As you probably know there aren't a lot of houses in emeryville. Some of the area s you are asking about are also partly Oakland. I rand a map over each area and this is what I found for you. Hopefully Trulia will format it so that its readable
In the past 2 years there have been 42 detached homes sold in the first area you mentioned. Here are the stats:
High low average median total
list price 549K 199K 277K 252K $13,275,405
sold price 475K 110K 268K 245K $12,841,290
Days on market 381 1 71 41
In the second area you asked about , which is a much smaller area there was only one property sold in the past two years. It was 5564 Freemont, 2 houses on one lot, sold last January for 475K, listed at 549K.
hope this helps
