That would be a little tough to do since the townhouses/rowhomes/condos in that area are selling in the $500,000 range.
My old house around 8th and Oregon is selling for about $200k
I still think that South Philly is a prime candidate for urban renewal. The old row homes are of negligible historical values (although I'm sure they have sentimental value for you and others who lived in the nabe back in the day).
