@Matthew Lucherini, hopefully you bought those using a self directed IRA where you won't pay tax until you take distributions.  

Also retiring in 2020 and want to put 401k money into self directed IRA.

Then invest $100,000 into stock market index funds in a taxable account and each year use gains from this to fully fund a Roth IRA or better yet a solo 401K if you go the self employed route.

It does have a lot of useful information--it was the first place I heard about SD-IRAs--but that's it.

I'm wondering if anyone is aware of service providers, and also, how this would work:We have our eyes on some auction properties (IE: county auction) - we have funds within a self directed IRA custodial account, and we also have funds outside of this available for these purchases.
