@Dion DePaoli has the expertise to look at the possibilities to facilitate a loan under a supervised process.

@Brandon Powell That would absolutely be a prohibited transaction in the eyes of the IRS.By providing the loan to the buyers via your 401k, you are facilitating the sale of the property.  

This S-corp could more commonly be called a "special purpose vehicle", as its sole purpose is to facilitate your ability to obtain credit.

This will facilitate one closing.

You might just facilitate exactly the opposite outcome of what is best for the real estate investing community at large.

MY CREDENTIALS ARE BELOW:BROKERING WITHOUT A LICENSE WOULD BE IF THEY REPRESENTED A SELLER OR BUYER IN FACILITATING A DEAL WITHOUT ANY RISK AND/OR INTEREST EQUITY IN THE DEAL before CLOSING. 

They should facilitate the sale, but not make decisions for the Seller.

This greatly facilitates the use of trusts to pass property to heirs and minors.

In Illinois the State Licensing Act is clear: Anyone facilitating a real estate transaction for compensation of any kind must be licensed.

All states have RE license laws, those representing or facilitating sales, the laws are not consistent and do vary, some with wider doors than others, but wholesaling can become an issue.I also see you teach, that may explain it. :)
