Palm Olympia 3: Dubai se dekh raha hoon, resale aur rental?

Palm Olympia Phase 3 ka current pricing seems high, considering the under-construction status. I'm based in Dubai, so can't do a site inspection myself. What's the real resale market like for this project? Is there good liquidity, ya ghost society ban jayegi? Also, rental yield kya expect kar sakte hain actual mein? Power of attorney se sab manage karna padega, so exit strategy clear honi chahiye. Any insights on the investor vs end-user ratio yahaan?
