Unsure about big discount on resale property?

15% off market price for a 3BHK in DLF City Phase III – sounds too good to be true, right? I've been tracking a resale property listed at ₹1.8 Cr. My data shows new projects, even from good builders, won't drop more than 2-3% usually. But secondary market mein, from my experience, real leverage milta hai. If seller ko jaldi hai, you can often push for 5-10% off the *actual* market value, especially after accounting for stamp duty and registration. This makes the total cost of acquisition way better. The trick is finding out seller ki real urgency. Any tips on uncovering that? I always look for properties listed for months. Is there a catch I'm missing here? Hope this helps someone looking beyond new project hype.
