Noida Extension: Payment plans are confusing me as an investor

Since January, I've been eyeing properties in Noida Extension, especially around Chamrawali Bodaki. I work in real estate but buying for myself is a whole different ball game, yaar. Builders like AMR Infrastructures offer both construction-linked (CLP) and down payment (DP) plans. For a 2BHK around 80L-1.2Cr, I'm trying to figure out which is smarter for an investor. CLP feels safe from delays, but DP might get a better price, right? Also, secondary market mein kya negotiation scope zyada hota hai compared to new projects? What's your experience with maximizing ROI – CLP ya DP? Aur resale mein kitna discount mil sakta hai compared to a new launch near Sector 150?
