Tenant moving requesting sub leasing - sub renting

[Seth Rouch]

I have a house with 3 tenets, all friends. One of them (strongest credit/renter) needs to move for her job. She’s asking if she can sub lease her room (rent it out to someone she knows or finds) for the remainder of the lease. (Which yes, her lease allows) I’ve not had this experience yet so my thoughts are to say “Yes. With 1 month fee of your rent portion and provided the new tenant passes our screening process” (credit and background checks, employment and pay stub verification etc.). I’m curious to pick the brains of the BP community for their suggestions and ideas. Also if I said “no” she could then break the lease or worse etc. So I’m leaning towards “yes”. Thanks in advance : )
