It's a place with high rental demand and the rental can actually cover the loan installment. These days you can hardly find any property that you buy it and the rental can pay for the loan installment. A plus point there.
However the trick with Sunway Mentari Court is poorly maintain and it is definitely not in good condition. I personally know an owner who is trying to let go his unit due to the poor maintainability. Another reason is he bought it in the very early days so he is making some capital gain for selling it now.
Thing for you to consider is, the property has
1. Good rental demand
2. Good rental yield
3. None or little room for capital appreciation
4. The environment might get worse and expect to pay for wear and tear.
It would be a good choice if your purpose is to increase your rental +ve cash flow. It would be a bad choice if you if are looking for capital appreciation.
