Try not to get emotionally invested in any property.

Keep your emotions bottled up, this is business, it is not personal.With that said, do your self and any potential buyers a favor and complete your proper due diligence first.

The emotional personification of true "passive income"- you still need to react to the world and make decisions, but if the team is good, it becomes pure joy to not have to think about daily routine management of a well-launched investment..

To be very blunt, when you start getting emotional (as referenced by your comment about your friends in real estate), you're about to make a really bad decision. 

@Denise HolderPeople usually over pay when emotionally attached to a property so beware.

I am one and am emotionally flat to a fault. 

Below is what I used to stare at all night (I worked 60+hrs a week during the day, slept when I could and traded the London session at night)After six years, I still wasn't very profitable and emotionally sick of the +/- $2500+ daily swings so I spent a day flying from out of country to Toledo, Ohio to have some beers with @Andrew Fidler (highly recommended) and didn't leave before putting a few offers in.It's hard to believe that was actually seven years ago. 

Again, the tenants have the upper hand right now, so kid glove approach and I hope that buys me some emotional capital so they continue to pay.  

Investors operate based on numbers, rather than emotion, which makes deal flow and analysis easy compared to retail buyers.
