Sohna flat hunting: What hidden costs did you find?

Been renting for almost a decade now, and honestly, this year's rent hike was the last straw. Finally taking the plunge in Sohna, looking at places near Golf Course Extension Road. One thing I figured out doing the EMI vs rent math: people forget the *real* cost of maintenance and property tax on top of EMI. Builder like Godrej or M3M ka flats, maintenance can be hefty. So, EMI ko sirf rent se compare mat karo, total outflow dekho. Hope this helps someone planning to buy.
