You can't buy much real estate with one year's contribution so you probably would have to wait a few years until you accumulate enough funds to invest in a deal (unless you have some other retirement account which you could rollover into SDIRA). 

Set up a self-directed IRA or truly self-directed Solo 401k plan (if you are eligible), perform tax-free rollover and invest in real estate inside of a qualified retirement plan.

These lenders offer short terms such as a year or less - it allows you to exit and roll over to the A side without penalty.

I assuming this is a trad 401K that you can not roll over or withdraw w/o penalty, and therefore the elaborate scheme.  

And don't forget to roll ove some of your 401k or IRA into a Roth IRA! 

Half the wholesalers out there would steam roll over her and steal her house.

I would roll over some of my old 401k to the solo401k to start the funding.I just dont know how the k-1 negative ordinary income would flow into the Schedule C and how the cap gains at the end would flow? 

As an alternative to taking a distribution from your 401k, consider the following:If you are self-employed (i.e. active self-employment earned income separate from your w-2 income) with no full-time w-2 employees, you can set up a Solo 401k and then rollover your 401k funds once you leave your current job.

Please see additional considerations below.If you are eligible to set up a self-employed Solo 401k (or have a 401k plan through an employer which accepts rollover contributions and allows for 401k participant loans), another alternative which would avoid taxes and penalties would be to transfer your funds to such a 401k plan and then take a 401k participant loan.

In that case, the plan won't allow you to invest in real estate (or even rollover contributions to another retirement plan that would until you quit your job).2) If the plan allows you to take a 401k loan, that might be one option to access funds to invest in real estate (i.e. you would borrow the funds and then purchase in your own name or an entity that you own personally).Here are the general considerations regarding 401k loans.401k Participant LoansIf your 401k plan allows for 401k participant loans, the maximum loan amount is equal to 50% of the balance up to $50k.
