Is resale the real deal for investors in Chandigarh?

₹1.5 Cr for a new 3BHK in Sector 49 feels steep, even for an investor like me who knows the market. I've been checking out secondary market deals, wondering if that's where the real value is in Chandigarh now. How much negotiation room do you typically find on resale flats vs new projects? For investment, are floor-rise premiums ever actually worth paying? Getting conflicting advice, honestly.
