

The Challenge

• Loan size: $2.15 million — far above Marin’s conforming limit, so this was a jumbo loan with the lender’s own underwriting guidelines.
• Income: W-2 salary plus restricted stock units (RSUs), with a significant part of their net worth in unvested equity. RSU income has to be documented carefully — vesting history, the forward vesting schedule and the stock’s value — and each jumbo lender treats it a little differently.
• Timeline: they asked whether we could close in 10 business days or fewer.

What We Did

• Underwrote the file before the offer. We’d refinanced this couple two years earlier, so we had a head start. We assembled tax returns, bank and brokerage statements, and the RSU vesting schedule, and submitted the full file to a wholesale jumbo lender before they wrote the offer. When the seller accepted, conditional approval was already in hand.
• Picked the lender for speed. Not every jumbo lender turns files at the same pace. We routed the loan to a wholesale lender with a dedicated jumbo underwriting desk that turns complete files in 24–48 hours.
• Ordered the appraisal the same afternoon. The appraiser was on site within 48 hours, which took the most common source of delay off the critical path.
• Managed the file daily. We stayed in daily contact with escrow, title and the lender and flagged every document need immediately, so nothing sat in anyone’s inbox.

The Outcome

The loan funded in 9 business days, three days faster than any competing offer had committed to — which decided it for the sellers. On a $2.15 million 30-year fixed loan, a rate 0.375% lower works out to roughly $520–$550 a month less in principal and interest at the rate levels of the past few years, or more than $6,000 a year.

How to Set Up a Fast Jumbo Close

A jumbo loan doesn’t have a fixed timeline. Speed depends on three things: how complete your file is before you write the offer, which lender the loan goes to, and how actively the process is managed. If you’re buying in Marin or anywhere in the Bay Area:

1. Get fully underwritten, not just pre-approved. Tax returns, two months of bank and brokerage statements, pay stubs, and — for tech compensation — your vesting schedule and equity statements.
2. Know how your lender will count RSUs and bonuses before you pick a price range. See my guide to RSU and equity compensation mortgages.
3. Line up reserves. Jumbo lenders typically want several months of payments in reserve after closing, and more on larger loans.
4. Plan the appraisal. Unique waterfront and luxury homes can take longer to appraise; order it immediately.
5. Talk with me before you write the offer so the contingency periods in the contract match what the lender can actually deliver.

Pre-underwriting costs you nothing, and in a multiple-offer situation it can be the difference between winning and losing the house.

Frequently Asked Questions

How fast can a jumbo loan close in California?

With a complete, pre-underwritten file, a responsive appraiser and the right lender, a jumbo purchase can close in about two weeks, as this one did in 9 business days. Many jumbo purchases take several weeks, mostly because of documentation gaps and appraisal scheduling.

Can RSU income be used to qualify for a jumbo loan?

Often, yes. Lenders generally look for a history of vesting and evidence that future vesting will continue, and they value the shares conservatively. Each jumbo lender’s rules differ, which is why lender selection matters.

How much do I need down for a jumbo loan in Marin?

Commonly 10%–20% on loans up to about $2 million, and often 20%–25% or more on larger loans. These buyers put about 25% down on a $2.875 million purchase.
