Read the bifurcation

Boston's broad Class A index reads 19.5% vacancy and trends flat. That headline masks a real bifurcation — trophy product (Financial District) is structurally tight; older Class A and Class B carry the long tail. Cycle decisions should be made at the submarket and tier level, not at the headline.

Time your decision
