There are more than just a few ways to organize that type of arrangement but you may also be familiar.

Quote from @Ned Carey: However if they loan you the money from their IRA they don’t pay taxes on that interest until they take it out when they retire.Unless that person's earnings in this arrangement are subject to UBIT or UDFI. 

Personally I don't find the one side bar ad all that intrusive for a free app with the functionality this has... the biggest complaint is that you can't make sub accounts (i.e. 1 expense account for a property with sub-accounts for each particular expense type) but you can export directly to MS Excel and re-arrange and graph however you want there if you needed to a higher level view to show someone.Hopefully this helps others interested in the program... not bad for free :)

This arrangement isn't something every bank offers, so it's important to shop around and foster relationships.
