Old fashion spring traps worked pretty well.    

I understand that rental payments for property owned by my SDIRA account (custodian, not LLC-type) need to be handled in an 'arm's length' fashion.

My firm is a good old fashioned brick and mortar accounting firm, and I still work with the great majority of my clients (even those that are local) electronically. 

The trust receives property, money, jewelry and it is a shelter against suits, defers taxes and has a checkbook for most anything but food, fun or fashion.

Or should i go the old fashion route, networking with people in my area and trying to get some sweat equity deals going that way. 

In a similar fashion, if you can imagine how much landscaping and underground infrastructure is in a golf course as compared to the clubhouse, that will give an indication of why an extremely high percentage of the property's value is allocated to the land improvements.

Your experience is valid as it pertains to you personally, however it seems like good old fashioned bad luck for one person to have that many cancellations.

Also, I've looked into the Quandl API but have found the documentation to be terribly out of date making it very difficult to use in an automated fashion. 

Call me old fashioned, but I think that slow and steady still wins the race.

My mom made a killing in real estate but hasn't run a number a day in her life so I am trying to follow in her footsteps in a more calculated fashion.
