Usual property management / maintenance charges

[Paras Newbe]

hello,

I am working with a property manager for a property I may possibly buy in Austin (Still researching). Below are the rough charges.

1) 70% of the first month rent for every new tenant.

2) 7% of each month rent after after first month 70% charges.

3) 10% of the maintenance cost will be have to be paid as a maintenance service fees.

I am little worried about number 3 above. Any feedback? Doesn't usually number 1 + 2 covers "maintaining" the property too?

Thank you.
