Small tax hacks for Bangalore home buyers people miss

Been renting for 5 years now, fed up of paying EMI to landlord. Finally looking to buy a 2BHK near Sarjapur, budget around ₹90L. Everyone talks about 80C and 24, but I just found out about some stamp duty exemptions for women or first-time buyers in some states. Is this applicable in Bangalore too? What other small tax hacks or benefits do people miss out on? Builders toh bas prices batate hain.
