Hi Pankaj - property investment for appreciation is a little out of fashion these days. I guess, most of us folks are investing in the stock markets for returns. However, there are some areas in Pune when the prices currently are not very high and once infrastructure improves, you can sell at a higher price. At the very least, you may be able to rent it out.
1. Hinjewadi - in the IT belt, hence will see demand.
2. Keshavnagar - proximity to Koregaon park, Kalyani nagar. Easily accessible to IT employees.
3. Talegaon Dabhade - advantage here is of proximity to MIDCs (Talegaon, Chakan, Bhosari etc.)
Hope you found this information useful. All the best for your investment plans in Pune.
