Then MEH, there could be a hundred reasons from the verbiage never transferred across some internet site, to the listing agent forgetting to add it, to the guy having not done anything with his license in years and just remembered he has been paying the $50 every two years to renew it with the state, but hasn't belonged to the board in years.

@Brandon Turner's book on property management is excellent.A great option, IMO, is to find a PM that will do "a la carte" style management.

I would not even have named the current occupant as styled the suit as: Myself vs Original tenant and all other occupantsA couple of other questions and observations just to help:-I would go to your profile and change it to just your initial so this thread cannot be googled by the occupant-Did you seek a monetary amount or just possession? 

it Hasn't been my experience that there are additional certs sold each year, at least in the two counties I have purchased in.

Consider him to be your next/only tenant when screening.It is a major newbie mistake to only consider the qualifications of a existing tenant when taking in a additional person.

I suggest you get an average for the past year, increase the rent by that amount + 10%, and just add it to the rent so you don't have to think about it.Once exception: I put a cap on how much is "included" with the rent.

We also ended up selling it as a for sale by owner with both parties which kept an additional $30k plus in our pockets.Lots of people we talk to think that we we're lucky and maybe we were on a few things like selling without an agent but I still think that you can put in more money to get more money out.

I would imagine he is referring to being all in (purchase + repairs) up to 80% of ARV (in addition, maybe he has a lender who will loan up to 80% LTV).

Now I have taken an addition line out on our house and wondering what is best with using this money for purchasing another property? 

Speculation isn't investing (it's guessing with style), and rationalization is very expensive.
