Rent question about moving out before end of lease.

[Lalo Alvidrez]

Hello all, new to all this and have read lots of posts here. So thank you for all the tidbits. My question is, I have a tenant who's lease is up at the end of June. She was asking about moving out at the beginning of June. I have another tenant ready to take over. So if new tenant was to move in say middle of June, would you charge the current tenant the full amount for june? Also need to address the issue with pets and carpet.  They have a good size dog and 2 cats and a couple of days ago I went by and the pet scent was heavy. I am planning on letting them know they are responsible for either having carpet professionally cleaned or replaced. Please give me your thoughts.
