Noida Commercial Studio Apartments: Are Guaranteed Rentals Real?

Came across this video talking about guaranteed rentals for commercial studio apartments. It really got me thinking about some projects in Noida. I'm personally looking into buying something there, and the idea of a fixed income sounds great. Honestly, I'm a bit skeptical about these 'guaranteed' returns. Has anyone here invested in such schemes in Noida? What's your actual experience been like, good or bad? Just want honest feedback before I commit.
