Friend moving to Indonesia; first time over seas owner

[Martin Gaspar]

My friend bought a house while on sabbatical in the states from Indonesia bought a house and wants to keep it.  He's looking for management agencies to keep up with it for him while he's gone.

I've heard there are just so many bad management companies; with that being said, what should he look for in a good one?  Is there a review website with good, real reviews?

Thanks in advance.
