Aero View Heights: Is power backup actually reliable?

₹90 lakh for a 2BHK in Aero View Heights feels like a big commitment, even for me. I work in real estate, but buying for my own investment means I'm scrutinizing everything, not just the brochure. Developers always promise full power backup, but what's the ground reality for Aero View Heights? Is it full flat or just common areas? And what about water supply? I've heard some projects in Delhi struggle with tanker dependency after a few years. Does anyone have real-world experience there? I'm worried about long-term maintenance costs and tenant complaints affecting my ROI. Is the construction quality solid enough to handle these utility demands without issues down the line?
