Property impound fees

[Stone Teran]

I bought a new apartment building that has an existing property impound sign with a towing company that went out of business.  I called a new company and they are anxious to put their own sign up but said they will charge me $65 per tow.  Ha!  In my limited experience, the impound fee should always be zero to the property owner since the tow company makes money off the cars they impound.  True or false?
