Where is the growth happening in bay area?

[Surya Kumar]

So we recently moved to bay area and live in apartment for the past year. We plan to stay here for at least 3 years and may be more. I would rent forever but with the bay area market going very strong, I think prices will appreciate still for a while. We have saved up some cash ($100k) for a small condo/town house somewhere in the bay area.   What are the areas where it is affordable with this downpayment, and secondly what are the upcoming areas that will get the most appreciation in the next 5-7 years? I am thinking of areas like Union City, Hayward, Dublin but I am finding it hard to narrow down. Any help would be welcome.
