If you don't show your income here in the U.S. It might be difficult for you to get a loan here. Maybe you can supply the down payment money to your relative and they could qualify for a loan.
Feel free to email me and I will point you in the right direction by referring you to a mortgage professional.
If you are able to purchase a home here, I will refer you to a good property management company.
