Noida investment: Resale reality check nobody talks about

Okay I'll be honest — resale properties in Noida are more complicated than I thought. I'm based in Dubai, so site visits are tough. I considered a flat near the metro in Sector 75 for rental income, but the paperwork seemed messy. Anyone else find resale documentation a headache? Is it worth the hassle, or should I just stick to under-construction with RERA? Maybe Grihapravesh Buildteck in Block B is safer? Need a property manager if I buy. What's the resale market really like?
