Mohali investment: Is it already too late?

₹1.8 Cr for a 3BHK in Sector 25, Corona Group project – is this actually the going rate now? I'm fed up of renting, my landlord just raised rent again, so finally taking the plunge. But honestly, I think Mohali has peaked for investors. Everyone glorifies the growth but nobody talks about how much is left. Are we just buying at the top? I'm looking at the EMI vs rent math and it barely makes sense if appreciation slows down. Disagree? Tell me why.
