My Ansal Aastha Mig Zone rental reality check method

Is anyone else finding it tough to get real rental estimates for Ansal Aastha Mig Zone? I'm fed up of renting, seriously considering buying here for investment, but every broker gives different numbers. How do you guys verify actual rental yield? I'm worried about high investor ratios leading to a ghost society, making it hard to find tenants. What's the occupancy like there, honestly? Thinking long-term, this affects resale too. Any tips on checking genuine demand before I take the plunge? It feels like a crucial step most people miss.
