Assumptions are all attached in screenshots. 

I am not sure how this would work with loan assumption.

@Eric ChaseYes, your assumptions are correct.With a checkbook IRA, you have a two layered construct designed to provide a considerable amount of investing flexibility and control.It starts with an IRA account held by a specialty custodian. 

I made some assumptions based on a small amount of research.

There is an assumption that all will remain the same except the price of the property you want to buy will just drop.  

Once you get your units stabilized like he mentions in year 3 you now need to have an assumption in your model on rent growth from here on out in your hold.

The best deals are the ones underwritten with reasonable assumptions that the sponsor can explain and back up with data.  

I’m thinking verify rent assumptions with a property manager and ask for a P&L.

Unless you need tax deductions now I would use the SDIRA but make your assumptions and run the numbers and hopefully the answer is clear. 

Based on the assumption that you can get $800 a month for them it will put you at breaking even when cash-flowing.
