How to get a HML loan when using SD IRA for down payment

[Julian Buick]

I was presented an offer to fund a deal through my SD IRA. It was presented to me by a guy that works for a HML. I can use my SDIRA to fund the 20% but would need to borrow the 80% from the HML. This would essentially be a JV deal where I bring the money and the partner would do the work. The question I have is if I have to personally guarantee the loan from the HML isn't that violating the IRS rules of the SD IRA?
Is there another way to structure this? I would not actually be doing any of the work so it seems like I would not be violating the rules. The HML will not lend to their own employees.
