₹45 lakh in rent over 8 years — time to buy, but what?

8 saal se renting kar raha hoon, ₹45 lakh toh rent mein hi de diye. Ab bas, Gurgaon mein apna ghar lena hai. Budget ₹1.8 Cr tak hai. Dekh raha hoon Dwarka Expressway par 2BHK ₹1.3 Cr tak mil raha, ya Sohna Road par 3BHK same range mein. Confused hoon, 2BHK for appreciation near Golf Course Extension ya 3BHK for space in Sohna? Godrej Properties aur M3M ke projects mein bhi yahi dilemma hai. Rental yield kiska better hota hai? Kya karoon?
