Builder brochures for UC are just fiction?

Budget finalised, loan pre-approved — now stuck on which sector. My current 2BHK in Noida Extension (Greater Noida West) is getting small. Thinking of upgrading to a 3BHK, maybe even a villa, but builder brochures for under-construction projects feel like fiction. Gaurs Group ka ek project dekha tha, bolte hain 18 months, but current owners bol rahe hain 3 saal se upar ho gaye. Yeh jo ready-to-move ka premium hai, is it really justified for peace of mind, ya bas builders ka naya scam hai? Already home loan EMI chal raha hai, aur delays se dar lagta hai. Kya karein?
