Hiring a handyman/leasing agent???

[Ryan Moran]

Hi everyone!  I have a quick question regarding hiring management while I'm out of state. 

I have an acquaintance who is an experienced handyman and a true professional.  I ran the idea of having him fulfill some management tasks for my two occupied rentals after I move out of state and he responded very positively.  He'd be responsible for periodic inspections, taking pictures during turnovers, any minor repair calls, and showing the property when my current tenants leave.  So my question is this:

What should I reasonably offer him for his work?  Pay him per house call?  Pay him per showing?  Per signed lease?  Anything I should definitely do or not do?

Thanks in advance!!! You're all wonderful.
