Keya Homes HBR Layout: Hidden costs ki tension

Budget finalised, loan pre-approved – ab finally property dekh raha hoon. Keya Homes ka ek project HBR Layout mein pasand aaya hai. Initial price toh theek lag rahi, but yaar, yeh hidden charges ka kya scene hai? Builders kuch batate nahi, phir possession ke time pe pata chalta hai. Like, PLC, OC charges, utilities, yeh sab kitna add ho jaata hai total cost mein? Koi bata sakta hai ki negotiation se kitna kam karwa sakte hain? Matlab, 5-10% possible hai kya? Bahut sun raha hoon ki Bangalore mein negotiation mushkil hai.
