I think your question is more directed at which area will show more appreciation in value in 3 years. Would that be correct? I believe both areas will have higher home values in 3 years.
The answer all depends on the local economy of each, as well as the surrounding economy, as both areas tend to feed Silicon Valley. Both had seen rapid appreciation in the both years. With the foreclosures disappearing more and more as homes purchased and refinanced with "toxic" loans tending to disappear, I would say Gilroy will have greater appreciation just due to the fact it is closer to the job centers of Silicon Valley, and less of a commute. Plus, Gilroy was just picked by a major company which will be bringing in a lot of jobs for biofuel aircraft production. That will be interesting. - Sat Jul 9, 2011
