The economist in me thinks that you should shut down the business that is barely making it and focus on the two that you are getting better yields from. For the record, I am glad that you run businesses and are spurring economic activity. Good luck with the ICE, to hear my local talk show host tell it - anecdotally, I'm sure - "The ICE doesn't really want to do their job because it's some kind of government conspiracy to overlook immigration as a problem."
By the way, I live in South Carolina. The town where I live has a little higher than the median home prices in America ($208,500) for 3 BR, 2 BA homes; right around $224,100 according to Sperlings. And, for the record, I'm in one that's about $50,000 less than the mean...and I'm okay with that.
