Sector 155 investment, Dubai se — real ground truth?

Sector 155, Noida — properties yahaan kaafi dekh raha hoon. I'm based in Dubai, so site visit karna mushkil hai. RBS Buildtech Pvt Ltd ke projects kaise hain? Their marketing looks good, but builder ka track record real mein kaisa hai? Aur from abroad, rental management kitna headache hota hai? Kya advertised rental yields sach mein milte hain?
