Prestige City: Power backup and construction quality for investor ROI?

Honestly, I'm finding it tough to trust builder claims on amenities these days. Looking at Prestige City for investment, but long-term issues worry me. Construction quality ka kya scene hai after 1-2 years? Cracks, seepage issues common hain kya, especially around plumbing? From my experience, poor quality badly impacts resale value and increases maintenance costs over time, reducing ROI. Tenant attraction bhi affect hoti hai. Aur power backup ka kya? Builders often promise full flat backup but deliver only common areas. Bengaluru mein power cuts are real. Is full backup actually delivered at Prestige City, ya tenant attraction ke liye bas bolte hain? What's the reality with maintenance charges for these amenities versus actual service quality? Any investor experiences on this?
