I was with a client showing properties at 13th and Wabash in South Loop. Great spot featuring Zapatista, Giocco, the Jewel and the the Roosevelt Red Line stop.
You're looking at $325-$350K for a decent 1100-1300 sq/ft two bed, two bath condo with garage or outdoor parking space. These units will typically be converted loft-loft like spaces. The views from balconies looking north at downtown can be great in this spot. The full amenity, newer buildings will start at $400K minimum with parking and go up from there.
Assessments can be high here in most buildings and range from $350-450. But, for the lower $300s, you will be hard pressed to find a better location on the lake for the price; especially if you work downtown.
