Plans and things change unexpectedly.

This skill will serve you well whether you follow the rest of Dave's advice or not.Be sure that you have the cash reserves necessary to protect you from the unexpected.

Then, I couldn't stop clicking -- It was like looking at a bad car accident on the highway. 

@Julie MarquezYes, I agree there will be unexpected expenses, things that are out of your control..

I likely wouldn't do what I'm doing if I wasn't able to get on a plane any minute and go straighten things out over there as needed. and I keep plenty of cash on hand to deal with the unexpected eviction, sewer backup, and blown furnace that I know I'll have to deal with some day.

Rehabs can have unexpected issues! 

I would venture to say that more homeless folks die from exposure in NYC in one month than die in all "sub standard housing" accidents/fires/incidents in an entire year in the entire USA. 

However, I agree that sometimes it is better to have security in the cash flow, although that faster pay in 15 years, it could be better to choose the 30 years because it allows you to cover unexpected expenses or that additional money can help you to invest in other properties.

Training and experience will help to minimize overreaction when faced with unexpected road blocks.

Airbnb is trying to put lipstick on a pig here, and it's no accident that this experiment in taking place in a place like Oregon.
