Paying for Overseas property

What is best way to exchange my money when I must pay for property overseas?

Hello, my father owns

Hello,
my father owns half a commercial property in Texas, and he is overseas now, and I am in Texas. His partner got the money for it and wants to buy it from my father. My father wants to send me the power of attorney so that he doesn't have to come all the way to Texas to make the sale.
Can you please provide me with a complete solution, because I know nothing about this subject, and if there is another way can you please help me out and explain it?
Thank you.
