I've been with Entrust, and no complaints. They funded our SDIRA very quickly into our LLC, so we have full checkbook priveleges for our investments. Yes, there are some minimal annual fees, but why shouldn't there be? They aren't earning commissions on investments since we invest all our funds into real estate (fix n flip).
Yes, there is $800 per yr on the LLC in Ca, but considering the tax free profits that we've been earning, who cares? Having the LLC give us alot more freedom to have control and to be able to act promptly without the delays. Without the LLC, the custodian has to fund all your transactions. They can't do it as fast as you can.
If you are shopping for SDIRA custodian, remember there is usually an "exit fee" when you eventually cash it out. This can be steep if your account has had substantial growth. For this reason, we are starting to withdraw some each year, now that we are over 59-1/2. We can now withdraw without IRS penalty and invest the funds in our Corp. As the funds continue to grow in our corp, there will no longer be fees paid to exit the SDIRA acct, since we are doing so before the growth becomes too great.
All these things should be considered when setting up your SDIRA, plus alot more. Invest a few bucks to talk to a QUALIFIED tax advisor before jumping in.
One more thing that I've always liked about Entrust. They offer ALOT of seminars on RE and note investing (and more). Some are live and some are webinars. They aren't all free, but they don't charge alot for the ones you have to pay. They often have a Tax Attorney as part of the panel for their seminars. You need to stay educated in this arena to avoid costly mistakes and to stay on top of any new regs that may be imposed on SDIRA accounts. So, you can add my vote for Entrust.
