For those who can’t quite afford a full brownstone, here’s a chance to buy half of one. This stately State Street co-op with “19th-century charm” (check out those moldings) and 21st-century conveniences offers a balcony, a patio and a big back yard. The unit also has a full-level cellar for storage or transformation into more living space. Agent: Greg McHale, The Corcoran Group, 212-500-7018
