Just sharing my friends story.
Last year, before the SG govt's cooling measures and all the hype about Iskandar, he placed a deposit for one of the developements in JB. Problem was it was and still is, a bumi unit. His price was RM650 psf. That was more than 6 months ago. he was told that to convert a bumi lot takes time for approval.
So now that the mkt is so hot, and if the developer decides to play punk, i.e. tell him that conversion not approved, then re-sell at higher price or if approval really didnt go through, or if approval takes forever, etc, then I think he has been screwed big time. Cos it would mean that he would have to buy now - at higher prices!
kinda pity him cos he isnt rich and isnt a flipper. he really needs the bigger space to work cos SG property is too expensive for him. guess thats the risk of buying things in Malaysia. sigh...
