Thanks for all the advices..
I am buying from ONNI and wasnt sure how important it is for the lawyers to confirm.
I figured that there are few things to check sucH AS
*Capped Closing cost, Hidden charges, Square Footage...
just hope it won't cost me lots for nothing
You're spending $3-$400k! And you're worried about spending "lots for nothing" on having a lawyer check the contract. Why...because developers have such a great track record and low level of complaints from pro-construction purchasers.
Sorry for the harsh language, but give your head a shake, talk to a lawyer, and take NOTHING for granted.
For example, a 2014 completion date? (or whatever) Don't believe it - it will be 2016 or 2017, and there is nothing you can do.
A pretty landscaped park in the design plan right next to your 6th floor window (but it is currently a parking lot)? Don't believe it - expect that it will be another building blocking your view, and there is nothing you can do about it.
A clause prohibiting "assignments" (ie you sell the precon before it is finished). Well that means you can't sell your precon until it is finished, and you don't get back your deposit untli then . And there is nothing you can do about it.
Seriously. Do some serious reading up on all of this pronto.
Don't just blindly believe ANYTHING told to you by someone who profits off your purchse of your precon. Not the developers, not the salesperson, not your agent.
