All in all - owning a place to rent to other people is a business, and business decisions need to be made based on that cold hard facts and not on an emotional basis, unless someone wants to quickly go out of business.

That means making calculated numbers based decisions, not emotional ones.

Brandon Turner here on BP has written a few good books to help.Lessons Learned:  Never let your emotions get in the way. 

And the truth is, if the investment property was completely passive and you had zero connection with it, such as an arbitrary stock in a mutual fund, then I would agree not to get emotionally attached to any one investment.  

Self management works if you are local and can separate emotion from business.

One more tip – people remember stories that trigger their emotions.

Leave out the emotion, the lies, the manipulation, etc.

Once someone has paid, what to them is a good deal of money, and invested a good deal of time, and become emotionally involved with a particular mentor and his program, they’ll fight like hell to defend it.  

There is also an emotional side to owning a rental that landlords are subjected to.

Having a strong understanding of your "walk away" price (maximum you're willing to pay) gives you leverage and prevents emotional decisions.
