Funds

Aoa

Can you please advise one the following:

1) if a buyer wants to move funds from overseas to complete a home/land purchase, what is the best method to transfer the funds avoid complications? Via money transfer agent to transfer overseas bank to pakistan bank?

2) can leave the funds in an overseas bank account and can the agent request the funds from pakistan?

3) how will the purchase transaction take place? Does the selling agent request the money from your pakistani or overseas bank account?

3) do you need a bank account in pakistan?

4) i am assuming cash lump sums are not accepted by agents?

I am not sure how the transaction process works and at what point in the buying process - would be grateful if you could clarify.

Thanks
