Do promised amenities actually deliver long-term value?

Since last year I've been checking out properties in Gurugram, mainly for investment. Investor perspective se, promised amenities ka kitna impact hota hai tenant attraction aur resale pe? I'm looking at places like Faith Ireo Savannah. Suna hai builders bahut kuch promise karte hain, but actual delivery aur usage mein bahut difference hota hai. Kya yeh expensive clubhouses aur facilities really drive premium pricing ya bas marketing hype hai? Maintenance charges bhi then seem like a waste if facilities are ghost. Also, construction quality – cracks, seepage issues after a year – kitna affect karta hai long-term value? Anyone experienced this? What's your advice on evaluating these things during site visits for long-term ROI?
