I stayed in Phase 2A.. the very first phase. I stayed at the house quite near the guard post and main road, so it did not feel secluded.
The guards were mostly very young, some looked like teenagers... better to secure your house with grilles.
For phase 2A, the only break-in was the 2nd house from the far right corner (ie towards coffee shop)
If you know which unit i am talking about, the house is facing main road but quite far away from guard post. On the right side of Phase 2A is empty land hence it is easy to climb over the fence. It happened in the evening. The father is quite old and relaxed, he often leaves his gate and main door open, walks around outside. They have 2 daughters.. so not much manpower in the house. All these factors together made them easy target. Their house is single storey and they definitely do not appear "rich".
They just gave the robbers what they wanted and they were not harmed. They are Johorean by the way, the daughters schooling in SG.
On the other hand i park a white colored SG-plated car in the porch, but i cover the car most of the time... mine was corner unit. I suppose we were quite careful and people seemed to fear our dog (although this is no guarantee). Perhaps the robbers did not have chance hence they trailed me and attempted to rob me at coffee shop instead... not sure if they observed me at coffee shop only or from home. I am quite careful... i have a pair of binoculars. Whenever i spot an unfamiliar car parked nearby, even outside the fence, i will use my binoculars to observe.
I think the risk is always when one is careless, too relaxed, and if your unit is too secluded. I always advise people don't buy house at far corner away from visibility, don't let people know you don't have too many men in the house... and the early days when they are more contractors hanging around the development than occupants... if you can wait a few months let more people move in first.
