Greater Noida infra projects: Real value or just hype?

I'll be honest, after the kids moved out, managing this big house feels like a chore. Greater Noida mein ek compact flat dekh rahe hain, low maintenance. Jewar Airport aur FNG Expressway ka real impact kitna hai property prices pe? Kya Noida Extension ya Sector 137 mein appreciation mil sakta hai? Infra project delays ka risk kitna hai, especially for flats near upcoming corridors?
