Bricks The Big Wow: Is it really easy to exit?

What's the real resale potential for Bricks The Big Wow? I'm finally taking the plunge into property investment, fed up of renting. My landlord raised rent again, so I need to make this count. For Bricks The Big Wow, it's completed, but I'm worried about liquidity. How much has the price actually moved since launch? And what kind of rental yield can one realistically expect there? Is the secondary market active or will I be stuck with it for years if I need to exit?
