@Sam Sav A couple things - If you are flipping, I guess HOA fees aren't much of a concern, but for buy and holds, no matter what the purchase price is, I've found the numbers usually don't work if the HOA fees are much over $200/mo. Second, I knew my balcony had structural problems at the time I bought, but it turned out every other unit in the building, none of which were showing the same signs of structural issues that may balcony was, needed to be replaced as well. So those owners got hit with a big fat special assessment they weren't expecting. Many of the buildings in Oak Lawn are getting to the age where balconies need to be replaced. For condos, this is a big ticket item - $3,000-$5,000, that needs to be considered.
As for flipping condos, I'm not sure if that is a good or bad strategy. I haven't looked that much into Chicago Ridge, but I know in the south end of Oak Lawn I haven't seen any condos selling for $80k. Usually it seems $60-65k is the max for a two bedroom. I got mine for $47,500, and after the rehab if I flipped it I would probably have lost money. But it cash flows as a rental, which is all I was looking for.
