Buyer financing is already restricted

Your block has 48 years of lease left. Buyers already face CPF usage limits and lower loan quantum when purchasing. This means fewer buyers qualify, and those who do will negotiate harder. Selling sooner gives you a larger buyer pool and a stronger sale price.

A specialist agent can target the right buyers and negotiate the best possible outcome for you.
