Not giving any legal advise here but the local laws require someone within a local phone call to be a contact person for a rental property, with that being said.... it does not require it to be the owner or a realtor. Your friend down the street can be the contact!
You can hire a lot of things without hiring a licensed realtor such as a secretary, customer service representative, an advertising specialist, general contractor, cleaning service etc.
A good example is wholesaling, by its title it is not allowed in PA but contract assignment is?
The original post was over two years ago in which I have become an employee of a company that manages its own properties.... yes, an employee..... not what I wanted but it has enhanced my skills and enabled me to learn more about real estate then I could have from a book. The relationship I have with the owner of the company was several years in the making and I wouldn’t do what I do for anyone else in this area!
