I would not advise you to purchase any condo right now. There is little to no appreciation to be had in the near term and a high risk of further decline, 30% decline from today's prices. You will be better off to save your money and rent for 3-5 years and be able to purchase a home for less than today's prices. Do research on risk factors by PMI or for outstanding analysis of the san diego market, an economist by the name of Rich Toscano (amusingly known as Professor Piggington

Be ware of taking any advice from sales people (i.e. Realtors) as their job is to make a comission, which means selling you a home by any means possible. They only make money when you buy your home, and the more expensive the better. Its like taking car buying advice from used car salesmen
With the economy the way it is currently, renting will give you freedom, mobility, and give you the ability to buy a home should prices fall further.
Good luck to you!
