That's to the east of highway 680; definitely not the fortress, although prices in that area did get bid very high in 2006. Zillow lists recent nearby sales in the $300k to $400k range, an average for the zip code of $330k, and an average of the Alum Rock area of $300k.
I was going to say something clever and laugh at the notion that this is supposed to be the fortress but I'm honestly starting
to feel bad for you guys waiting for the million dollar houses to go for 400k.
I'm pulling for you but I think some may end up disappointed. Maybe buy a cheap house to rent out in Alum Rock so if prices do go up at least you wont be left empty handed.
