am I allowed to accept a tenant who PREPAY several months in advance?

[Mary Joe]

Hi All

I have a tenant who is self employed and she just started her business, since it is difficult to establish her income, she offers to prepay 3 month  in advance for a 1 year lease.   So she will put down 1st 3 months, last month and 1 month security in order to move in. 

Am I allowed to do that with a tenant? 

I know there are some regulations that say security deposit can be no more than 1 month, but not sure if there are other laws the regulate whether Landlord can accept prepayment of rent in FL. 

Thanks.
