Just moved in! Things nobody tells you about Noida

Okay I'll be honest – nobody told me about the hidden costs after possession! Just moved into Skydeck Infrastructure in Block B last month. OC mil gaya smoothly, but the PLC charges were insane! Like seriously, almost doubled my initial estimate. Is this normal, yaar? Also, I'm seeing wildly different rental yields advertised online versus what people are actually getting. Matlab, the society is great, but the rent I'm getting is way less than expected. Anyone else facing this? Should I have considered resale instead of under-construction? I'm thinking if I should sell after a year or two for better ROI. Any tips? Hope someone can share their experience.
