My Ghaziabad flat hunt: Hidden costs are a nightmare

Sector 6 mein Shri Jee Developers ka project dekh raha tha. Kids have moved out, ab bas ek manageable 2BHK chahiye. Everyone talks about the initial price, but nobody talks about the hidden charges! Builder agreement mein sab smooth lagta hai, par possession ke time pe ₹5-7 lakh extra lag jaate hain – OC, electricity, maintenance fund... is this normal for Ghaziabad? Secondary market mein bhi itne chhupe hue kharche hote hain kya? Disagree? Tell me why.
