Are u an agent? Because agent likes to pick the most expensive rental rate that probably nobody will pay for. 

The owner also prepared to give a huge discount too.

How you estimate I could able to know estimate the actual figure? asking all the Owners 1 by 1? 

Just a Personal prediction la

650 per sqft is low floor side facing carpark bro...

if developer can sell at higher to the public, they won't sell cheaper to the closed group la..

thanks for sharing. i totally agree with these points. even being given a good deal on hand, i would think through this also and really look at the benefits of the project if i were to buy into it, instead of looking at "how nice" the project is.... i came across quite some not very good/relevant questions when it comes to investors approaching me before deciding to buy a property - mostly too focused on aesthetic instead of the strength , developer reputation and track record, the package (discount vs rebate ) , potential returns, growth triggers in the area ( the more the better, this is important especially when comparing between projects ) , supply and demand, and of course loan eligibility.
