Answers:  A - To help the tenant pay for their rental expensesB - To have to find a different source of income (investment) to cover the negative income on this property...but you have no money now, or in the foreseeable future, to invest with.C - To rationalize that the property will be gaining in appreciation faster than you are losing cash per year.D - To put yourself in a "cash poor" situation, and making that situation worse by the month.E - To put yourself in a position where if you are in need of cash, you can always borrow the money, and as a result of the negative cash flow, need an added source of income to pay off that new debt.F - All of the above.

You'll probably try to say that when you pay the $190K you're actually saving the other $142K in interest over the next 29 years or some other wacky BS because you're immune to simple, rational explanations, but I'd be willing to bet that that math doesn't work out as well as this does.

@Michael Gansberg my rational brain agrees with your assessment of the impact. 

.: Well, you can't expect rational behavior from a crazy person!

I invested no more than I could afford to part with, I understand it, I believe in it, adoption is growing, and I could write another two pagesI think if anyone has rational questions, not emotional hate, post up and we can discuss things. 

The conclusions are inescapable to any functionally rational mind.

For me it's been hard to rationalize keeping the homes instead of just turning them for quick profits.

Assuming my converting the use of the property (from owner-occupied to vacation rental, or from traditional rental to vacation rental) is the highest and best use of the property, and assuming there aren't may people aggressively doing this in my target area, many properties are not rationally priced to market (short-term) rents, but rather far below it in many cases.   

-Aim to be reasonable with your finances, not completely rational.
