Absolutely no extra cost for boundary wall ! So the breakdown is like this, lets say you buy a 1200SqFt villa , so this is what you pay. 1. Property price = ₹ (1200 × 3200) = ₹3,840,000 2. Transformer cost = ₹35,000 (one time) 3. Registration cost = 6% of ₹3,840,000 = ₹230,400 Total cost = ₹4,105,400 @Bhabani Das
