What kind of agent do you need?

Actually right now I have at least 15 that have PMed me

Are you looking for a property portfolio manager or a building manager?

These are 2 different persons and their scope of work is very different as well.

Building manager = Person that looks after the well-being and day to day running of a property, think of a Condo or Strata building manager. They need to be skilled in overall building maintenance, laws with regard to strata properties, managing people that does the maintenance and ensuring everyone that lives there pays up.

Portfolio manager = A person that mainly manages your investment properties. Tasks may include finding tenants, making sure rents are paid on time and attending to repairs that may be required from time to time.

Unfortunately both aren't easy to find if you are not willing to pay good money for them.
