Your flat is approaching a key resale threshold

Your block has 72 years of lease left. Today, buyers can still get full CPF and bank loans — no restrictions. But once the lease drops below 65 years, buyers who purchase now will struggle to resell after their MOP. The closer you get, the smaller your buyer pool becomes.

An agent who knows this block can position your flat now, before the window narrows.
