Third property in Noida — assessing payment plan leverage

Been tracking the Noida market for years now, especially after my last two investments. I'm looking at a new project by NS Promoters in Sector 21. They're pushing a Construction-Linked Payment Plan pretty hard, offering some incentives over a traditional down payment structure. From my experience, CLPs can tie up capital for too long, impacting overall ROI if construction delays hit. But a hefty upfront down payment also means higher immediate cash outflow. I'm trying to calculate the true cost of acquisition. Is it smarter to negotiate harder for a spot discount with a down payment, or leverage the CLP for better cash flow management? I've seen builders become more rigid lately. What are others seeing in terms of negotiating payment terms right now? Any hacks to get better financial terms from builders on these plans? Curious about experiences.
