Proposition 13 fixes the tax base at purchase price with annual increases capped at 2%. Long-held properties pay far less than new buyers on comparable homes.
KEY INSIGHT
SF’s extreme price-to-rent ratio means renting + investing wins for most holding periods under 10 years. The $240K down payment opportunity cost is enormous. Prop 13 provides long-term tax advantage, but only for those who hold 10+ years.

Market Overview

San Francisco’s median home price of $1.2M and condos at $950K represent the highest entry point in this report series. Zillow's ZHVI for the San Francisco, CA metro reads $1.14M in the July 2026 release, so the $1.2M median stands. Over the five years to 2026Q2 the FHFA all-transactions index for the San Francisco–San Mateo–Redwood City MSAD compounded at 3.3% a year — up from the 1.5% this report previously carried, but still well below the historical norm, reflecting post-pandemic tech migration and remote work adoption. The trailing twelve months are flat to slightly negative (−0.3%), so the five-year rate is doing all the work. California’s top income tax rate of 13.3% is the highest in the nation, affecting both affordability and investment return calculations.

Price-to-Rent Ratio

The price-to-rent ratio in San Francisco is among the most extreme in the U.S. At current prices, a buyer paying $7,100–$7,900/mo in PITI could rent a comparable unit for $3,100–$3,900. The $3,000–$4,000 monthly surplus, invested at 7%, compounds rapidly and creates a substantial renter advantage for holding periods under 8–10 years.

Break-Even Analysis

Run through the engine at this report's stated basis (6.1% rate, 3.3% appreciation, 20% down, 8% selling costs, a 7% return for the renter and the $3,900 2BR rent as the comparable), there is no break-even at all inside thirty years. At a price-to-rent ratio of 25.6 the carrying cost plus the forgone growth on a $240,000 down payment outrun what equity and appreciation add, permanently. That is an answer rather than a missing number, and it is the honest headline for this market today. Against the cheaper $3,100 1BR rent — a price-to-rent ratio of 32.3 — the gap is wider still. California’s Prop 13 caps property tax assessment growth at 2%/yr, creating a growing advantage for long-term holders: after 15–20 years, the effective rate can drop below 0.5% of market value. That is a real advantage, but at 3.3% appreciation it is not enough to close a gap this wide — the refreshed rate narrows the seven-year shortfall from −$464K to −$315K without erasing it, so SF still turns on appreciation returning to something near its historical rate, not on patience alone. The three lines in the seven- and ten-year tables below are engine output at that basis: buyer equity is the projected home value less the loan balance less the cost of selling in that year; the renter portfolio is the buyer's entire upfront cash — down payment plus closing costs, less the renter's own move costs — invested at 7% and then fed or drained every month by the difference between the two paths' costs; and transaction and carrying costs are every dollar that never became equity, meaning closing costs, interest, property tax, insurance, maintenance and the exit fee combined.

Opportunity Cost

A $240,000 down payment at 7% annual return would grow to approximately $336,000 in 5 years and $472,000 in 10 years. This is the largest absolute opportunity cost in any market we analyze. Combined with monthly surplus investing, the renter’s portfolio can exceed the buyer’s net equity for the first 8–13 years.

Frequently Asked Questions

Is renting always better than buying in SF?+
Not always. For 10+ year holds with historical appreciation (5–6%), buying wins. But at the refreshed 3.3% five-year rate and 6.1% rates, renting + investing still dominates every scenario inside thirty years at this basis.
How does Prop 13 benefit SF buyers?+
The 2% cap on assessed value growth means your property tax bill grows slowly even as values rise. After 15–20 years, you could be paying less than half the rate a new buyer would on the same property.
Should I wait for prices to drop?+
Market timing is inherently unpredictable. DwellQ models what happens at various appreciation rates rather than predicting direction. Run scenarios at 0%, 2%, and 4% to see how timing sensitivity affects your specific situation.
How does California’s 13.3% income tax affect the analysis?+
High state income tax reduces take-home pay, making housing costs feel larger relative to income. However, it also makes the mortgage interest deduction more valuable at the state level. The net effect depends on your bracket and whether you itemize.

METHODOLOGY
DwellQ research uses a net worth comparison framework. Both paths—buying (building equity minus all ownership costs) and renting (investing the down payment plus monthly surplus)—are modeled month-by-month over the full holding period. Assumptions are documented, sensitivity-tested, and sourced from publicly available data. This is scenario analysis, not financial advice. Data sources and refresh dates →
