beancounter,
compare apples with apples, a list of Q’s to ask each agent is a good idea. Ask them who their target is, what they will do to sell it, why should you choose them etc. Ensure their goals are the same as yours. Don’t pay any fees until they have sold it, get an itemised list of all fees/ costs.
A reduction in available properties has made it a sellers market from a point of view of what you can expect from your agent.
We’ve been on the Money Lender merry-go-round for the last ten years, its probably the same as with a Property Manager, find a good one to start with, establish a good raport with 1 person in their office and keep on their back if they are not providing the service you want/ expect.
