I moving about 4 blocks from where I live now. I still have to sell the house i'm in but I will have the new house paid for by may.
As for the southside, it's getting more expensive here. They are always building. But I see rental signs around. One really bad thing is parking. Parking on the southside really really sucks. Especially at night. Your best bet is to check the post-gazette or a real estate agent, of course you could always drive around looking for signs.
