Ready to trade that San Francisco studio apartment for a French castle?

Zumper located a seven bedroom castle on 200 acres of land in Ringuette, Region Aquitaine, France renting for $2,925 per month and contrasted it against a current listing for a 401 square-foot studio apartment on Page Street in San Francisco's Lower Haight, which goes for $3,000 per month.

Another six bedroom castle in France is currently on the rental market for $4,940 per month and includes a pool, three acre garden and "several lawns." It's juxtaposed against a Laurel Heights three bedroom apartment on Collins Street that runs $4,995. No square footage is mentioned, and one of the bedrooms doesn't have a closet.

Meanwhile, the median rent for a one-bedroom in San Francisco was $3,530 in August, up nearly 14 percent for the year, according to an analysis of active listings by Zumper.

The city's real estate ridiculousness soars to new heights when compared to what can be rented for comparable rates elsewhere.
