Advantages of Custodian vs. Checkbook for RE Solo 401K

[David B.]

We are getting ready to purchase our first investment property, a single family house to rent, using a self-directed Solo 401 K.

At first I was leaning toward having checkbook control, but the cost for a custodian-managed account is reasonable, and I am thinking it might be good to have a custodian take some responsibility for paperwork and banking.

What are the disadvantages of using a custodian, other than the slightly higher annual cost? The one I'm considering does not charge per check, so that is not a concern. I assume I can get checks issued very quickly if I am making an offer on a house.

I appreciate any help or suggestions.
