Tenant paid last month - can I evict for unpaid rent

[John Tatum]

I'm I'm having a very tough time finding an answer to this question. I'm in the state of Florida and I have a one year lease with a tenant who has paid first month, last month, and security. We are in the fifth month of the lease and the tenant is not able to pay the rent for this month. Can I still evict even though I'm holding last month's rent?  Or do I have to apply any prepaid rents before they become deliquent?  Thanks in advance.
