Office Building Management Costs

[Michael Willis]

Hi all, I am looking into buying a 16,500 sq ft occupied office building.  This would be my first office building holding. The listing doesn't provide a management fee. What is the typical/expected management fee for an office building of this size?  Are there any programs you can recommend which will automate most everything?  I know there are many but finding the best one for this application could save alot of expenses
