I believe he is liable, if he provided an unsuitable living environment and made a profit doing so, wouldn't you agree if this was your home ? 

@Carl West I'd secure it to the property with a promissory note and a mortgage instrument. 

You can look the lease over, it may have things about dangerous instrumentalities, or acts that increase the insurance. 

You need to be asking them all about their habits, routines, work hours, do they have weird hobbies or loud instruments.

They are marketed as attractive options, but will result in you owing more interest at the end of the payment vacation and should be used as an instrument of last resort (and not for a trip to a sunny beach as they often are).

I only made a good judgement call because of Brandon and Heather Turner's book on Managing Rental Properties, it has been instrumental in doing our first deal!

Then from there I started to get my RE license to further my education.So here I am, a few years later and have my first deal under contract, struggling with financing, but all in fun of the game I'm still an active member of bigger pockets and tell all my friends and family to get on here and enjoy life a little more.To wrap things up, I would just like to take a moment to thank you and all of the staff at BP for this incredible instrument to improve the lives of thousands of people around the world.

I have family and friends with cash who are itching to get securitized higher yielding instruments, and selling the notes I have could be a great way to increase my returns and their returns.

To legally bypass having to pay the suit on his behalf, since the only instrument "forcing my hand" if you will was the nortgage note.

My household income allows me to save $20k post tax dollars a year and ~40k pretax dollars per year for allocation to real estate rather than stocks/bonds & speculative instruments.
