Manesar property prices are totally over-inflated

Manesar – checking out 3BHKs here, upgrading from my 2BHK. Property prices seem totally over-inflated. Is this premium really justified for new projects? What's the resale value scene in 3-5 years? Not sure if future infra like DMIC justifies such a jump. Already have a home loan, need genuine opinions. Kya lagta hai?
