Tenant left 2 months into year lease. Do I owe PM new lease fee?

[Lois S.]

MF property out of town, managed by PM.   Tenants, after signing a 1 yr lease, stay 2 months & move out without notice.

- PM says Tenants will be liable for 30 days rent. I know CA law says tenant is liable for rent until a new tenant is found.

-I would expect tenants also to be liable for any make-ready expense.  Correct?

- Should PM expect me to pay another lease-signing fee?

PS: As background, I researched the prospective tenants' social media online & would have been reluctant to rent to them.
