I am wondering at this point if I would be better off selling this investment and just keep the ones I have already completed until i can build up a stock pile again

Following is how the ROBS 401k works: Because you directly rollover your IRA or former employer 401k, 403b, Keogh, SEP, SIMPLE, or other eligible account, to your new ROBS 401k  plan, which then funds your business, you incur no taxes or early distribution penalties.Unlike traditional 401k plans that allow for a 401k participant loan, that is, borrow up to 50% of the account balance not to exceed $50,000, the ROBS 401k for business financing plan allows you to use all of your retirement funds to fund your start-up business.The ROBS 401k funded corporation allows you to draw a reasonable salary from the business.ERISA 408(e), and ERISA Reg. 2550.408 list information regarding the use of 401k funds to invest in employer stock of the employer’s corporation.The IRS formally commented on the use of 401k business funds on Oct 1, 2008 by issuing IRS memo commenting that the use of retirement funds is not disallowed but continue to be reviewed by the IRS.The use of retirement funds for business funding entails the 401k purchasing stock shares in a C-Corporation.

What you are proposing is called dollar-cost-averaging and works well in stocks. 

Stock investing is one of those streams even though it may not seem like it when it is sitting in an account.

Are there any attorneys who have knowledge on how to structure deals with private lenders who want to invest in real estate with their IRA, 401K, savings or stock, etc.  

I was uncomfortable but I thought that maybe this was the way commercial deals worked.The GP predicted selling the property for $3.1 and then signed a deal in January for 2.78, which seemed low given the hot nature of the market and the improvements done to the property but I didn't really have any recourse.

Seems to me that if the seller doesn't need the money they would potentially make a far better return on their investment by using seller financing vs putting it in the bank or investing it in mutual funds or stocks.

You can start up a business, you can try your luck in the stock market, you may inherit money from your family, etc.

I've been investing in the stock market since 2003 and I bought 4 buy and holds in Hendricks county from late 2007 thru 2010.  

FHA guidelines allow using collateralized loans (i.e. your 401(k), stocks, bonds, life insurance deposits, other real estate) but not anything that would increase your monthly obligation - so private loans, signature loans, etc. are all out for FHA.
