Ghaziabad's Top Builders pricing is absurd

Spent Sunday checking 'Top Builders' corridor. Builder ne final cost mein hidden charges add kar diye, brochure mein kuch aur tha! I'm in a 2BHK in Indirapuram, thinking of a 3BHK. Top Builders mein prices itne upar kyun gaye? Last 1-2 saal mein jump justified hai kya? Wait karun? Already home loan chal raha hai.
