I do private lending in a self directed IRA with Equity Trust Company as my custodian. Often, I am not able to keep all of my ira funds invested in active loans so I would like to be able to keep the money that is not invested in loans in a liquid "money market" type of fund on a temporary basis. My goal would be to be able to access those funds fairly quickly if more lending opportunities become available. Does anyone know of a money market mutual fund or a fixed income fund that could be used for this purpose within my Equity Trust IRA?
