Still looking for that perfect place with your very own private tennis court? Look no further than this 1920s era mansion, which boasts seven bedroom, 7.5 bathrooms, two kitchens, a library and yes, a private tennis court that is a rarity anywhere in San Francisco. The views (Alcatraz, the Golden Gate Bridge and sprawling Marin County) are stunning too, but maybe not as much as the original price tag. This home cost $93,000 in 1946, and the same family that has owned it ever since. Game, set, match.
