currently:
1. parc life
2. visionaire
3. wandervale (cheap and big but its cck)
4. brownstone (2 bedroom)
From your choices, I can deduce that your preference is in the North area. There are some developments to look forward to apart from the Canberra MRT and sports hub. Accessibility will be much improved as well.
Personally, PL and V are on par with each other. For convenience, I will leave out Brownstone as many good units have been snapped up. Obviously, each EC developer needs to differentiate their product from the rest. So let's look at the highlights:
Visionaire - Samsung Smart Home, near future sports hub
ParcLife - next to Canberra park, 8 spas
Between developers, FCL gives a better sense of security compared to QJ due to the latter's poor publicity in previously projects. But all developments will have some defects.
Location can be argued both ways. Both are walkable to their respective MRT stations and their attached shopping centres. But let's look at other facts of location within 500m radius:
PL - next to park, near commercial buildings, chinese temple site earmarked nearby, community club, secondary school
V - opp sports hub, in the centre of 3 shopping centres (SSC, Sun Plaza, Canberra plaza), in a new neighbourhood (Canberra) within a private home cluster
It is difficult to predict how much the properties can rise in value, but generally ECs are for residential stay and long-term investment, usually a no-lose situation. With the number of condo units in the area, rental income may be a problem, but selling for a profit should be less of an issue.
There are so many potential issues that can make or break your choice, so look at your priorities. Sometimes, it can simply be down to feeling - e.g. I prefer the bathrooms of V over PL, but the general finishing quality as seen from the showflat is less stellar.
Gather lots of information and do your research if you can wait. If you can't wait so long, look at all the showflats on the same day and get a good feel, then research on the aspects that are important to you.
Good luck!
