Under-construction flats are giving me anxiety!

Okay I'll be honest — I'm selling my big house now that the kids have moved out. Looking at smaller flats in Noida, maybe sector 96. Vatsalaya looks good, but under-construction scares me after hearing so many horror stories. Is it worth the risk for slightly lower prices? Ready-to-move seems safer, right? Kya kisi ko pata hai?
