FIRST INVESTMENT PROPERTY/DUPLEX W/TENANT OCCUPIED

[Adam Rego]

Hello everyone I need your help please.

Ok so I'm going to try and explain my situation . I'm in the process of closing on my first duplex which I plan on house hacking. I found out there was a tenant in one unit so I said ok that's fine. I asked  for a lease and was told I will get a lease at closing. So a couple weeks go by and I ask if I can get a lease since both parties agreed on a price and in the process of going through with all the paper work.

I then find out that the tenant isn't paying rent and there is no lease since the owner of the property died back in 2014. The decease owner's heir takes over the property and has let the tenant live on the property for free as long as the tenant agrees to take care of it. As a new investor I would like some advice on my rights as a new land lord. If the present tenant does not agreed with my new lease agreement can I call the sheriff on her to make her move out? Can someone help advice me in this situation? My closing date is November 4th, 2016.
