2839 W Arthington St - East Garfield Park (RT-4 lot): Approx. 3,000 sf on a quiet, tree-lined block-ideal for a 2-3-flat or small multi-unit build. RT-4 in Chicago is straightforward: plan on about 1 home per 1,000 sf of lot area and ~1.2 FAR (here, up to ~3 units and ~3,600 sf buildable; buyer to verify with the City). Location checks the boxes-near the Green Line, I-290, Garfield Park Conservatory, and the United Center/West Loop growth corridor-with nearby high multi-unit sales (~1 mi, last 12 months) backing the exit story: 3341 W Fulton Blvd ($707K), 2418 W Arthington St ($580K), 4139 W Gladys Ave ($510K), 3318 W Walnut St ($450K), 2819 W Jackson Blvd ($440K), 25 S Albany Ave ($435K).
