Post completion.
The former owner didn't leave any keys for the outbuilding which she used as a work studio but which I'm hoping to use as a bedroom. There are two doors to the outbuilding. She claims she never "needed to lock it" and she doesn't know if she packed the keys and if they'll ever show up.
Also the front door has two locks but she only left the key for one of the two. She says she never used the second lock.
I'm concerned mostly about the outbuilding. Can I get her to pay for the locksmith to replace the locks to the outbuilding and would it be her responsibility if she can't come up with the keys?
