The law firm says for now they are presuming registration is required.

Mehran,Property EquityLogic suggests to me the lenders would have a higher interest in foreclosing on properties with a higher equity position for two reasons: 1) the impression the borrower would be more motivated to obtain new financing and payoff the present lender, thus, saving the present lender time and money; and 2) a property with more presumed equity would be easier to dispose of should it become an REO.If this is what lenders are doing, I do not know.One thing I do with my borrowers and recommend to people who are offering seller financing, if the possibility exists, it is a much better business decision to renegotiate the loan than the long and costly process of foreclosure.

Scenario:SDIRA purchases a note at a severe discount to face valueManager of SDIRA breaks the note into two pieces: The first X payments and the remaining Y paymentsSDIRA sells the first X payments to another passive investor to recoup the value of their initial investment in the notePresumably the process is repeated thereafterSo this is really a proxy for "financing" and presumably avoids UDFI and possibly UBIT for lucrative investments held inside of a SDIRA.  

REITs aren't really tax efficient, though, unless you're using a retirement account, and presumably that is not her situation.You could look into turnkey providers.
