I am considering buying a commercial property in Colorado and am wondering if I'll have to honor a lease that is with an illegal immigrant. 

Maybe there is a new immigrant population that has flocked to the area.

Almost of those younger inhabitants are white and quite a few of them have anti-immigrant views.

My wife and I are both 1st gen Americans from Slavic immigrant parents and grandparents.

I think your renter base will mostly be immigrants. the area is near white center which is mostly a C- or D hood.

If you really want to get accurate with your return then take ordinary income tax from the $15K which including self employment tax will run you almost $7K so you'll end up with an $8K profit at best.And  yet even more potential bad news - Depending on your immigration status you will be  subject to FIRPTA withholding of 15% of the sales price of the new property.

Sorry dude, you have the added burden of being Asian with (probable immigrant Asian parents).

They are first generation immigrants from India and it is clear that they will be preparing traditional Indian foods in the home, including curry.
