Manya Elite: investor ki umeed vs ground reality?

Did a site visit to Manya Elite last week. Builder ne brochure mein bohot amenities promise kiye the, but actual site par dekh ke thoda doubt ho raha hai. Clubhouse toh almost khaali tha, hardly anyone using it. Soch raha hoon, agar amenities use hi nahi ho rahe, will it impact rental yield ya resale value? Kya sirf marketing hype hai?
