The hidden math behind upgrading to a 3BHK in Ghaziabad

Okay I'll be honest — I completely underestimated how confusing this process is. I'm in a 2BHK in Vasundhara with an EMI. Considering upgrading to a 3BHK or small villa in Indirapuram. The price jump is huge. Is that premium truly justified for future appreciation or rental yield in Ghaziabad? Or should I just stay put? Thoughts?
