Last month I said that San Francisco is now the most expensive rental housing market in the United States, beating even Manhattan; however, that doesn’t mean that it costs more to live in San Francisco than New York City. No, it is still more expensive to live in New York City than San Francisco. That is because even though rent is slightly higher in San Francisco, the cost of nearly everything else is higher in New York City. For example, a t-bone steak at D’Agostino’s, one of Manhattan’s biggest supermarket chains, costs $18 a pound. At Safeway in San Francisco, the same steak costs $10 a pound.
