Tenants have extended guest!

[Antea Alexander]

Ok! So I own a duplex and I live on one side. I am a minority so I say this from a good place. We rented the other side to an Ecuadorian family of 5 (husband, wife, and three kids). For the last week I have seen a family come here every night with there kids. They leave during the day and come back at night. It has been 6days of this behavior. I believe they are sneaking around. We explained that if they have any other guess longer than 10 days then they are to be added to the lease.the tenants already pay high rent in New England but I feel like I need to address this asap lo 10days
