i live in the urban core in St. Louis. My own neighborhood is yuppified with new $500,000 houses just built across the street from where I live. But we have property nearby where we have our main gardens. Gardens are on the bad edge of a transitional neighborhood, hence the cheap price, hence that's why we can affords houses with no tenants.
well, but the lack of plumbing/ heating thing is actually a St. Louis city wide issue. Very few people know this and would be shocked to know, but even today one of the grand old houses forming our signature neighborhood look, our brand so to speak, still lacks indoor heat. The guy who stays there moves in with his girlfriend during the winter.
Here's the image everone uses about our neighborhood and the house without heat is on far right: http://tinyurl.com/pcmxqcx
