Goyal Luxury Floors: Utility reliability pe doubt hai

Budget finalized, loan pre-approved for Goyal Luxury Floors in Faridabad. I work in real estate, so I know builder promises vs reality. Investor perspective se, utility reliability crucial hai. Power backup full flat milega ya sirf common areas? Water supply reliable hai ya tanker dependency rehti hai? Elevator quality aur maintenance response time bhi tenant attraction aur resale par impact karte hain. Any off-the-record insights?
