Location wise, it is pretty close to BART as you can click to see ... http://maps.google.com/maps?f=d&hl=en&geocode=&s
$250K for a 2 bedroom condo in Berkeley or the closest towns, Oakland, Emeryville, El Cerrito or Albany, even in this market, is a pretty tall order. $250K is closer to the 1 bedroom condo price range. It may be possible to find a larger condo closer to your price range in areas that are farther from campus, but still accessible via BART.
Remember to include the monthly Association Dues in your calculations for what you may be able to afford. This can range from $250-$400 a month more.
My office is head quartered in Berkeley. Feel free to contact me for more information.
