As of the end of May, the average price per square foot for a Hoboken condo is $533. Smaller units tend to go for slightly more per square foot than larger (big 2br & 3br) units in similar locations & condition. In Hoboken, the really nice units of any size, when priced right, sell very quickly and often at or above asking price.
Without knowing anything about the specific condo you are thinking of buying it's impossible to say what you should offer. That is where a good realtor adds value. He or she has tons of experience looking at similar properties and can better assess if the property is well priced. So, if you are not already working with a local - and I stress local - realtor why don't you go to the Trulia Voices search page and look for the top realtor in "07030" (Hoboken's zip code). Or , google "good hoboken real estate agent" and look for an agent who specialized in Hoboken condos and who is very knowledgeable in the Hoboken market.
Hoboken is a very particular area because of it's small size but urban character, easy commute to NYC and young, growing population which keeps demand for Hoboken condos high. If you'd like to see the most recent sales figures for Hoboken condos you can look at : http;//hobokenrealestatenews.com
