Noida Extension investment: Am I missing something?

I'm based in Dubai and looking at Noida Extension for investment. Novel Group projects are tempting, but the prices seem too good to be true? Sector 152 mein bhi kuch options dekhe. Rental yields advertised are like 6-7%, but is that even possible? Can't really visit for site inspections. Need a property manager, but finding a trustable one is hard. Is Noida Extension really worth it, or am I better off looking elsewhere? Has anyone else invested there recently?
