Fed up of renting, finally taking the plunge!

Visited a few projects on Golf Course Extension Road last weekend. Fed up of renting, landlord ne rent badha diya phir se. Finally taking the plunge, EMI vs rent math ab theek lag raha hai. But yaar, tax benefits ka kitna real impact hota hai? Section 24, 80C ka max out kaise karein? Koi tips hain kya, specially for first-time buyers?
