Back in 2010 First Western Federal did a loan for me on a 1890 4-family.

You should run an equitable screening process and not run afoul of any rules regarding Fair Housing (whether federal, state or otherwise).

@Klodian H.Please note that while there is certainly asset protection for 401k plans at the federal level generally, please note that for individual Solo 401k plans (as opposed to a 401k plan that you might have through a day job) the federal protection outside of bankruptcy does not apply such that one must look to the state level where the creditor protection may not be as robust. 

Lenders follow a set of fixed underwriting guidelines set by the federal government thru Fannie Mae and Freddie Mac.   

I attempted something similar as a W-2 employee.My Gross paycheck is as follows$4,200 Gross$300 FICA Tax$1300 - Federal/State/City Taxes$2,600 NetOne week I decided to put 100% of my paycheck into my 401K and take it out as a loan.$3,900 went into my 401K and I took out 50% which was close to $2,000.It was a no brainer for me not to do it.

PenFed and Navy Federal if you have connections to the government. 

Hi @Liz Murphy@Tucker McCarthy took the words out of my mouth (keyboard, whatever...).The only other thing you'll need to do is request a Federal EIN; also simple.I don't see why having it in an LLC would help, but I'm not an atty.

It would also appear, that I would not be paying any income tax on the roth contributions since I already paid those taxes, but I would be liable for taxes on any roth earnings that I would take out at my federal/state income tax rates since I am withdrawing early ( I am 32 years old). 

I think most people would agree that poverty is very much a pressing social problem in the USA.I remember in health class in NY back in the 90s, I had to learn how to feel around for testicular cancer on a nasty little silicone model, and yet no teacher in any class spent even a minute to explain how to put together a monthly spending budget.43 million Americans live below the federal poverty line and 9,310 American men were diagnosed with testicular cancer last year.

And when I did look this up, it wasn't a mortgage guideline I found, it was a federal law.Granted, Wells Fargo often has a hard time understanding that they can't just make up laws and do what they want all willy nilly like they run the world, which is exactly why they get fined all the time.
