Acquired tenant parking

[Sameul Ahsan]

I'm new to this and just purchased a multi family usinf fha. I will be living on the first floor with my family. There are 2 units above and one of them already gave their 30 days notice and it's okay. The other tenant I feel may be resistant to paying more since they have been paying half of the market price before. 

Tenant is at will in the state of MA. I would like to know. Can I legally tell her not to park in the driveway? I have 3 cars and there isn't room for her. She never signed a contract with previous owner and is at will. She has been parking there for 8 years but with owners changing, circumstance have changed.  Can I just tell her to start parking on the street ?
