Your best move is to contact several management companies and get their fee schedule. They all have different fee strucures. So me things to look for are:
Is there a fixed monthly management fee (rented or vacant), or just when rented fee?
Do they have a minimum guaranted weeks to rent per year option, or just a luck game?
Will they rent your house to large guided tour operators, or only to families?
Pool fee, is it an in house company, or can you choose?
Cleaning service, again, in house or can you choose?
Do they have a staffed office on weekends and holidays for the renters?
If repairs are needed to the property, do they hand the key to the repair man and walk away, or have a staff member let them in and wait.?
Will they charge you management fees the times you personally use the house?
How will they handle when you find your own bookings?
Hope this helps out...
