My lawyer believed that most likely the levy will increase to RM 30k but not before June.
There are 2 authorities involved. First one recommends and the second one approves. Apparently, the 30k levy is already recommended and in the hands of the approving body.
Now, this is my lawyers personal opinion - given that the levy has not been revised for a long time and the property prices have gone up significantly, the approval will most likely go through.
Also, based on her past experience in terms of how long it take for approval to go through and implemented, she is estimating June. Of course the outcome and timing may be totally different.
I can see why UEM is being a bit discrete. They do not want to cause panic and resulting flurry of enquiries. Let's just hope that they sort this out sooner than later.
