Make it easy for me.

The property is in Maple Valley, so no the situation of all the new rules that are been imposed for Seattle now.

Dealing with C class tenants are not easy for beginners like me.

Does anyone know how easy/difficult it is to change the house number?  

You pay for having quick and easy access.  

First, I would check the actual reserves of the association, usually pretty easy to find out in the buying process (required resale cert etc).

Seems pretty easy to obtain.

Am I saying PMs (and managing agents) aren't any good, its easy, they don't earn their fees??  

Finding a buyer will come easy.

A good "one stop shop" with a solid track record (make sure said track record is apartments and further same type asset you're purchasing) in the given market should be easy to find with some diligent investigation.
