Quote from @Eamon Conheady: I was purchasing a multi family through an IRA LLC and was utilizing debt to finance it, requiring a non-recourse loan.

I hired an IRA-approved valuation company to value that note at that time.

My CPA also has an investment we got in with double digits returns that we rolled our IRAs into but you could probably put cash into if you would want to live off of it before retirement age.I would never recommend someone stay in a job they hated just for the money.

Yes, 401(k) plans, IRAs, SEP-IRAs and all other kinds of retirement plans are still the backbone of your wealth accumulation, especially if they are self-directed.

Cash from a self directed IRA How did you add value to the deal?

Fully fund IRAs and 401Ks7.Work less ("I think I earned it" ... a few good men)

Does anyone know a reputable or comp with competitive rates to set up a checkbook IRA?

My IRA LLC has a name.

Real Estate, Self Help/Health, Starting my own Direct to Seller Business, Roth IRA, Crypto, and my family! 

As apples to an IRA Hope that makes sense .
