Noida's 'all-inclusive' pricing is a myth, right?

Who else thinks builders in Noida intentionally hide possession charges? Laureate Buildwell in Sector 17A quoted a price, but the all-in cost for stamp duty, PLC, electrical connection is always 15-20% higher. Yeh bilkul scam hai. They wait till the last minute. I work in real estate, but for myself, it's different. Change my mind.
