Even if it had park owned homes you would have to develop a system or have more local help especially with full time employment.  

You may be in an area where many people work for the same company lets say that has in that area traditionally employed a great number of people and then suddenly laid off a high percentage of their work force and perhaps allot of people in your area will be motivated at that particular time to sell their house and move on with their lives.

So number 3 of the exception says:(iii) a regular salaried employee of the owner of real estate who performs property management services with reference to real estate owned by the employer, except that the employee may only manage real estate for one employer; So I'm not very familiar with legal jargon, but if I understand this correctly I could act as a property manager if my friend hired me as an employee, but I could only manage for him.

 #3  You should ask them for specific landlord and employment references if you have not already.    

keyword = SHOULD :)  if you do things correctly there is no need for double closings which quite frankly, is a real newb way of doing businessif you're not 100% about this or that, employ the services of a real estate agent/broker/realtor.  

The owner is currently employed.  

Lots of rules but basically you need a project that will employ enough people to qualify.

Though something always comes up I currently am not working and have no promise from an employer of future work.

I am currently employed and although it is a low salaried position, I do enjoy what I do and the potentials in growing and advancing as things grow. 

I wouldn't employ this technique more than once - do some research into the going rate for comparable rentals and then post the property again with the appropriate market-rate.As for denying the dog, make sure it isn't a service animal.
