Keya Homes Yelahanka 3BHK – what's the real all-in cost?

₹1.3 Cr for a 3BHK at Keya Homes, Yelahanka – is this really the final price? I work in real estate, but buying for myself is confusing. Builders often quote base price, then add PLC, parking, and maintenance deposits. What are the common hidden charges beyond stamp duty and registration that surprise buyers at possession? Matlab, kitna extra lag jayega total?
