Palm Grande Villas: What operational realities affect long-term value?

What's the real scene with power backup at Palm Grande Exclusive Villas? I'm based in Dubai, can't do a site inspection myself, and planning an investment for rental income. For Chandigarh properties, full flat power backup kitna important hai? Also, water supply reliability ka kya haal hai, is there tanker dependency, ya municipal supply theek hai? Aur elevators ka maintenance response time kaisa hai? These operational details really affect tenant satisfaction and future resale value, right?
