complaints from neighbor's noise

[Zaid Badabwan]

Hello friends

I have a rental duplex, and one of the tenants keeps calling me complaining that the other tenants has visitors parking their cars next to the duplex and making noise partying or socializing. This has happened several times, and this tenant keeps his phone off and I cannot talk to him so I have drive there about 40 miles to sort out the situation.

Please give me your opinion and suggestions. Is it my responsibility to run there or should the tenant call the police for the noisy tenant? How would you handle the situation?
