Bro Malik,
I've invested in the overseas Golf block by paying 30% down payment and remaining 4 years installment till 2018. There are very few overseas plots and balloting will be done by end of March. The master plan for overseas Golf block is already published. So i agree with Fat man that long term investment is better at BTK.
You can get more details from Bahira website by downloading the application form. Though the registration is closed but you might be able to still find a plot by applying through your overseas relatives.
Bahria customer service told me that they lunched overseas block 1 year ago and last week they have sent the possession letter to the owner to build a home. So my guess is that overseas golf block will be completed in 1 to 2 years since the main theme of BTK is the first 27 hole PGA standard Golf course.so it is a must to make it a reality as soon as possible.
P.S: I was also told that BTK is preparing for the biggest event for March 23rd celebration. I'll share the details when i get them.
