Management Co -- How much work do I do?

[Dan Griffin]

Assuming I hire a management company to handle property, how much work will my property be? How often will I have to be involved with issues?

In addition to the property management fee, what have you folks found is a good number to estimate for monthly maintenance expenses?

Do any of you handle tenant screening yourself, but allow someone else to run the day-to-day operations?

Just looking for experiences. (We are not yet landlords, but strongly considering it.)
