Construction-linked plans are often a bad deal

Okay, I'll be honest — I completely underestimated how confusing this process is. We're currently in a 2BHK near Noida Extension but thinking of upgrading to a 3BHK, maybe even a villa, in areas like Chaukhandi. My budget is around ₹1.2-1.5 Cr. Already have a home loan, so payment plans matter. Construction-linked payment plan vs down payment, which one makes more sense these days? Is the premium for a 3BHK with Brickland Projects Pvt Ltd really justified? Aur, kya koi specific 'price correction zone' hai Noida mein jahan abhi bhi value mil sakti hai? Connectivity to Delhi is still a concern, not sure if the price jump is worth it for sectors further out. Builders like Gaurs Group offer these spot discounts, but are they real savings ya bas dikhawa hai? Seeking genuine advice on how to approach builders for better deals. Kya lagta hai?
