When to Hire a Property Manager

[Matt Rubin]

I'm planning on purchasing a rental property in the near-ish future and will most likely want to hire a property manager to take care it. Since A.) I don't have any landlord experience and B.) It will not be convenient for me to manage it myself my work schedule and lack of car. My question is when should I look for a property manager? Will they be interested in talking with me even before I have a property to manage? what is the usual process here?

Thanks!
