Are we paying our property management agent too much?

[David Barnett]

Hi Guys really appreciate your time and help, I am new to the real estate business, we recently bought into the property market in Ohio with 3 multi units with approximately 50 units in total.  Are the following charges normal? 

The agent wants to charge 7% management fee of all Receipts monthly, All Receipts are defined as follows: all rental income; all parking income, all vending and laundry coin income, all late fees and lease settlements, etc 

He also wants to charge 85% of one months rent for finding  new tenants? 

The Agent shall receive a project management and supervision fee equal to eight percent (8%) of the labor and material costs of any major capital improvement or major repair project, This fee does not apply to routine suite preparation and other routine maintenance/repairs.

Again, thanks for all your help guys.
