If you are buying a home priced at Rs 10,000 a sq ft and the price goes up to Rs 10,200, it represents just a 2% increase and while you do not like it, you can and probably will shrug it off. The seller too probably does not care much, as he is making such a large profit anyway. But if you are buying a home priced at Rs 2,000 a sq ft, a Rs 200 increase means 10% and might render the home unaffordable.
