Noida property: Hidden costs beyond the base price?

Okay I'll be honest - I'm based in Dubai and can't visit Noida easily. Thinking of investing in Nitya Azaad Residency vs Antriksh India Grand View. Nitya looks cheaper upfront, but kya kisi ko pata hai about hidden costs? PLC charges wagera? Antriksh is obviously more expensive, but carpet area efficiency kitni hai? Also, resale value mein kaunsa better rahega after 5 years? Need a property manager, so rental potential matters. Should I just stick with a builder with a good track record?
