This is a just my observation about the real estate market in Bangalore and Trivandrum. I recently bought a plot in Bangalore !( can not say it is in Bangalore as the place is very far away from Bangalore city.)
I purchased a 2064 sq ft in xxxxhalli :-) in Old Madras Road. It is very near to the Volvo factory in Bangalore. It cost me around 9 lacs. I am not sure whether it was a good deal or not. But later I found that the local people sold that area to the builders for about INR 225 per sq ft. This is a rough calculation. But having said that, I am getting the advantages of a fully built Township features at my place. So I am consoling myself. :)
I bought a flat in Trivandrum in 2008. It is a 3 BHK & cost me 34 lacs. Again at that time I was hoping to increase the price of flat in future, but now if I buy the same flat, there is hardly any change in price or no change.
But at that time I had inquired the price in Bangalore as well. The price is drastically changed during these period.
But I know that the market value for a city like Bangalore is nothing comparable to Trivandrum and again I will say that it is good that the flat price has not come down in Trivandrum even at the rescission time:)
