Looking into landlord tenant law and local utlity procedures. 

Many tenants get spoiled by an owner landlord and are upset when their new PM landlord is following procedures.

Each state has a Division of Real Estate who oversees broker operations & requires broker's to adhere to incredibly strict accounting procedures, audits and care of all of this money that flows in & out of their hands that is that of the client's (you) or the tenant's.

Important things such as tax law, remortgage procedure and availability ( as we're not local), buying and selling procedures and so.

The procedures are different.

@J Scott has processes and procedures in place to allow him to manage his properties effectively in short period of time.

It has forced me to rely on others for help and to create systems and procedures for dealing with problems.

Here's to hoping you can outline the steps and procedures you took along the way.

Each has it's own internal policies and procedures, each has it's differing level of cooperation with housing providers. 

Non-payment of rentBreaking lease earlyAdding unauthorized tenants or animalsThose are probably my most common three, but they aren't much of a problem since I have policies and procedures in place to handle them quickly and professionally.
