Who does mortgages for self directed 401k owned properties?

[Michael J Scanlon]

I’ve had my money in my self directed 401k in a TD Ameritrade account for two years and done very well. I now want to buy a property that will be owned by my 401k. I know the ins and outs of this (cash flows will go back into the retirement account, if I ever sell then proceeds go into my retirement account, etc.) However, I can’t seem to find a lender who will do a mortgage for a retirement account owned property. Does anyone know any specific lenders or have a general idea of where they found a lender for theirs?
