Vatika The Seven Lamps: NRI rental yield puzzle?

Been tracking Gurugram property for a while, especially completed projects like Vatika The Seven Lamps. I'm based in Dubai, so site visits aren't easy. What's the real rental yield scene there? Brochure figures are one thing, but actual mil kitna raha hai? I'm worried about high investor ratios leading to lower rents. Any tips on verifying actual occupancy or rental agreements remotely before committing? Power of attorney se deal toh ho jayegi, but ground reality pata karna mushkil hai. Hope someone has done this research.
