I feel you should go for localities like Koramangla, Banshankari Stage 2 and Yellahanka recorded a rise in rental values. Koramangla and Banashankari Stage 2 grew by 10 per cent each, while Yellahanka reported a 9 per cent increase in rental values as compared to the quarter ending March 2013
Koramangla has very good infrastructure. It is strategically located and almost all main roads in this locality have got commercialised. All these factors are driving the residential market of this locality. So Koramangala is the most preferred location for renting a house. :D
Ulsoor has seen almost 23 percent increase in rental values in the last quarter. As per my knowledge, the rental values in Bannerghatta road and Banshankari is going up by nine percent.
