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. Over the past five years, appreciation has averaged just 1.5% annually—well below the historical norm—reflecting post-pandemic tech migration and remote work adoption. 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.
Model this scenario for San Francisco
Run a free analysis with San Francisco data pre-loaded.
Under baseline assumptions (6.1% rate, 1.5% appreciation, 8% selling costs), break-even falls in the 8–13 year range—the longest of any market in this series. 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. This makes SF a market where the math rewards patience—buyers who hold 10+ years benefit from both equity appreciation and declining real tax burden.
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 current 1.5% appreciation and 6.1% rates, renting + investing dominates for most sub-10-year scenarios.
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.

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.
