Quote from @Miguel Del Mazo: Thank you for the discussion @Corby Goade .I feel like we are biting off big pieces of a complex topic, and I think it would be helpful to focus on either the interests of the property owner or the MTR operator to simplify things,I think your greater objection to MTR arbitrage lies with why a property owner would want to willlingly enter into the agreement, so I will focus my reply on that. 

Padsplit is a topic of discussion also (STR room rentals), but I think LTR's are a little more consistent with income and a bit less work.

I suggest that you view my podcast on this topic. http://synergeticinvestmentgroup.com/2019/01/02/rod-khleif-student-housing/Please give me any opinion you may have on Student Housing?
