Delhi investors: Are we really calculating total acquisition costs?

Since January, I've been deep-diving into Delhi's property market, specifically around Block GH 8. Everyone talks base price, but the actual all-in cost with stamp duty, PLC, and parking is often 20-25% higher. I'm seeing this with Vikram Properties And Builder too, it's not just the sticker price, right? And construction-linked payment plans seem less flexible for negotiation compared to a lump sum. I feel spot discounts are often just inflated initial prices. The real ROI comes from understanding total cost of acquisition. Disagree? Tell me why.
