Keep Idle Cash Working in SDIRA

[Keith Groshans]

My preferred investment in my SDIRA is mortgage notes. The monthly payments are great, but the issue I am running into is what to do with idle cash. My custodian does not have a money market or similar sweep account to keep idle cash earning. If I wait until accumulating enough cash in the account to buy another note, this will kill my yield. They do offer access to mutual funds, but I do not love this option. I am wondering if transferring the cash periodically to a standard brokerage IRA account may be my best option. If so, any one have experience doing so in a way that does not accumulate a lot of transfer fees? Any other strategies I should consider? Thanks!
