Hello Zubair,
In my opinion, 240 sq yd. double story house should cost you around 1 crore and 30 lacs. But the price may vary according to the location of bungalow, features and amenities offered.
Area of Bungalow:
If you think that the bungalow seems smaller than the mentioned area, then confirm the area firstly form the original documents or you can do the manual measurement to assure yourself on that.
Hidden Things:
You should confirm the price of property from different sources, so that the agent or seller may not trick you. You can contact different agents of the and ask them to provide estimated prices of properties of similar nature. And yes, if you are buying it form real estate builder, then you should be concerned about the material used.
Transfer of ownership:
As per my knowledge, transfer of ownership varies from town to town. So, the related authority that governs property transfer in Gulshan e Iqbal can update you on that.
Other Things:
Just do your own research Zubair. People because of your lesser knowledge try to cheat on you. So, I would suggest you to do the proper research and most importantly pray to ALLAH to guide you in your buying pursuit.
Good Luck Zubair!
