Landlords fear expensive damages and liability of short term rentals.  

Fear leads people to want to be in control to lessen their anxiety and their fear.

or something else, I am still a newbie and its going to take some time before I understand 70% of all this, you now  made me re think my options here, it sounds like I still need to learn a lot about REI, but like i said I am more of a passive guy wanting some extra income, I salute and respect those guys who Jump at REI  without fear because they already done their homework.

I think my biggest challenge was the fear of F***ing up. 

More specifically, a tenant who was out of town, sent me a screenshot of a snapchat (social media for those of us who aren't familiar with snapchat) of fire trucks and ambulances asking if I was aware of what was going on and that she was fearful that the 4-Plex had caught on fire and burned to the ground.

Thanks @Alex Deacon and @Brie Schmidt  - I've taken your advise and contacted an attorney, the contract is very clear but I fear we will need legal support to enforce it. 

Gaining knowledge helps to take some of the fear out of the decision making. 

The fear is today the homes are way too high and if the market slows down the margin can be disappointing.

Stop living in fear, it gets better I promise, just make sure you run your numbers right.

It may not work for everyone but it has changed my life, just try it.Also on a side note, the more knowledge you have, the less fear will be present.
