Renting for years, now eyeing MVN Athens investment

Honestly, I'm just fed up of renting and my landlord hiking rent every year. I've been looking to finally take the plunge and invest, maybe for rental income. MVN Athens in Greater Noida keeps popping up, it's completed which is a plus. The price range looks decent, but I'm trying to figure out the real picture. What's the actual capital appreciation been like since its launch? Has the price moved much? Also, what kind of rental yield can one realistically expect there? I'm worried about high investor ratios leading to a 'ghost society' feel and affecting future rentals. Any current owners or real estate agents here know about the end-user vs investor mix? Trying to do my EMI vs rent math properly.
