I met a lady this weekend at the free BBQ held at San Diego BMW dealership and she kept telling me that real estate was falling for next 10 years and to buy a home in Chula Vista. When I told her that a) all the jobs are far away and b) that Chula Vista is a ghetto full of Mexicans (nothing against latinos) next to National City she argued that Del Mar, Pacific Beach and UTC were too expensive. I told her that I would wait for the market to complete its fall and buy close to work because I hate getting stuck in traffic to and from work.
Most jobs at least for IT and biotech are in UTC, North County, Sorrento Valley and Carlsbad all areas far away from Chula Vista. I value quality of life and do not really wanna drive 2 hours each way to work. That and houses are now expensive in Chula Juana anyhow.
If I stay in San Diego longer than 2 years I would buy a 2-3 bedroom place close to my job.
