@Sheeraz,
I have a very good suggestion for you...
There is a society called Foreign Office Employees Cooperative Housing Society (FOECHS). It is adjacent to CDA sector I-16.
At the moment, development work is going on at full speed and they are promising possession next year. Development standard is good. Plot-holders are educated people diplomats etc. And most of them are living abroad. Very decent community.
It is not yet a 'hot' property because the society has not yet opened third-party transfers so the prices are within range for middle class. But once they open third-party transfers, the prices will shoot up. At the moment, a 'market price' is not yet established but it can be a very good investment.
The difficulty is that you may not be able to get transfer in your name, but you can execute very strong agreement with the legal help to secure your title deed. After they open third-party transfer next year, the plots will enter the market and prices will rise.
You can ask for details at the society office - located inside the compound of ministry of foreign affairs on constitution avenue. The society employees can arrange a sale of plot if you go and talk to them.
