Currently the average selling price going on for a 2 bhk in Tumkur Road is Rs 14,000. In 2016 you can expect Rs 16,000 ( minimum). the price also depends on the size of the apartment, amenities, connectivity etc.
Tumkur road was considered as a village in the outskirts of Bangalore but now due to rapid growth in real estate sector it has transformed into a part of the city. I would suggest you to go for plots rather than residential flats.
The area is well connected with other parts of the city like It is just 8.1 km from Bangalore City Railway Station and 30 km from Bengaluru International Airport. Close to Peenya Industrial Area, the locality offers easy connectivity to Magadi road at just 8.1 km
