J Block 2BHK search: Legal issues & builder trust

₹90 lakh for a 2BHK in J Block — online toh yehi rates hain. I'm based in Dubai, can't visit easily. My cousin mentioned legal clarity issues with some projects. Konse builders ka track record sahi hai J Block mein? Gaursons, ATS, Godrej - are they reliable? POA se manage karna kitna risky hai? Any hidden legal costs ya land dispute issues? Need ground reality check, please share experiences.
