Property Management - Maintenance only contract

[Seth Golding]

I am a residential property manager.  I just had a inquiry from someone with 45 units who is looking for someone to manage all of the maintenance of his units, while he will continue to manage the tenants, billing, accounting. I usually charge a 9% fee for a full service management, so Im trying to figure out what a fair price for just the maintenance would be. Any managers, or investors who have thoughts on this would be much appreciated. -Seth in Burlington, VT
