Services income is taxable to an IRA as Unrelated Business Taxable Income.  

Would I be able to reduce taxable income with multi?

Once you put a property into a Sub S Corporation you cause taxable events when you pull them out, so many keep using them. 

@Yoshi Uem,The first question to ask is whether your residential real estate activity is showing a taxable income or loss, and, approximately how much annually.

If you're qualified to open a solo 401k, I suggest you look into such option instead to avoid having taxable income. 

In taxable stock accounts, the securities investor must worry about giving back some of his gains through payment of capital gains and state income taxes when he or she "rotates" the investments in his or her portfolio.

I would imagine it would increase the taxable value and a lot and people would get upset about having to paying more in taxes.I prefer a home with a finished basement because it will typically yield a home with twice the space for the same cost and also usually makes it easier to work on the foundation along with electrical and plumbing.

According to the little that I have read on this subject, the 20% pass-through deduction only applies if the taxpayer has a taxable net rental income.  

This stipend is my only source of "income," and is not reported on a W-2, but the entire stipend is taxable as the stipend is used towards educational expenses. 

It will be certainly be fully taxable as with any other rental activity and there may be some additional reporting obligations if you maintain a foreign bank account.You will need to know what foreign reporting obligations (tax & non tax) you may have (if any).
