Article 23 of the Constitution of Pakistan lays down the right to acquire property, stating that every Pakistani is permitted to buy property in any part of Pakistan. It says:

Every citizen shall have the right to acquire, hold and dispose of property in any part of Pakistan, subject to the Constitution and any reasonable restrictions imposed by law in the public interest.

There can be some restrictions on the exercise of this right, e.g. there is a limit on the amount of land we can purchase. Similarly, some lands may be designated for specific purposes such as hospitals, schools, etc. Other than that, every citizen of Pakistan can buy property in any part of Pakistan.
