I think this principle applies to everything in life.

Quote from @Karl Kauper: The tenant should figure his own life out.

With some of my clients, I've seen discounts of 30% to 90%.Here is a real-life example: I invested in a $50K note; it was second TD but with significant equity (over $200K) protecting my investment. 

That being said, life happens, and the mortgage police are not going to come looking for you if something unexpected happens and you have to move out of the house before one year.

Our portion out-of-pocket was the $3K deductible.I'm friends with numerous apartment owners. 

Just saying it is just a speculation doesn’t make you go anywhere in life. 

My team is also well connected to this sector of the industry allowing us to be experts in Land listings as well as have access to numerous Off-Market Listings.

The sad stories of money lost are too numerous to ignore.

Do that every 2+ years, sell tax free, repeat, and you can be set for life ("live in flips"). 

As for my Airbnb research, I have spoken with a person who runs numerous Airbnb’s in a different area (city atmosphere) who provided good ideas on how to smoothly run the property.
