Gaur Galaxy: Is it truly an investor's paradise?

Okay, I'll say what no one says about Gaursons Gaur Galaxy. Just got possession in March, and the investor-to-end-user ratio is way higher than I expected. It feels like a lot of empty flats, which honestly concerns me for future capital appreciation. Everyone glorifies the rental potential, but the actual rental yield I'm seeing for a 2BHK is nowhere near what agents promised. We're talking maybe ₹15k-₹18k, not the ₹20k+ I was told for a ₹70-90L property. Makes me wonder about the exit strategy in 5 years. Is this normal for completed projects in Ghaziabad? What are others' experiences? Disagree? Tell me why.
