San Francisco is the series finale and the series extreme: the biggest check, the longest wait. At July 2026 figures, buying the median $1,330,000 condo takes $299,250 upfront and leaves a ten-year stay $124,799 behind renting the comparable two-bedroom, with net-worth breakeven in year 16. The median house makes that look gentle. Every figure comes from our rent vs buy calculator at dated, editable inputs.
Data last updated: July 2026. Rate anchor: Freddie Mac’s Primary Mortgage Market Survey 30-year fixed at 6.49 percent, week of July 9, 2026.
Here is the tension that makes 2026 different from every stale San Francisco take: rents just spiked. Zumper’s two-bedroom median hit $5,657 in July, up 22.4 percent in a year on the AI-boom recovery, and in this model every dollar of comparable rent works for the buyer. The spike is the only reason the condo’s breakeven sits inside two decades. It is still not enough to hand buying a normal decade, and this page shows exactly why.
What does the San Francisco market look like in mid-2026?
Running hot on both sides of the ledger. The overall median sale price reached a record $1.7 million (Redfin, March 2026, up 14.4 percent year over year, the largest jump in eight years), with the single-family median reported near $2.2 million by local brokerage data (June 2026) and condos near $1,330,000, up 24.4 percent year over year by Redfin’s measure. Supply is thin at roughly 1.1 months for houses. Rents followed the same employment wave: $5,657 for a two-bedroom per Zumper (July 11, 2026), with RentCafe’s $4,930 average (July 2, 2026) corroborating the direction at a lower level. The dossier’s price tiers matter more here than anywhere: this is a deeply tiered market where Noe Valley houses and SoMa condos are financially different cities.
Which price-to-rent ratio is actually yours?
San Francisco’s famous 30-plus ratio is real, but it belongs to the house market. Computed from this page’s own preset and dossier numbers: the overall pairing ($1.7 million median over the $4,200 citywide rent, annualized) gives 33.7, and the single-family pairing ($2.2 million over Zumper’s $5,950 house rent) gives 30.8. The condo pairing, the one this preset prices, is $1,330,000 over $5,657, which is 19.6. That is Denver’s lesson wearing a much bigger price tag: the ratio depends entirely on matching the home to the rent it would actually replace, and the tier you shop in decides which of these three numbers describes your decision. At 19.6, condo buying is arguable; at 30.8, house buying is a lifestyle purchase that the spreadsheet cannot bless.
What does a new buyer’s Prop 13 tax actually do? (The reverse of the Miami trap)
It starts clean and then falls behind the market, in the buyer’s favor. California resets your assessed value to the purchase price at sale, San Francisco’s secured rate for FY2025-26 is 1.18268325 percent (Treasurer and Tax Collector), and Proposition 13 caps assessed-value growth at 2 percent a year regardless of appreciation. So the preset charges 1.18 percent of $1,330,000, about $1,308 a month, and unlike Miami there is no hidden reset or suppressed average to correct: the sticker rate IS the new-buyer rate.
The modeling honesty this series owes you: our engine grows the tax base at the appreciation input (3 percent), but Prop 13 would cap it at 2, so the model OVERSTATES the buyer’s tax in later years, by about $8,069 across the ten-year tenure at these inputs. The approximation cuts against buying, which means the published breakevens are slightly pessimistic: the true condo crossover sits a touch earlier than year 16. We publish the direction rather than silently adjusting, because the same 2 percent cap is also the deep reason San Francisco ownership only redeems itself over long tenures: every year you hold, your tax bill falls further below what a new buyer of your unit would pay, a subsidy that compounds with patience and pays nothing to the impatient.
What does each path cost per month?
Owning costs $9,580 a month in cash at the preset, the series’ largest outlay; renting the comparable two-bedroom costs $5,672 with renters insurance. The stack: $6,718.21 of principal and interest on the $1,064,000 loan (6.49 percent, 30 years), $1,307.83 of property tax, $800 of building-dependent HOA dues, $200 of fire and liability insurance, and $554.17 of interior maintenance at 0.5 percent (the envelope lives in the dues). Earthquake coverage is a separate, unmodeled policy with 10 to 25 percent deductibles.
How much of the owner’s payment builds equity?
In month one, $963.74 of the $6,718.21 payment pays down the loan; $5,754.47 is interest. Add tax, dues, insurance, and upkeep and owning’s unrecoverable cost is $8,616.47 a month against the renter’s $5,672. Across year one the balance falls by $11,915 while $68,703 goes to interest, which is a year of Queens rent paid to the lender alone.
How much cash does buying take upfront?
About $299,250, the biggest entry ticket in this series: a $266,000 down payment plus $33,250 of closing costs at a plain 2.5 percent. Plain, because San Francisco’s transfer tax is seller-paid by custom and California charges no mortgage recording tax, so unlike New York there is no city-specific buyer levy hiding in the closing line. The renter investing the same $299,250 at 5 percent earns about $1,247 a month in year one, which is why the fair comparison starts the race so far in renting’s favor.
What does the seller-paid transfer tax cost at exit?
About $13,400 at the projected exit, and it is baked into this page’s 6.75 percent selling costs. San Francisco’s schedule (sf.gov) is graduated by CLIFF, not marginally: one rate applies to the entire price. Between $250,000 and $1 million it is $3.40 per $500 (0.68 percent); from $1 million to $5 million it is $3.75 per $500 (0.75 percent); at $5 million it jumps to 2.25 percent and keeps climbing. Our preset’s ten-year exit projects to $1,787,409 at 3 percent appreciation, inside the 0.75 percent tier across every scenario and the whole 15-year horizon (even the year-15 base value of $2.07 million stays far below the $5 million cliff), so selling costs are 6 percent commission-and-closing plus 0.75, or 6.75 percent. One dated proposal to watch: Mayor Lurie’s BUILD Act (introduced February 2026) would roll back rates only on $10 million-plus transactions, and it is proposed, NOT enacted, so it does not touch this page’s math.
When does buying break even?
Year 16 for the condo in the base case, with year 15 a near-tie: renting ahead by just $1,185 after fifteen years of a $943,000 cost path. The research brief estimated 12 to 15-plus years, and the engine’s 16 is consistent with that open-ended top, the closest calibration since Denver landed inside its range. At the preset’s ten-year tenure, renting finishes $124,799 ahead.
| Years in the home | Net cost of buying | Net cost of renting | Buyer's advantage |
|---|---|---|---|
| 5 | $439,115 | $278,628 | -$160,487 |
| 7 | $555,337 | $399,594 | -$155,744 |
| 10 | $716,617 | $591,817 | -$124,799 |
| 15 | $943,584 | $942,399 | -$1,185 |
What about the $2.2 million house? (The series’ most extreme number)
The single-family market is where San Francisco’s reputation is earned, and it does not need a second preset to prove it; these rows run the same engine at the house tier: $2.2 million price (local brokerage median, June 2026), Zumper’s $5,950 house rent (July 11, 2026), house-style 1 percent maintenance, no HOA, higher insurance, and the same tax and transaction inputs.
| Measure | Condo at $1,330,000 | House at $2,200,000 |
|---|---|---|
| Monthly P&I (20% down, 6.49%) | $6,718 | $11,113 |
| Verdict at a 10-year stay | Renting by $124,799 | Renting by $645,969 |
| Base-case breakeven | Year 16 | Year 32 |
| Breakeven at 4.5% appreciation | Year 7 | Year 15 |
| Price-to-rent at its own tier | 19.6 | 30.8 |
Year 32 is the longest breakeven this ten-city series has produced, past Austin’s 24 and Miami’s condo at 18. Renting the median house and investing the difference beats buying it by nearly two-thirds of a million dollars over a decade. If a San Francisco house is the goal, the honest framing is consumption plus a very long-horizon bet on appreciation, not an investment the base case supports; at 4.5 percent appreciation sustained for fifteen years, it finally works.
What rent would change the answer?
| Comparable rent | Buying breaks even | Verdict at a 10-year stay |
|---|---|---|
| $4,200 (citywide all-unit median) | Year 26 | Renting by $325,234 |
| $4,930 (RentCafe 2BR average, July 2, 2026) | Year 21 | Renting by $224,810 |
| $5,657 (preset, Zumper 2BR median) | Year 16 | Renting by $124,799 |
| $6,200 (premium-building 2BR) | Year 12 | Renting by $50,101 |
Per our series’ comparable-rent standard, the preset uses the size-matched two-bedroom median from the same citywide market as the condo median, with the vendor spread shown rather than hidden. The table’s message is double-edged: the 2026 rent spike is the buy case’s best friend, and it is also a reminder that rents here fell hard in 2020 and can again. A rent-stabilized tenant in a pre-1979 building, paying below every row, has even less reason to buy; that protection applies to many older SF units and caps annual increases at 60 percent of CPI.
What about conservative and buyer-favorable scenarios?
| Scenario | Appreciation / rent growth | Buying breaks even | Buyer's advantage at year 15 |
|---|---|---|---|
| Buyer-favorable | 4.5% / 4% | Year 7 | $514,658 |
| Base case | 3% / 3% | Year 16 (just past the window) | -$1,185 |
| Conservative | 1.5% / 2% | Not within 15 years | -$428,640 |
| Flat prices | 0% / 2% | Not within 15 years | -$701,398 |
The scenario spread here is the widest in the series: $1.2 million separates the buyer-favorable and flat-price outcomes at year 15. That is concentration risk in a single sentence, and it is the same tech-cycle exposure that whipsawed this market in 2001, 2008, and 2020. A buyer here is making a leveraged, single-asset, single-industry-adjacent bet in a way an Indianapolis buyer simply is not.
Which neighborhoods change the math?
Labeled starting points from the July 2026 research; San Francisco’s micro-markets vary sharply. Noe Valley and the Mission are single-family premium, the year-32 row’s home turf. SoMa and downtown are condo-and-HOA-heavy, rent-favorable, and where the $800-plus dues buildings cluster. The Sunset and Richmond are the relative single-family value tier. Pacific Heights is ultra-premium and above every number on this page. Bayview is the entry tier. In each case, re-run the preset with the tier’s actual price and the rent of the unit you would actually occupy.
Who should buy here, and who should keep renting?
Buying earns consideration only for a household with a fifteen-year-plus horizon, conviction about sustained appreciation, income that can absorb a tech-cycle drawdown without a forced sale, and the $299,250 entry ticket held loosely enough that concentrating it in one asset is acceptable. The condo at the AI-boom rent is the arguable case; the house is not, on the math alone. Keep renting if your horizon is under ten years (every scenario says so), if your alternative rent sits at or below the RentCafe row, if you hold a stabilized lease, or if the earthquake-plus-concentration stack would keep you up at night. And if you do buy, Prop 13 quietly rewards you for staying: the tax gap between you and the next buyer widens every year. Before committing, confirm the payment with the home affordability calculator, see the amortization in the mortgage calculator, and price the invested-cash side with the compound interest calculator.
How do you run your own numbers?
Open the rent vs buy calculator with the San Francisco preset and the July 2026 figures load, dated and fully editable. The three fields that matter most: the rent of your actual alternative (the ladder spans $1,000 a month of honest disagreement between vendors), the building’s actual HOA dues, and your appreciation conviction, which this market punishes and rewards more violently than any other in the series. For the other half of the finale pair, where the same engine meets transfer taxes on the buyer’s side instead, read New York; for the series’ other appreciation-hinged market, Seattle; for the full ten-city picture, the rent vs buy by city comparison.
Methodology, assumptions, and limitations
Every figure comes from the FinExplained calc engine, the same tested decimal-math code that powers the rent vs buy calculator, run at the San Francisco preset. The model accumulates costs year by year, credits the buyer with sale proceeds net of selling costs and the loan payoff, credits the renter with compound growth on the upfront cash, and reports the first crossover year. How we source, verify, and correct our work is on our methodology page.
What this page assumes
Purchase $1,330,000 (dossier condo median; Redfin’s fresh pulls confirm the overall $1.7M record and a 24.4 percent condo surge without publishing a fresher type-specific median) with 20 percent down at 6.49 percent for 30 years; buyer closing 2.5 percent (transfer tax is seller-paid; no mortgage recording tax in California); selling 6.75 percent including the seller-paid 0.75 percent SF transfer tax at the projected $1.79M exit (cliff schedule, sf.gov); property tax 1.18 percent of the purchase price (FY2025-26 secured rate 1.18268325 percent), with the engine growing the tax base at 3 percent where Prop 13 would cap it at 2, an approximation worth about $8,069 AGAINST buying over the tenure; HOA $800 a month, building-dependent; fire and liability insurance $2,400 a year with EARTHQUAKE coverage unmodeled; interior maintenance 0.5 percent; comparable 2BR rent $5,657 (Zumper, July 11, 2026) growing 3 percent; renters insurance $15 a month; invested cash returns 5 percent after tax; base appreciation 3 percent. All dollars are nominal, income-tax effects (including California’s high marginal rates and mortgage-interest itemization) are not modeled, and the renter’s month-to-month savings are not separately reinvested, which tilts results slightly toward buying. Market figures are point-in-time July 2026 vendor and government data, labeled by source above. Educational estimates, not financial advice.
The single most useful next step: decide your honest horizon before you look at a single listing, because in San Francisco the horizon is the verdict. Under ten years, rent and invest the $299,250; past fifteen, run your real numbers through the calculator preset and let Prop 13 start the clock.
