@Phil P.Any debt instrument for your IRA (via LLC or otherwise) must be non-recourse per IRS rules. 

As used in this Section 17, "Interest in the Property" means any legal or beneficial interest in the Property, including, but not limited to, those beneficial interest transferred in a bond for deed, contract for deed, installment sales contract or escrow agreement, the intent of which is the transfer of title by Borrower at a future date to a purchaser.If all or any part of the Property or any interest in the Property is sold or transferred (or if Borrower is not a natural person and a beneficial interest in Borrower is sold or transferred) without Lender's prior written consent, Lender may require immediate payment in full of all sums secured by this Security Instrument. 

The Collateral paragraph says: All tangible and intangible personal property, including, but not limited to: (a) inventory, (b) equipment, (c) instruments, including promissory notes (d) chattel paper, including tangible chattel paper and electronic chattel paper, (e) documents, (f) letter of credit rights, (g) accounts, including health-care insurance receivables and credit card receivables, (h) deposit accounts, (i) commercial tort claims, (j) general intangibles, including payment intangibles and software and (k) as-extracted collateral as such terms may from time to time be defined in the Uniform Commercial Code.

Your support and encouragement have been instrumental in my success!

The instrument that ties the note to the property is either a deed of trust or a mortgage.

@Kalvin Wilburn conventional lending isn't more "safe" it's just a different instrument.

A deed is an instrument of conveyance and could have been done right or wrong.

He said that private money always says "Yes"Hard money is instrumental to our business as an acquisition strategy while we create or realize the equity.  

A lease and an option are two separate equitable interests in a property that use separate instruments.  

At the least expect an instrument clean from the Seller to the Buyer assigning the loan.
