How do I vacate someone from my garage?

[Jade N.]

Hello All, I have a question...I purchased a property that has a detached garage in Baltimore City. The garage was occupied by a neighbor who is interested in buying it from me. At this point, my plan was to lease it to them until I could assess the situation. They agreed to renting it then refused to sign the lease. They want me to give them a deal because they made improvements to the garage prior to my purchase. I do not feel I should be responsible for anything done before hand. My issue now is, I have requested for them to remove their belongings from the premises. They are delaying. Do I have to go to court or can I remove their things? Legally, what am I allowed to do? Any guidance is appreciated. Thank you.
