Builder ka power backup claims are mostly oversold for investors

My experience says the real picture only emerges after a year or two. For a project like Prestige City, my main concern for long-term ROI is utility reliability. Full flat power backup is a must for tenants, especially with Bengaluru's load shedding. Is it just common areas or actual full flat? Aur water supply, yaar, uska kya scene hai? Tanker dependency kitni rehti hai? These things directly hit rental yield and maintenance costs. If basics aren't solid, resale value down ho jaati hai. Any current residents or investors there, please share your ground reality. How to verify these during site visits?
