Can I pay for the service outside of my SDIRA so I can use that service for both my SDIRA and my other note or do I essentially have to have and pay for two CRMs in order to be compliant with SDIRA rules? 

If you listen to the podcasts that are on this site particularly podcast 109 you will get a lot of good information regarding what you need to have in order before you start.I use a company that is owned by one of the Rich Dad advisors and they take care of everything and make sure I stay compliant.

Best way to find out is to call your municipal  and county finance office and describe what you intend to do.One caution, operating a rental without a business license if required can mean trouble if you ever evict a tenant and they may not allow you to obtain a judgment for damages if you are not compliant, not to mention a fine.

They will guide you on the process and ensure the loan is compliant.  

It would be compliant with state laws concerning equity and foreclosure, which need to be addressed state by state.

@Brian Gibbons I am looking at the Simple Man's Guide and was wondering what you mean about it not being Dodd Frank compliant?

Also, if you read the BBB compliant it states the Run My Credit Report is selected by default instead of having the renter opt-in for the credit report, which we believe would be a better business practice.  

We only rent to own, and seller finance Dodd Frank compliant.  

Search on originating notes dodd frank compliant.  

You’re buying peace of mind, boots on the ground experience, buffer between you and the tenant, assurance your home is compliant with local housing laws, and so much more.
