Luxury Homes Noida Extension: Is this price hike justified?

Spent the whole Sunday checking out options in the Luxury Homes corridor in Noida Extension. Honestly, kids have moved out, so don't need such a big place anymore. Looking for something manageable, good society. But yaar, Luxury Homes mein prices kafi badh gaye hain, seems like. Everyone glorifies the ROI, but I think current prices are totally inflated. Is it even worth buying now, ya wait karna chahiye? Lagta hai bubble hai. Change my mind.
