Most San Francisco buyers need considerably more saved than just a down payment. Between the down payment itself, closing costs, jumbo loan reserve requirements, and a post-closing cushion, I generally tell clients to plan on somewhere between 15% and 30% of the purchase price sitting in the bank before they make an offer, depending on loan type and how competitive their target neighborhood is. On a typical San Francisco purchase, that often lands somewhere in the low-to-mid six figures.
I know that number sounds like a lot, and it is. But the buyers who run into trouble mid-transaction are almost always the ones who saved exactly enough for the down payment and nothing else. Let me walk through where the rest of that number actually comes from.
Start With What Homes Actually Cost Here
San Francisco's median home price has been sitting somewhere in the $1.3–$1.5 million range across all property types through 2026, though that figure moves depending on the data source and time of year, and it swings considerably by neighborhood and property type. Single-family homes specifically run well above that citywide median in many parts of the city, and condos typically come in lower. Before you can figure out how much to save, you need a realistic number for the type of property and neighborhood you're actually targeting, not the citywide average.
The Down Payment Isn't Fixed at 20%
A lot of buyers assume they need 20% down to buy in San Francisco, and that's simply not true. Conventional loans commonly go as low as 3–5% down, and FHA loans allow 3.5%. What does change here is the loan type you're likely working with. The 2026 conforming loan limit sits at $1,249,125 in high-cost counties like San Francisco, and given where local prices sit, a large share of purchases here exceed that threshold and require jumbo financing instead of a standard conforming loan.
That distinction matters for your savings target, because jumbo lenders typically expect a larger down payment, often in the 10–20% range, along with stronger credit and more documented reserves than a conforming loan would require.
Closing Costs Add More Than People Expect
Buyers in California typically pay somewhere between 2% and 5% of the purchase price in closing costs, covering things like the escrow fee, title insurance, loan origination fees, and prepaid property taxes and insurance. On a $1.4 million purchase, that's realistically $28,000 to $70,000 on top of your down payment, not a rounding error. I always walk clients through an actual closing cost estimate specific to their loan and purchase price well before they're ready to write an offer, because this is the number that catches people off guard the most.
Jumbo Loans Come With Their Own Reserve Requirements
If you're financing above the conforming loan limit here, which is common in San Francisco, your lender will likely want to see liquid reserves beyond your down payment and closing costs, often the equivalent of several months of mortgage payments sitting in accessible accounts after closing. This isn't money you're spending at closing, it's proof to the lender that you can weather a job change or unexpected expense without immediately falling behind. Buyers who don't plan for this get caught off guard late in the process, sometimes after they've already gone under contract.
Don't Empty the Account at Closing
Even once the down payment, closing costs, and any required reserves are covered, I encourage clients to keep a genuine cushion beyond that, generally a few months of regular living expenses. Owning a home in San Francisco comes with costs that don't show up on a closing statement: maintenance, HOA dues if applicable, and the simple reality that something in an older home will eventually need attention sooner than you'd like. Buyers who close with exactly zero dollars to spare tend to have a much harder first year of homeownership than buyers who kept a real buffer.
FAQ: Saving to Buy in San Francisco
Do I need 20% down to buy in San Francisco?
No. Conventional loans commonly allow 3–5% down and FHA loans allow 3.5%. Jumbo loans, which are common here given local prices, typically expect more, often 10–20%.
What are typical closing costs in San Francisco?
Buyers generally pay 2–5% of the purchase price in closing costs, covering escrow, title insurance, loan fees, and prepaid taxes and insurance.
Why do jumbo loans matter so much for San Francisco buyers?
The 2026 conforming loan limit is $1,249,125 in high-cost areas like San Francisco, and many local home prices exceed it, meaning jumbo financing, with its stricter down payment and reserve requirements, is common rather than rare here.
How much should I keep in savings after closing?
Beyond your down payment, closing costs, and any lender-required reserves, I generally recommend a few additional months of living expenses as a genuine cushion for maintenance and unexpected costs.
