Michael, You will most likely incur UBIT, using IRA funds.

You could also potentially pay yourself a salary through the company, which could create retirement plan opportunities, such as contributing to a solo 401(k) or SEP IRA.

The owner of each property (you, LLC, trust, IRA, ect.) would have to execute a management contract with the Master LLC, so the Master LLC could legally act on behalf of the property owner(s). 

What MAY make sense is to setup a Master LLC that operates like a PMC and collects all your rents, pays all your property-related expenses, etc.The owner of each property (you, LLC, trust, IRA, ect.) would have to execute a management contract with the Master LLC, so the Master LLC could legally act on behalf of the property owner(s).Check with Account Closed read our 

If you are identifying individual private money lenders, you can consider having a conversation with them about using their IRA, previous employer 401ks, or other retirement accounts.

I do not see that really being beneficial with BP and other forums, for example here on bp I would say atleast 50% of the responses we see on things like IRA's, LLC's etc are really bad advice.

When using a Roth IRA, your Roth IRA is a tax-exempt entity, therefore, any depreciation deductions that pass through the LLC, can't be used on your personal tax return.

@Andrew MontgomeryNot sure if you can access some of your 401k and roll it into a self directed IRA to start  investing as a passive investor in someone else's deal, to learn while you earn.You are looking at it linearly.

My mentor left me his home, an inherited IRA, and some brokerage money. 

I did a IRA withdrawal of 300k to buy 2 condos in May/June 2024.
