Looks like they're selling well. From OC Register dated January 2015:
Rancho Mission Viejo?s first neighborhood, Sendero, has 125 homes left for sale of the 941 built in 11 neighborhoods. That includes the Gavilan community, an age 55-and-older enclave.
The next neighborhood will be known as Esencia, three times the size of Sendero, expected to open in the fall.
A total of 2,700 homes, plus an apartment complex, are slated to go up on 860 acres east of Sendero in a series of neighborhood terraces. Some have views of the ocean. Neighborhoods will again include plans for residents 55 and older.
Although prices and home plans aren?t yet available, the community will include a K-8 Capistrano Unified School District campus, clubhouses, parks and playgrounds and open space for hiking.
Rancho Mission Viejo was listed as the top-selling new master-planned community in the state last year.
