There are a number of builders and developers active in Bosepukur and Kasba. Aspirations Bellagio by Somani Realtors and Roopkatha by Parsari Group are two of the famous residential apartments in the region. Ballygunge railway station is at a close distance from Bosepukur making it a good place in the heart of the city. The only negative i can think of for the region is that it might not give good returns as some of the other upcoming regions of Kolkata especially in the suburbs. Overall Bosepukur Road is good for residential point of view but as an investment tool, there are better options.
Bosepukur located in Southern Kolkata not very far from new Ballygunge offers a decent investment opportunity. The current price for a residential apartment in Bosepukur and neighboring Kasba is between Rs 3000 to Rs. 4000 per square feet. The rental prices on an average for a 2 BHK apartment fluctuate between Rs. 7000 to Rs. 10,000 depending on the location and amenities. While the region offers good growth prospects as a number of builders are active in the region, there is nothing in the pipeline to sagest that the area can be a gold mine in terms of a long term investment. I would suggest you to check out properties in eastern suburbs like EM Bypass that can give you better returns over the same period compared to Bosepukur.
Bosepukur is in south kolkata and as far as i know south kolkata price is getting increased. So it would be good idea if you are doing investment here.
