Also be aware of Unrelated Business Income Tax (or UBIT) on leveraged real estate inside of an IRA.Or better yet, since you are self-employed - go with a truly self-directed Solo 401k plan, which would be a much better option and will help you avoid the UBIT on this investment.

For you, it will likely be business income / ordinary income(non portfolio) where it will be deemed active / passive depending on your level of participation.There are some court cases out there where people who originate 4 or more loans in a year are moreso deemed in the trade or business of lending money.It will depend on the original poster's taxaccountant to determine how he/she will treat the income.The one con of it being business income is that it may be subject to self-employment taxes.
