NRI investor's dilemma: Greater Noida insights needed

Budget finalised, loan pre-approved – ab The Park, Greater Noida mein invest karne ka soch raha hoon. Completed project hai, so possession ka issue nahi. But I'm based in Dubai, can't visit. Iska actual rental yield kaisa hai? Aur resale market kitna liquid hai? Capital appreciation ka kya scene hai, will it appreciate? Bahut confusing hai yaar.
