If you're looking to invest, I'd personally push out your search slightly to surrounding areas slightly south and west to maximize your dollars and long-term return potential. Bucktown/Wicker Park is no longer an "artist" community but is in fact a thriving area that is attracting national attention- the bar 50/50 was mentioned in GQ recently for instance for giving free booze to ex Lehman and Merrill Lynch employees.
There's too much to list about what's going on in the neighborhood. There's a good mix of people with many young families moving into the area along with younger couples and singles. Division street has seen a recent increase in new nightlife in addition to what has been there for a number of years. Transportation options are available with the Blue Line El at Division and Ashland and the Milwaukee/Damen stop. All-in-all a good location to invest in as the area continues to grow over the long term. It remains to be seen how the Alderman handles new construction and the issues associated with gentrification, specifically the impact on the artistic community.
