Buying for myself is harder than selling

Honestly, even with my real estate background, buying for myself is different. I'm eyeing Ansal Aastha Mig Zone in Rajkot, completed and around ₹30L. What's the investor-to-end-user ratio like? Is it a ghost society? A high investor ratio always worries me about resale and long-term ROI. What actual rental yields are people getting? Is selling later really difficult?
