Private money from foreign nationals?

[Michael Wentzel]

So I am an US citizen, but have lived and worked overseas for many years. We have a growing portfolio of rental properties back in Colorado and would like to keep growing it. The last couple years we have started using private money lenders and it has worked quite well. So far all of the private money lenders have been US citizens. However, I have some foreign friends who would do some private money lending if was possible. I am just a bit fearful of stepping into this area since I don't know the legal implications.

Does anyone have experience in this area? Do I need to run in the other direction?
