Remember that you as the IRA holder cannot provide goods or services to the plan (direct or indirect).

These are called "nixies" in direct response marketing.I've done well by setting these pieces to the side and then skip tracing the ones that appeal the most to me, such as high equity, deceased owner, no probate case filed, good area. 

Would anyone be willing to share some of their rent-to-own specific marketing materials they use in direct mailer campaigns?

This includes direct labor as well as indirect labor, such as time spent shopping for materials or time spent maintaining the property once it is for sale.

My listing agent's company is in direct contact with the asset manager on this property, and she at first said "maybe they made a mistake." 

Acquisition Specialist with Charter Financial looking for private realestate notes also interested in direct contact with bank asset management for non performing loans

That is, to use a different metaphor, if you're throwing whole kettles of spaghetti at the wall trying to make something stick, you may need to select a more effective strategy.I wouldn't judge "massive" by volume rather by how much research is done prior to making ANY offers - so you're making the right offers on the right properties.There's a parallel in direct marketing: an untargeted mailing typically produces less than a 1% response rate.

I am no expert in direct mail marketing but there is something off with the 200 out of the 500 number.  

Giving this to the plan would certainly seem like providing a benefit.In @David Frol 's case, there is the mitigating factor that his IRA is only a 10% equity holder in the property LLC, and therefore that property LLC is not a disqualified party to his plan - but, that still precludes David from providing a direct or indirect benefit to his plan, and serving as realtor for the LLC partially owned by his IRA-LLC would pretty obviously be such an indirect benefit.
