It takes the emotion out of whether or not you should raise rents on your tenants and instead turns it into an applicable formula.

I would hope my landlord would respect the fact that I cause almost ZERO issues, and have the decency to inquire if for some reason my payment was late, AND even waive the late payment if it happens infrequently.Furthermore, I'm not marrying my landlord, so we don't need to be emotionally attached to the point of "relationship" beyond a business agreement.I think it speaks more to you and your attitude as a landlord that you would even consider charging a late fee for a 5-year, issue-free tenant who has never been late.

Appreciation is a tangible result over time of an intangible emotion, desire. 

Some people want to get rid of a property that's causing them distress (financially, emotionally, etc.) and they're willing to give up equity for that. 

They have a poor understanding of what it means to transact a property based on facts and numbers as opposed to emotions and dreams.Fire the agent, let her know you will not be referring her.  

PS: One thing I forgot to mention: DO NOT soft pedal issues that come up in an inspection (don't overblow cosmetics, either) because you've already become emotionally invested in a property.

REI is business and emotions are best left out, but man it is hard to just laugh it off when a couple hundred thousand dollars is sitting in a house, that we missed the spring market and now have to list and go through the process again 2.5 months later!

@Tom R. is correct and if it is a emotional support animal reject the application.

I help parents understand the emotional world of their child and how to slow down and connect with their child so that they can help their child organize their emotions.

There are still opportunities if you are disciplined and have a business model.
