Originally founded in 1776 by Spanish colonists, San Francisco swelled in 1849 during the Gold Rush Era. Nearly 200 years later, San Francisco is experiencing an eerily familiar, yet vastly different type of boom, where tech entrepreneurs have taken the place of gold miners. The rising cost of real estate seems nothing compared to the potential fortunes to be made by an enterprising few.

While most are familiar with San Francisco's historic architecture, cable cars and the iconic Golden Gate Bridge, these are also a few of the things that make its properties some of the most sought after in the world. With its ever shrinking inventory of available real estate, investors worldwide, particularly from China, are snatching up properties. Every inch of San Francisco is now considered a worthwhile investment for those who can afford it.
