International Investors for Domestic Deals

[James Letchford]

I was recently traveling abroad (Australia) for my day job and told some longtime friends of mine about the real estate investing I'm doing in the US. They were immediately intrigued by my approach/success and wanted to know if there was an opportunity to invest. I wasn't able to find anything in the forums that addressed my questions, so here's what I'm looking to be answered:

1. How can I legally accept foreign currency to do domestic deals?
2. Is there a special business structure that I need to form/adhere to in order to make this proper?
3. What are the tax implications for me and my foreign investors?
4. Is there anything else I should consider by taking on foreign investors?

Thank you in advance for your response(s).
