Is all depend on individual affordability.
you don't have to wait for subsale for larger unit.
there are plenty on going and new projects out there with larger unit.

I can totally understand some may be wary due to insufficient information and the hush-hush way it is being marketed. I am too. So I did quite a fair bit of research to see is this a scam or not becoz it sounds too good to be true at first glance. From the bits and pieces of information I get shows this is a genuine project. Last Saturday at Googolplex Convention when Dato Vincent (Andaman CEO) actually appears on stage, it is the confirmation already that fits all the puzzles.

About your concern, will it be the only project sitting there on a big piece of land? IMHO, I dont think so. Why? Becoz they have already bought the land and need to service its loans. Why buy so big, every month pay interest, but not develop it? By completing first phase it wont be enough to breakeven for the purchase of the entire 88 acres also. So for sure they would need to launch the next phase, which would be a 2-3 bedroom condo units. Probably this project they would start to make profit. I have no visibility of 3rd phase yet but why go through so much trouble to make a little bit and stop at phase 2? So it makes sense to develop phase 3. The rumors I heard would be landed houses (Banglo/SemiD/Terrace).

Anyway, that would be too far to think for a 300k prop. At the current market itself, it is the cheapetest new prop sitting in Tier 1 realistically 15mins to KLCC. Yes I have actually went there to check the site and tested the travelling time. (10mins to jam down to Jln Ampang, 5 mins on AKLEH and you'll hit to KLCC parking.)  Comparing nearby undercon ones like Elements and MK Tower, this is a steal and even if market stays stagnant, upon completion, you can flip it at 950psft at least and still be cheaper than earlier completed MTower or Elements.

Not forgetting this is sitting on Selangor land and not KL land. So assessment would probably be cheaper also.

Bottom line, I think its a great deal. More importantly, it is a genuine project. The reason they cant market it openly yet is becoz they havent get the approval I supposed since the land purchase is being completed not long ago only. If you check the stock price of Ecofirst, there is a huge spike of volume in early October. Chances are it is institutional buying or huge capital injection in the form of stock purchase (Andaman or Insider).

Hence, I am fairly confident and straight away grab my unit. Some ppl didnt even do any research and grabbed a few already. Many left disappointed unable to get any last Saturday.

Hope that addresses your question.
