I would urge you to get your financing in order first ( it you are not paying cash)
If you do not have a credit score in America, there are lenders that can finance you using alternative methods.
You will also need to invest some time here in the states. The real estate buying process can require a lot of work on your part. It would be best if you can be here for a good portion of the time.
If you are looking to buy this property as an investment and will be renting it out, you should start vesting property management companies NOW. Find one that will be a good fit for you.
Best of Luck t you,
