It will tough to find land in this budget within the city limit as the price of property are quite high. But you can buy in the outskirts of Bangalore like Thanisandra or Sarjapur Road.
If you are looking for plots for lesser price then you can look out for areas like in Devanahalli Kolar Road, Babu Sahibpalya near Hennur, Hoskote Road, Yelahanka and Doddaballapur Road.
In terms of capital gains a plot is always the best choice.Plots in gated communities will be ideal. If going for an apartment make sure that you are buying from good and reputed builders only, as inefficient construction can cause troubles after few years which will increase your maintenance costs.
Plots always bring you more returns than apartments as there is no depreciation. But if you are planning for a home loan, you will get only 50% of the total cost if you are buying a plot. Also you will not get tax benefits for home loans taken against land purchase. But these are just two aspects of it. In terms of investment plots are always the best choice. Also, due to high demands, it is difficult to get an ideal plot. But there is a lucrative option in suburbs of big cities.
Investment in plots is better then apartment because difference in land prices is huge and chances of appreciation are higher in coming years. Flats need maintenance and structure's value depreciate with time. No such case with land. With respect to floor area ratio, demands for plots is moving up. The most important reason is barren land is decreasing and in future demand is going to rise. So make use of those which are available and construct whatever you want.
What I feel is that buying a plot and then planning for the construction of house is one of the toughest tasks. I prefer more for ready to occupy flats wherein we can take possession immediately. According to the study by leading realty broking firm it is found that there is more demand for the apartments and flats which are ready-to-occupy
