Inherited Tenants: Addressing problems

[Moises Robles]

Hello Everyone, 

My wife and I are a couple weeks away from closing on our first Duplex in which we will be house hacking. One side is vacant and the other side is already rented out to tenants whose lease ends in 6 months. Our tenant and her mother are both on the lease, but during the process we noticed that the tenant has moved her boyfriend and his friend into the home. The boyfriend and friend both have big commercial pick up trucks which they park literally on the front yard  and the other is usually parked out by the road but right in front of the property so it’s covering the view of the duplex from the street. There is a driveway but it is already occupied by 2 cars, I’m assuming it’s the tenant’s and her mothers. So there’s a total of 4 vehicles on the property not including our own vehicles.

They also own 2 dogs in which they allow to potty all over the yard and do not pickup after them.

Because they are under the previous owners lease which does not mention anything about multiple cars around the yard or picking up after the dogs, 

How would I go about addressing this situation with them?  

I appreciate any help!
