Sohna mein floor-rise premium is a builder's myth.

Okay I'll be honest — I'm looking to upgrade from my 2BHK near IFFCO Chowk to a 3BHK or maybe a villa in Sohna, but these floor-rise premiums? Matlab, what's the logic? Ashiana Housing mein bhi dekha, 4th floor pe ₹15L extra for what? Just a better view? My current 2BHK is ₹1.2 Cr, but a 3BHK at ₹1.8 Cr plus these premiums feels like a ripoff. Shouldn't secondary market deals offer more flexibility on this? Brokers bhi bolte hain direct builder se better deal milegi. Disagree? Tell me why.
