Gurugram NRI: Hidden truths of remote management?

Spent the whole weekend looking at virtual tours and reports for Gurugram properties, focusing on Dwarka Expressway and SPR. I'm based in Dubai and can't do a site inspection myself, relying on my brother's visits. I'm eyeing a 2BHK, perhaps around ₹1.5 Cr, from builders like DLF or M3M. The plan is for long-term investment. My main concern is managing the property remotely. Is the advertised 3-4% rental yield near Cyber City actually achievable? I'm worried about finding a reliable property manager and the complexities of power of attorney for an NRI. What are people's real experiences with rental income versus what's promised? Also, how transparent are the legal processes for remote buyers? Should I stick to ready-to-move for less hassle, even if it costs a bit more?
