normally high rise, rental is better. but PH currently no precedent for rental. cannot gauge at all.
(3) at least is near to BI.
all 3 are reasonably prestige properties. i think (2) is good value, if indeed 1.25m (still at registration of interest stage, right?). developer is good, it's a few mins drive (or walk?) to the sea side, price is reasonable.
(1) is also not bad, because it is nearer to "civilization", mall and amenities all within 5 mins drive. but is it subsale? if yes, add another 20k for stamp duty on MOT. the house is also smaller.
but really, for rental? for that money i would go for 2-3 units in BI and perling or even older condo in jb town.
meaning: if you're singaporean and cannot buy those <500k condo, you're playing a losing game in terms of rental.
really depend on what you want. holiday home is great, rental play not so.
my 2c.
