NRI investing in Noida - need your real talk!

I'm based in Dubai and seriously thinking about investing in Noida. Can't really visit for site inspections, so relying on you guys. Looking at 2BHK flats near the Jewar airport because I'm hoping the connectivity will drive up prices. Is it worth it to invest in under-construction projects from Unnati Fortune Group right now? Heard some horror stories about possession delays. Also, confused about Noida vs Noida Extension. Noida Extension seems cheaper, but will the ROI be as good? Sector 150 looks promising, but is it already overpriced? Need to find a reliable property manager too. Any suggestions? Socha tha ki 'easy' hoga, but it's overwhelming. Doston, help karo!
