The real estate is effectively inventory in a sales business, just like refrigerators or stereos.Passive sources of income such as interest (i.e. hard money lending), rents from real property, dividends and royalties are not subject to UBIT.This concept is documented in IRS publication 598.The ROBS program is an entirely different structure as compared to a self directed IRA.  

I'm really just looking to maximize return here.I have a very comfortable savings/investment balance of $100k+, so secure financially.I am not handy and not looking to "buy a job."

I am calling all my local banks, I have a close to perfect credit score and other debt free real assets to use as security.

Which means learning how to identify using public records the most likely candidates that would be willing to sell. 

I can't imagine banks being anxious to publicize their troubled loans.

(See JD-HM-7 on page 15)Here is the link:  https://www.jud.ct.gov/Publications/hm014.pdfAnd looks like it describes the process you're looking for. 

From there you want to check public records for upcoming auctions and do research on properties.

In my property that essentially has tree logs holding it up, there was later added some bracketing to secure the vertical log to the horizontal beam.

Definition I found online - A due-on-sale clause is a clause in a loan or promissory note that stipulates that the full balance of the loan may be called due (repaid in full) upon sale or transfer of ownership of the property used to secure the note.

My real estate goal is to become a successful real estate investor in order to secure my future.
