Dear Saeed,i am working in Kuwait so every six months i visit to Pakistan,
mostly i invest in Bahria or Dha and Allah give me much return on my investment.
First time(three months before)i invested in zone2 B-17 E block and top city.
In my opinion zone5 is much much better then zone2 Bahria phase7,phase8 F1 or safari valley also Dha phase2 new blocks K,L,M,N,P also good for investment.
There is many ways to check the market,visit OLX there is many dealers so you can get the idea.
Go to phase7 there is many real estate offices check the local market some times by luck you can get little cheap means if some body need urgent money or need one day cash.
Don't give to any dealer (token or biana money)if you deal any plot then first of all visit your self if you like then tell to dealer to call real owner front of you if between you and owner final the deal then go to Bahria office with owner which is in phase8 clear your plot then pay to owner.
When i go vacation some time i visit but mostly i did't visit,i have two dealers which are in Dha and Bahria so i call them ask the market and many times they call me to inform the market value some time they offer me investor price plots if some body need urgent money.
I trust them and they trust me.
More then five years i deal with them and also my eyes on local market so i know what is going on in market.
If you need any help then sms me +96597271971
My good wishes are with you.
