Here's the deal, I'm wholesaling a property and there are some unsavory occupants. The homeowner still lives there and desperately wants to move. About a year ago, she let an older man and his wife stay for awhile. They later moved in 5-7 additional family members. None of them are making any effort to leave. 

The house is not fit for human habitation. it dirty, hoarded, infested and the whole place needs to be gutted. There is a small child and an older disabled man living there. It terrible really. the electricity doesn't work on one floor, the kitchen is filthy and infested. It's not a good place to live. 

The owner and her boyfriend feel trapped. They really want to sell but no one is going to buy it with these people inside. they don't have a lease they don't pay rent, they steal from the owner and make the house generally unsafe. 

What are my options. I know that I can't evict them because they don't qualify as tenants. I don't want to have to go through a lengthy ejectment process. 

Can the owner change the keys and turn off the utilities? It's her house and they are in her name. She's been paying for everything.  

Will calling child protective and services and adult Protective services do any good? I don't want to have anyone family taken from them but they don't seem to worry about them living in an unclean place.
