Tenant wants to transfer lease after 4 months

[Lynzie Mackey]

We recently rented our first long term rental and got a message from our tenant that they had a family emergency and that they needed to get out of the lease after only 4 months.  I reviewed the lease which states that they have a buyout fee of two months rent or $3200.  Two days later, they told me they have family members interested and are wondering if they can transfer their lease to them given they are qualified.  Should I charge a fee to transfer the lease?  Should I send a cleaner in between move-in and move-out if they are qualified?  What policies do you have?  Can I start a new 12 month lease with them or do they need to take over the existing lease terms?
