Rent vs Buy in San Francisco, CA
Buying in San Francisco is a high-stakes decision. The median listing price sits at $998,250, so the down payment, the rate you lock, and your time horizon move the result far more than they would in a cheaper market.
Rent runs about $2,561 a month here, which leaves San Francisco with a high price-to-rent ratio. That generally tilts the monthly math toward renting, with buying gaining only as equity and appreciation build over time.

What the numbers say
Prices sit high in San Francisco, but the 0.75% property tax rate stays comparatively light. On a $998,250 home that is about $624 a month ($7,487 a year), taking the edge off a steep carrying cost rather than removing it.
Average rent sits at $2,561 a month ($30,732 a year), the anchor for the renting side. At about 5.2% a year, appreciation in San Francisco tracks the long-run norm, so the calculator's 3 to 3.5% anchor sits close to recent local experience.
Insurance here defaults to the California statewide average of $1,300 a year, a placeholder to replace with a real quote.
Where the San Francisco rent-vs-buy math stands out
San Francisco's price-to-rent ratio is about 32.5: the $998,250 median price divided by $2,561 a month in rent over a year. That is a high ratio, signaling that renting often wins monthly while buying depends on a long hold and price growth to catch up. Think of the ratio as a quick first read. It will not settle the decision on its own, but it shows which side starts in front.
Because the ratio is high, the monthly cost of owning in San Francisco typically exceeds rent for the first several years, even before maintenance. Buying catches up only as the loan amortizes and the home appreciates, so the honest question is whether you will hold long enough for that crossover to arrive.
