Noida mein 3BHK upgrade ke liye tax hacks?

₹1.5 crore for a 3BHK in Sector 150 seems steep. Currently in a 2BHK, planning to upgrade. EMI chal rahi hai. Heard about tax hacks beyond Section 24 interest deduction. Like, 54EC bonds for capital gains? Anyone used them effectively for a property upgrade in Noida? Just trying to justify the jump.
