I think the Clementi locale is what drawing ppl in. Mature estate, got everything you need, near parents probably. Near good schools but sadly no good primary school within 1km. Clementi rental has always been good and the tenant pool is there - Biopolis, NUS, science park (compete with normanton park and the many new condos in Clementi tho). UOL is a reputable developer too.
But if ownstay, I don’t think it will be good. Near AYE, tower 6 will receive the dust and noise. Tower 8 set further back but likely to be blocked by the future development in the adjacent plot. The top floors are going to be very expensive and the sea view is not that great imo. Non south facing units faced HDB. Would rather go for Parc clematis if ownstay. But the ship has sailed for Parc clematis, so some buyers may choose to look past these flaws and try snap a unit at a good price.
But for investors looking to rent out, I think a 2b1bath facing the entrance 5-10 floor would be good? PSF should be among the lowest for the development. Like those penrose 2 bedders facing expressway
