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.

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.

There are literally thousands of tourists who come here on vacation, have a great time and, acting more on emotion instead of any kind of financial analysis, buy a vacation home.

Its your house.The absolutely worse thing you can do is get emotion and start making demands.

Bob I think you are emotionally invested in this flip.

I analyze all business models and streams of income without prejudice and emotion involved.

No emotions just numbers.

I know we should remove some emotions from the real estate business, but would you have bought this home?

I wonder if they really are service dogs (which are usually well trained) or pets with papers (aka emotional support animals).

Obviously, there comes a time when the incremental impact of "just one more" approaches zero but the example you are giving while emotionally appealing, is quite bogus.
