Gurgaon's ready-to-move projects are overpriced, ongoing is the real deal.

Under-construction risk in Gurgaon is completely overblown for a good builder, I feel. I'm in Dubai, eyeing Signature Global City Phase 1 (ongoing) and Generous M3M Xpressway 114 (completed). My agent is pushing Signature for appreciation, but being ongoing, what's the actual possession timeline and OC status? I can't do a site visit. M3M Xpressway is ready, but it's much pricier. For a 4.5 Cr flat there, kya real rental potential hai? As an NRI, I'm worried about managing it from afar, finding a reliable property manager. Total cost of ownership, including all the hidden charges and ongoing maintenance, for both projects kitna ban jaayega? Should I even consider ongoing projects without being there?
