Nothing to suggest that there is a dip or a recession. All in all, it looks quite good from what I see.
I won't be so sure if I were you. From propertyguru website, the Sail has 1111 total units, yet there are 500+ units listed for sale and 600+ units listed for rent. Granted they may be double or triple posted, but the real number of units are still significant.
My guess is that the actual transactions are by the ultra-rich people looking to park their money and not real investors looking for returns. The risk of buying a unit and not being able to rent out is too high for normal investor.
