People have had their life time money multiplied by zero in case of Bahria (I myself know many such persons who lost heavily in Bahria Enclave 2 , Bahria Phase 8; and DHA Valley as well).
CDA is white elephant and it's projects now take decades (I-12, Park enclave etc.)
So the point is, you can't just trust a brand name, sit back, relax and comeback some day with your investment multiplied many fold...
