Asking such a question in a public forum like this and u'll get too many opinions and views from people with their personal biasness.
If ur buying for own stay, it really depends on whether u like the location and product or not. I've heard the presentation from Chin Hin's management on Ayanna before, I must say the layouts, design, concept and partially furnished package vs the price point is very good value for money, especially compared to the surrounding like Sunway Flora. But take cognisance that Chin Hin's recent product delivery has been very much below expectations.
On condo living, I've lived in a landed all my life and transitioned to condo living few years ago. I must say its a very good decision and I cannot imagine myself living in a landed house anymore.
If ur looking at it from an investment standpoint, then a 900k investment for a condo at that location is unlikely to bring u much capital appreciation or rental returns, unless perhaps, Chin Hin really surpasses expectations beyond what was promised (but i doubt so). Moreover, 1600 sqft will cost u a bomb for maintenance fees.
Perhaps, if FOMO is not affecting u (or ur parents), u can consider revisiting Ayanna later on when the product is close to completion so that u can have a better idea on its quality to reduce ur risk. At the same time, visit many many other properties to open up ur comparability vs Ayanna.
Good luck!
