Vetting a self-directed IRA custodian

[Chase Gochnauer]

Hello, I have someone interested in purchasing some real estate with me, purely as an investor. They will need to do it by rolling into a self-directed IRA to avoid any tax consequences of pulling from their 401k.

I also have some funds I was going to contribute to a self-directed IRA to do the same.

I am having a very hard time finding a good company to work with. It seems that a majority have questionable reviews. Can anybody help provide who they have used and if it has been a positive or negative experience?
