Whitefield search from Dubai – is it even possible?

Whitefield and Sarjapur Road keep coming up in my research, but I'm based in Dubai, so a site visit isn't happening anytime soon. I've been checking out Prestige Group and Sobha Ltd. projects, mostly 2BHKs, but the whole process feels super complicated remotely. How do other NRIs handle property registration and legal stuff without being there? Getting a reliable power of attorney is a big concern. Also, what's the real deal with rental management? Are those 3-4.5% rental yields actually achievable, or is it just on paper? I can't be there to deal with tenants or repairs. Should I even look at under-construction, or is ready-to-move a safer bet for someone like me? Any tips on trusted property managers or legal folks for remote buying would be amazing.
