Buyers will face resale restrictions after MOP
Your block has 61 years of lease left. A buyer who purchases today and waits out their 5-year MOP will be selling a flat under 60 years — which means their buyers face CPF and loan limits. Savvy buyers know this. It shrinks your pool and puts downward pressure on price.
An experienced agent can help you find motivated buyers and close before this becomes a bigger factor.
