Builders always hide issues until possession.

Okay I'll be honest — I completely underestimated how confusing this process is. Rajkot mein Ansal Aastha Mig Zone mein ek flat book kiya hai, possession next month hai. Builder keh raha hai sab final checks ho gaye hain. Par I've heard ki log jab shift karte hain tab bohot issues nikalte hain, like minor cracks ya fittings ki problem. Meri parents bolte hain yeh sab common hai, but I'm nervous. Kya pehle se koi detailed snag list banani chahiye? Aur elevator quality aur uska maintenance response time kaisa hai wahan? Am I overthinking this?
