property manager keeping 10% late fee

[Tim Bee]

The tenants debt is about $1600 and goes up by 10% every month because the property manager keeps the late fee.  Basically I am loosing 10% a month so it's like I (the owner) am paying the late fee.  I know I could evict and then sue bla bla bla....I probably would never get my money even if I win.  So my question:

Maybe just tell the property management company to waive the tenant's debt so I can finally stop having the late fee taken out every month?  If the tenant ever builds up another $500 or so in debt then I would evict.  Thoughts?
