The main challenge for many people is turning a home they have lived in for so long into a rental because they have emotional attachment.

Bob I think you are emotionally invested in this flip.

I'm buying partly because of emotional and partly financial implications.

The rush of emotions from quitting a job is like nothing else

I personally believe some say there are "might be other offers" because that brings out emotions.

I've told him numerous times he's making a mistake by letting his emotions dictate his business but he disagrees.

There is no one to relocate, no emotional attachment, its costing the homeowner money as it sits there vacant and deteriorating so its an easy argument to make for selling.

However, in residential properties you're also contending with another class of buyers who are not investors and makes purchasing decision based on personal taste, emotions, etc.

Tenant did no wrong, but has a lifetime of thoughts and emotions. 

My suggestion would be to find a good team that is familiar with real estate investors, and is familiar with how investors think, i.e they make decisions by the number, and not necessarily by emotion.
