This will be the main LLC that will invest into your asset or other possible businesses and LLC's. Keep in mind that some states (i.e. California) have rules that you might need to register this LLC as a foreign LLC.
If you open another LLC, your RD Colorado LLC will be able to invest into that one, provided that all prohibited transaction rules are adhered to.
The Colorado LLC is an affordable option, is a business friendly state, and their State Department service team is easy to work with to better bring value to our customers.
If you choose a solo 401(k), it utilizes a trust, which does not need to be tied to any particular state.
