@Stephen SawrieFirst thing you should do is sit down and research all of the rules that apply to SD IRAs and either print them or save them so you have the rules in hand as you investigate how you are going to derive income from your IRA.

Bonus depreciation is derived from the portion of the property's value with a 15 year depreciation schedule (or less).

the interest rate, from my calculation, is a derivative product of M2 growth.The Fed is just so stupid to print money too much in 2020 by a yearly rate of 40%, average growth is 6-8%. 

The original poster asked about tax benefits to be derived from a partnership LLC.  

What you have to do is use a derivation of the annuity formula to calculate the payment you'll make for a loan.

Some young guy comes in with a low ball offer and says "well the derivative value based on this new reduced tax ratio formulation that I came up with justifies this offer I'm making you".

If there were a potential lawsuit derived from property with 100% equity theres a higher likelyhood for a lawsuit to take that from you even though you would still have the debt on your primary home you'd potentially lose the equity on your 2nd.There's lots more I could type but can't atm...In my opinion i'd get a HELOC(no closing costs usually) and find a lender that will let you use that as a downpayment on some smaller properties. 

Usually, as in most states, exceptions are made for non-profits, Realtors, attorneys, etc.I would suggest that you contact the regulator and explain fully what you do and how and where your income is derived.

CLEAN AND SAFE - that's the key.The difference between you and me is that you are deriving pride of ownership by doing a beautiful middle class type rehab for low income rentals.

There is a large benefit derived from a good relationship with your title company.
