Beyond brochure price: Gurugram's real cost

Visited Pankaj Homes Ansal Esencia and Apna Ghar Sunehra Apartment last week. Fed up of renting, so finally taking the plunge. Ansal Esencia ka carpet area theek laga but total cost of ownership including PLC and maintenance kitna padega? Apna Ghar ke builder ka track record kaisa hai? Not sure if their quoted price covers everything. Real advice chahiye.
