Hidden costs buyers only discover after possession

Okay I'll be honest—I completely underestimated hidden costs. Everyone talks about the base price, but PLC charges toh itna zyada hota hai! And now I'm hearing about these maintenance charges after OC. Honestly, I had no idea. I'm looking at a 2BHK near Naya Gaon. Should I factor in like, 10% extra for all this? Raghunandan Infra Projects is one option. Are there any other builders with more transparent pricing? Any tips to avoid these surprises? Ab samajh nahi aa raha.
