I can say that I wouldn’t buy my apartment… not now, no way. San Diego (and especially the La Jolla / UTC area) has very high rents, too. But I’m convinced now would be a terrible time to buy a condo here. Just my opinion, though. I’m sure you’ll get many more.
But do yourself a favor and do some searches on this site (upper-right corner) about condo conversions, rent versus buy, etc. You’ll be glad you did… whatever decision you make.
