Read the bifurcation

Seoul's broad Class A index reads 5.2% vacancy and trends rising. That headline masks a real bifurcation — trophy product (Jongno / Gwanghwamun (CBD)) 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
