No one can tell for sure what's going to happen in the future. Also, some buildings have more demand than others in the same area, therefore I wouldn't focus only in the neighborhood. My advise, buy as a long term investment in the neighborhood you really like in the building that best fits your needs.
Are you looking for investment property or a place to live? I agree with some of the statements below, in general, the harder hit areas have more growth potential. Call or email me to discuss further.
I agree with my colleagues your question is a difficult question to answer. Are you talking about single family home, two flat, or condo? Some of the hardest hit areas such a Edgewater Belmoral, Rogers Park just to name two depending on the type of property you are looking to purchase I feel have good potential.
