Tenant only gave 1 week notice to break lease?

[Thomas Harris]

Hi everyone, I would love some help with this. I have a tenant who still has 8 months left on his lease. He recently informed me that his mother has fallen ill and he needs to move to Texas to take care of her and he would appreciate if I could let him out of his lease early. I told him I understood and was willing to work with him, and told him to give me a written notice of his intention to move out. He emailed me one a few minutes ago that said he will be out by February 9, 2023. That's only a week away. In the state of Florida, I read that a tenant on a yearly lease must give no less than 60 day notice to move out, and is responsible for 60 days of rent. But I also read that the tenant is responsible for rent until a new tenant is found? Which is it?

How do I handle this? He has a $1200 security deposit...do I use that to cover the rent until a new tenant is found? The market has been very slow here for the past couple months, so I don't have much hope in finding a new tenant quickly.

Also, if somehow I rent this house before the 60 days are over, do I refund him the rent? Or prorate it? Hard to find info regarding that situation.

Any advice would be greatly appreciated!
