Ghaziabad property tax hacks: What are we missing?

Budget finalized for my third property in Ghaziabad, but I'm trying to optimize the tax part this time. I'm eyeing a 3BHK in Indirapuram or maybe Crossings Republik, around ₹1 Cr. From my experience, Section 24 and 80C are standard, but I'm wondering if there are other, lesser-known tax benefits specific to property investments here. I've seen some discussions about capital gains exemptions like 54EC, but are people actually utilizing these for properties in Ghaziabad? Like, if I sell my old flat in Vasundhara, what's the best way to save taxes on that gain when buying a new one? What's your take, especially if you're holding property for longer terms? Any 'hacks' I'm missing?
