Post-possession construction nightmares nobody warns you about

Okay, I'll be honest — I'm completely fed up of renting and my landlord just hiked the rent again. Finally taking the plunge, planning to buy a 3BHK in Chandigarh, maybe Palm Grande Exclusive Villas. The EMI vs rent math is finally making sense. But I'm super worried about construction quality. I've heard stories about cracks, seepage, and fitting issues appearing just a year or two after possession. Is this a common reality with Palm Grande residents? What about the children's play area? Does it stay usable and safe, or does it just become a neglected checkbox item after a while? Anyone who's lived there for a bit, what's the actual day-to-day reality? Should I be worried about these long-term issues?
