There is a co-op complex that was once military housing in my town. Two or three bedrooms. You can find units there for under $150K. They are around 700 s.f. or so, and the joke is that if you sneeze, you might get a "God bless you" from three units away.
But, it's New Jersey. Not much that cheap. I have a 940 s.f. condo for which I paid $180K.
