Mortgage Pre-Approval Guide for San Francisco Buyers
What a real San Francisco pre-approval looks like — jumbo limits, asset documentation, RSU and bonus income, and how listing agents actually read your letter.
Mortgage Pre-Approval Guide for San Francisco Buyers
I'm Christopher Lee, a San Francisco Realtor (DRE #02120811). I've watched dozens of offers get thrown out — not because the price was wrong, but because the pre-approval letter behind them was weak. In San Francisco, where the median single-family home trades around $1.6M and condos around $1.1M, your pre-approval is not a formality. It is the document a listing agent uses to decide whether your offer is real.
This guide is the version I wish every buyer had before they called a lender. It covers what a real SF pre-approval looks like, what to ask your lender, how jumbo loans work here, how RSUs and bonuses count, and exactly how listing agents read your letter.

What "pre-approval" actually means in San Francisco
There are three things lenders call "pre-approval" and only one of them helps you win an SF offer.
| Type | What the lender did | What it's worth in SF |
|---|---|---|
| Pre-qualification | You told them your income verbally. Soft pull or none. | Nothing. Don't show this to a listing agent. |
| Standard pre-approval | Application + credit pull + stated income/assets. | Acceptable in slower markets, weak here. |
| Fully underwritten / "TBD" approval | Underwriter has reviewed W-2s, tax returns, asset statements, RSU vesting schedule. Loan is approved subject only to property. | The version that wins in SF. |
In a competitive offer situation — anywhere on the east side of the city, Noe Valley, Bernal, Mission Dolores, Cole Valley, the Marina, Pacific Heights — listing agents read your letter looking for the words underwritten or credit-approved subject to property. If they don't see those words, they assume your file hasn't been touched by a human underwriter and your offer drops a tier in their stack.
What I tell every SF buyer to ask their lender
Before you let a lender pull credit, ask these eight questions. The answers tell you whether they actually do SF loans or whether they're going to learn on your file.
- Are you a direct lender, broker, or correspondent? Direct lenders (portfolio banks like First Republic's successors, Schwab, Bank of America Private Bank, Citi Private Client) and well-run mortgage banks can move faster on jumbos than the average retail bank.
- What's your jumbo loan limit and pricing matrix? SF is in a high-balance conforming area — the conforming limit is over a million dollars, so jumbo pricing kicks in higher than nationally.
- Will you do a full underwriting upfront ("TBD property" approval)? This is the single most important question.
- How do you treat RSUs, ISOs, and bonus income? Different banks count vested-but-unsold RSUs and recent vesting history wildly differently. See the RSU/stock comp guide.
- Do you offer pledged-asset or securities-backed lending? Schwab, Morgan Stanley, JPM Private Bank let you pledge a portion of a brokerage account instead of liquidating for down payment.
- What's your appraisal contingency waiver strategy? Local lenders who fund a lot of SF deals can often appraise quickly and know which neighborhoods are appraisal-safe.
- Can you close in 21 days? Many SF sellers expect 21–25-day closes on financed offers.
- What's the rate-lock policy if I need to switch properties? You'll likely write more than one offer before one sticks.
If a lender hedges on more than one of these, keep shopping.
Documents to have ready before you call
I tell buyers to spend a weekend gathering this. It saves two weeks later.
W-2 employees
- Two years of W-2s
- Two years of federal tax returns (all schedules)
- Most recent 30 days of pay stubs
- Two months of statements for every account holding down payment, reserves, or closing costs (every page, including blank ones)
- Driver's license
- If RSUs are part of comp: vesting schedule from Shareworks/Carta/E*TRADE, plus brokerage statements
Self-employed / 1099 / business owners
See the self-employed buyer guide — it's a different document list and a different underwrite.
Gift funds
- Signed gift letter
- Donor's bank statement showing the funds before transfer
- Wire receipt or canceled check
- Your statement showing receipt
Gift documentation is where deals get held up in underwriting. Get the gift in your account at least 60 days before you write an offer if you can — "seasoned" funds need less paperwork.
How much can you actually afford in San Francisco?
The honest answer is: less than the DTI calculator says, because SF carries costs most national calculators miss.
A realistic SF monthly cost stack on a $1.5M purchase with 20% down:
| Line item | Monthly |
|---|---|
| Principal & interest ($1.2M jumbo at current rates) | ~$7,400 |
| Property tax (~1.18% of purchase, prorated) | ~$1,475 |
| Homeowners insurance | ~$200 |
| HOA dues (condo, varies wildly) | $400–$1,500 |
| Earthquake insurance (optional, recommended) | ~$150 |
| Total carrying cost | $9,500–$10,700 |
Most SF buyers I work with comfortably qualify at a 43% DTI, but feel comfortable living at 30–35%. The gap between those two numbers is the difference between enjoying your home and resenting it.
Run your scenario in the Buying Power Calculator — it models jumbo pricing and SF property tax correctly.
Christopher's Take: The buyers who regret their purchase three years in are the ones who maxed their DTI on a teaser rate and then had their RSU comp drop. The buyers who love their home are the ones who bought 10–15% under their max and kept liquidity for assessments, repairs, and life.
Pre-approval letter: what listing agents actually read
When I'm on the listing side, I open your pre-approval letter and scan for five things, in this order:
- Loan amount and purchase price. Does it match the offer? If your letter says "up to $1.4M" and your offer is $1.6M, you look unprepared.
- Down payment source. "Verified funds on deposit" beats "to be wired from brokerage" every time.
- Underwriting status. I want to see fully underwritten, DU/LP approved with conditions, or credit-approved subject to property.
- Lender name. A name I recognize — a real bank or a local mortgage banker I've closed with — beats a national 1-800 lender.
- Loan officer's direct phone number. I call. Always. If your LO doesn't pick up or can't speak to your file in detail, that's a red flag.
Generic Rocket / online-lender letters with no contact name don't get the same trust. That's not a judgment of the lender's quality — it's a reflection of how SF listing agents make decisions in a multiple-offer scenario.
Step-by-step: the SF pre-approval timeline
Day 1–2. Choose 2–3 lenders. Request rate quotes on the same loan amount, term, and product on the same morning so you can compare. Don't share who else you're talking to.
Day 3–10. Submit a full application and documents to your chosen lender. Authorize the credit pull. Multiple mortgage pulls within a 14–45 day window count as one inquiry for FICO scoring.
Day 7–14. Underwriter reviews. Respond to conditions within 24 hours — every delay pushes your timeline.
Day 14–21. Receive a fully underwritten "TBD property" letter. This is what you walk into open houses with.
Day 21+. Each time you write an offer, your lender re-issues the letter at the specific property address and purchase price.
Cash buyers, foreign buyers, and edge cases
All-cash offers still benefit from a proof-of-funds letter that lists the exact account, balance, and date. A screenshot is fine; a formal letter from your wealth manager is better.
Foreign nationals without US credit can get financing through portfolio lenders at 30–35% down with 12 months of US-equivalent reserves. Plan extra time.
Recasting and delayed financing. If you close cash and want to put a mortgage on within 6 months, Fannie's delayed financing exception lets you pull cash back up to the original purchase price.
Common mistakes I see weekly
- Opening a credit card during the loan. Don't open or close anything from application to close. Don't even apply for an Apple Card.
- Moving money between accounts. Every transfer needs paper-trailing. Stop moving money 60 days before you apply.
- Switching jobs mid-loan. Possible but painful. If you're considering a job change, talk to your lender first.
- Ignoring the appraisal-gap conversation. In SF, properties sometimes appraise low. You need a plan: cash to cover the gap, or an appraisal contingency.
- Forgetting HOA dues count toward DTI. A $1,200 HOA can knock $200K off your buying power.
