Top city verses roshan pakistan e-16 (private society)

Top city and roshan pakistan e-16 both are private society. Roshan pakistan got noc and location is good along g.T road. But plot are also available on instalment in rp e-16 next to cdechs. Now people are selling plot in loss in rp .

Top city is also private society like roshan pakistan. Can top city be risky like rp at the end we sell plot in loss.

I want to buy in Top City..any body who can help me...i have got strong recommendation and inside news from CAA and airport management that ...the link to new airport is through Top City..and it is having all the chances to get a price jump within next 6 months..

Tahir no comparison between Top City and Rp...Top City due to its ideal location is far better and safe for investemnt.
