What surprises buyers at possession in Bengaluru?

Prestige City ka possession experience sabse tricky lagta hai. Kids toh ab move out ho gaye hain, toh humein ek manageable 2BHK chahiye. Keya Life By The Lake mein bhi interested hoon. But handover mein kya surprises aate hain? Builder sab kuch theek deta hai ya bahut issues hote hain? Old-age mein repair ka jhanjhat nahi chahiye, yaar.
