With the success of Thunderbird and Tamarisk Country Clubs, developers bought land nearby to build small resort-style neighborhoods of homes and apartments. From the mid 1950s onwards, these offered a lower-cost, maintenance-free alternative to a big home on the fairways, yet every community advertised that it was near Thunderbird and Tamarisk, such was the allure of the clubs. The other attractions to the new developments were the central facilities, such as a pool and gardens, often a social center, and other services. By the mid-1960s the condominium concept had taken root, so that owning a second home was easily affordable and available. As Rancho Mirage was incorporating as a city in 1973, it was also becoming the center for the expanded country club model that came to epitomize its profile, such as Mission Hills, Desert Island, Sunrise and the Springs.
