Early Termination Requested by Tenants

[Helen Zhang]

Hello, 

My tenant would like to terminate his rental contract with me and I would like to grant him that. I am interested in letting him pay 200% of the current rent. I don't want to call it a reletting fee as I do not expect him to pay for rent until a tenant replaces him. What would this fee called? is it early termination fee? and is there any template for this type of agreement I could use?

Thanks,

Helen Z
