Gurgaon lifts: A hidden cost for investors?

Honestly, I know the builder marketing spiel inside out, but buying my own investment flat in Gurgaon, like at Brahma City M Block, is making me question everything. I'm looking at future rental yield and resale, so construction quality matters. Specifically, elevators ka kya haal hai? I've heard stories about slow response times and frequent breakdowns in other projects. Does this affect tenant retention? Aur maintenance charges mein kya actual service milti hai for lifts? Is it value for money, ya bas bill badhta jaata hai?
