Hello BP,Because of the rules, it is not possible for the owner of a Self Directed IRA to loan money to their LLC's.  

I have interests in multi family units for cash flow and also setting up a self directed IRA to boost retirement.

My IRA is a Roth, no problem.

Just like any skill in life, learning how to manage your family's finances takes time and effort and they don't teach personal finance in school (which is beyond comprehension but that is a conversation for another post).My recommendation would be as follows:1 - Figure out your monthly burn rate (how much you spend)2 - Set aside liquid reserves equal to 6-12 months of your burn rate (more if you are self-employed, commission-based, have unstable work)3 - Contribute to 401k at least equal to the employer match4 - Research Roth IRAs and, if qualified, this may solve both investing excess funds and saving for children's education as Roth distributions can be penalty and tax free for qualified education expenses (and other qualified distributions)5 - Regarding what to invest the Roth, 401k, or a regular brokerage account in, you can learn how to come up with a diversified handful of low cost index funds (or ETFs) that are easy to purchase and manage.  

I am looking for someone in Minnesota I can meet in person who is an expert on self-directed IRA's. 

Thanks in advance for answering this for me:If we take money from our IRA or SEP to fund an investment property, what kind of tax implications would that have? 

i wanted to open a checkbook IRA with the LLC in Wyoming, how do I go about doing that?

I know it is kind of confusing, but it will look something like this:Wife sells to LLC------------------> Partnership LLCWife receives SOME cash to balance out the 'equity' shares.Partnership LLC is composed of the following, all equal partners:AG SD Roth CashAG CashPartner 1 CashPartner 2 CashWife ~ Equity shareWould this be considered a 'prohibited' transaction for my SD-IRA?

@Vivian Cullen The owner of a self-directed IRA may not personally guarantee any loans taken by the IRA.

After doing rental research today and crunching some numbers, and I think I'd run out of money too soon, even with my IRA and social security.
