Is this legal use of a Self-Directed IRA

[Bob Sanders]

I am a real estate agent and property manager with about a dozen properties and I plan on growing significantly in '23 and '24. My brother is a financial advisor and he was telling me that he has an IRA and he regularly buys and sells stocks within his IRA and collects commission on those transactions as income. I have an IRA of my own with 100% stocks. I'm paying an advisor every time I buy or sell a stock. Would it be better to convert my IRA to a self-directed IRA and then pay myself the Realtor commissions for each property that I buy or sell within that IRA? That would be legal right? Like it's the same thing my brother does. I think I could do better with real estate than the stock market and I would limit each frictional transaction cost by getting paid a commission myself instead of paying someone else a commission.

Furthermore, would I be able then pay myself a 10% management fee to manage the assets within my self directed ira?  Would that be legal?  I think it would be but perhaps someone here has expertise or experience in this scenario.

I do not want to live in any of these properties nor do I want to sell or buy any of these properties to myself or a relative.  all positive monthly cashflow would be paid directly back to the ira (same with the converse scenario of potentially negative cash flow).

Frustratingly my accountant provided almost no guidance in this matter.  He said, "welp, make sure you do your homework on that."

I would think that paying myself a regular fee for the normal sale and management of a property within an IRA would be legit. But any guidance y'all can give would be appreciated.
