I would suggest picking a few places in that area and having a mooch around.
I quite like Acton which is not too overpriced. I suggest using a site like
primelocation for price guide and then use Loot paper (although at the
moment agencies are a bit more desperate and will negotiate).
Not sure if this link will work for you as I registered at some point.
