I remind my tenants that when they complain about roommate disagreements that they are all responsible for the entire contract amount and that they are the ones that are responsible for figuring out how to handle internal problems.It's been my experience that renting to roommates or students can go very well as long as the landlord is willing to clearly articulate what the duties of the tenant and of the landlord are.

My guess is they could be international investors that need to park their money somewhere stable or people betting on further appreciation?

I wouldn't pay more than $2,000-$3,000 for any program, unless it was very targeted and sophisticated like developing international timeshares or something like that.There are more things to learn than most people know.

I currently have a single family house that I am house hacking and renting well to Disney interns while living there.

@Bernie Liew not the same Bernie that interned in Syndicated and Leveraged Finance at STRH right?

And if your policies don't specify arbitration before legal action then they should. 

If you're ever interested in learning more about lease options, I teach it for free to my interns who want to take a crack at it and learn the system before venturing out on their own.
