Buying Beats Renting in Just 2 of 8 SF Neighborhoods

San Francisco lease renewals are arriving with bigger numbers this year, and many renters are pricing a purchase against the lease.

We priced that purchase for eight San Francisco neighborhoods, from Bayview to Noe Valley. At the September 10 mortgage rate of 6.76 percent with 20 percent down, owning the median home costs less each month than renting a citywide three-bedroom in just two of them, Bayview and Excelsior. In the other six, renting costs less month to month, by $2,946 to $12,605.

The question got louder on Thursday, when Mayor Daniel Lurie declared a rent emergency, as The San Francisco Standard reported.

What the rent emergency does, and what it leaves to the supervisors

The Standard described the declaration as largely symbolic, a signal that housing is a top priority for the administration, with limited legal power of its own.

The declaration comes with several proposals. Weekly Real Estate News, summarizing Thursday’s coverage, counts six new ordinances alongside new spending.

On evictions, Lurie backed Supervisor Jackie Fielder’s proposal to block evictions of tenants who owe less than one month’s rent. He also called for $3 million to pay lawyers representing 400 households in eviction cases, and an additional $3,000 for tenants displaced under the Ellis Act, the state law that lets owners take a building off the rental market.

On rent increases, he supports Supervisor Danny Sauter’s proposal to cap increases in rent-controlled apartments at 10 percent a year, and Supervisor Matt Dorsey’s proposal to send tenants a yearly notice of the maximum legal increase and the eviction rules.

The Standard, citing Zillow, puts the average one-bedroom at more than $4,300, up more than $1,000 from a year ago, and reports that 489 new units have been completed in the city so far this year. Apartment List’s September report has the citywide median at $3,844, up 25.6 percent year over year and 3.2 percent in August alone.

How we priced owning against renting

Every neighborhood gets the same assumptions, so the comparison holds even if your own numbers differ.

For price, we took the latest month in each neighborhood’s 12-month price history on Houseberry, which is July 2026 for some neighborhoods and August 2026 for others. The loan is 20 percent down on a 30-year fixed at 6.76 percent, Freddie Mac’s weekly average as of September 10. Property tax is San Francisco’s 1.18268325 percent secured rate for fiscal 2025-26, applied to the purchase price. We added $250 a month for homeowners insurance as a round assumption.

We left out HOA dues, maintenance, parcel taxes and any mortgage interest deduction. Dues and upkeep would raise the cost of owning, and tax savings would lower it.

On rent, credible neighborhood-level figures do not exist for most of these areas. Zumper publishes medians for about a dozen San Francisco neighborhoods, mostly downtown and on the north side, and none of the southern or western neighborhoods in our sample. So we used Zumper’s citywide asking rents as of September 9, 2026: $6,160 for a two-bedroom and $7,976 for a three-bedroom. The median home in most of these neighborhoods is a house, which makes the three-bedroom rent the closer match.

San Francisco rent vs. buy, neighborhood by neighborhood

Under these assumptions, owning and renting a three-bedroom meet at a purchase price of about $1.25 million. Below that, a mortgage can beat the lease. Above it, owning costs more every month, and the gap tops $10,000 in Potrero Hill and Noe Valley.

Bayview is the clearest case. The southeast neighborhood along Third Street and the T Third line had a July 2026 median of $869,480, which works out to about $5,623 a month, below even the $6,160 two-bedroom rent. Bayview ranks 87th of 92 on our overall score, at 2.3 out of 5, with safety at 2.4.

Excelsior, the hilly grid between Mission Street and McLaren Park, pencils too, at about $6,739 a month on a July median of $1.05 million. It scores 2.7 overall, and its median is down 7.6 percent from a year earlier.

The Outer Sunset, the fog-belt grid on the city’s west side between Golden Gate Park and Ocean Beach, is where the math turns. The Outer Sunset is tied for the top overall score (4.2) among San Francisco’s 92 neighborhoods, with a 4.5 school score, and its August median of $1.73 million costs about $10,922 a month to own. That is $2,946 more than the three-bedroom rent.

Another 25 percent rise in rent over the next year would lift that $7,976 to about $9,970, still short of the Outer Sunset payment.

Farther up the ladder the gap widens fast. Owning the median in Bernal Heights, the hill south of the Mission, or in the Inner Mission itself runs close to $15,000 a month. Noe Valley’s July median of $3.29 million costs $20,581, about 2.6 times the three-bedroom rent.

What the monthly math leaves out

The down payment is its own hurdle. Twenty percent of Bayview’s median is about $174,000, and on the citywide August median of $2.2 million it is $440,000, cash a renter would otherwise keep invested.

A single month’s median can also swing on a handful of sales. Bernal Heights jumped 11.7 percent from July to August, and Noe Valley fell 10 percent from June to July. The medians also mix condos and houses, which matters most where a neighborhood has plenty of both.

Part of each mortgage payment builds equity. In the first month of a Bayview mortgage on these terms, about $598 of the $4,516 principal and interest payment goes to principal. The citywide rent-versus-buy math we ran in June shows how rising rent shortens the payback period, and our August piece on the 23 percent rent jump covers the vacancy squeeze behind this year’s run.

Our San Francisco neighborhood rankings carry scores and a 12-month price history for all 92 neighborhoods, which is where every price in the table above came from.

For the Outer Sunset to break even with today’s $7,976 three-bedroom rent at its August median of $1.73 million, the 30-year rate would have to fall to roughly 3.3 percent, less than half of this week’s 6.76 percent average.
