Receiving Investment Money from Another LLC

[James Letchford]

I have a friend that has a successful non-real estate business in an LLC. He's interested in passively investing in the real estate work that I'm doing, but would like to do so from his LLC.

Here's are my questions:

1. Is there any advantage for him investing via his non-real estate LLC? I.e., tax advantage, write-offs, etc.?
2. Is it unclean for his non-real estate LLC to partner with my real estate LLC on a project?

Thanks in advance for any inputs.
