Gregoire and Christopher both grew up on the East Coast, but are now confirmed San Franciscans. Christopher is a flight attendant for a major airline, and Gregoire works in web marketing. They've been together for eight years, and when Prop 8 was finally overturned in 2013, they were among the first to get married at San Francisco City Hall. Now it's time to buy their first home together. They're willing to trade space for a downtown location in an exciting neighborhood. But is a decent apartment, even in the 500 square foot range, really in the cards in pricey San Francisco?
