I've spoken with him on what we're seeing from a legal DD, and he handles more of the P&L proforma side

Can the  potential loss in per door revenue be absorbed if the cashflow is not there to cover operating costs for a specific time period?

I'm conducting research for an MBA project and am trying to do a bottom-up analysis of the residential real estate, property management market and what percentage of that market is comprised of properties with out-of-state land lords.The very specific question I am looking to answer is how many landlords own rental properties out of state, and how much do those landlords pay to management companies annually?

That's what I would use in MD, BUT not sure if there are specific requirements in Oklahoma City.

@Sam Peterson yeah, everyone will have an opinion here and it's important to know what's right for you specifically.  

If you are this close to the border or cost you need to purchase through a corporation or through a bank trust (Fideicomiso - Think of this trust to be similar to an inheritance trust or a living family trust in the US.)At all times you are the legal owner of the property, the best way to see it is as a permit or license that allows you to purchase, use, enjoy, rent, renovate, inherit, etc. a property in this zone.

Hey Jon,There are optional registrations that people can acquire, but I'm unclear if I'm legally able to request them.

That said, specifically what makes you want to pay a 3rd party for plan "compliance"? 

These tenants are on a joint several lease, and it's not obvious whether joint tenants can violate each other's legal right to quiet enjoyment given the unified nature of their rights and responsibilities. 

And of course this is all state specific..
