How to prevent my tenants from running off?

[Patrick Philip]

I rent in Florida. At this point, there is no way for me to prevent my tenants from vacating prior to the expiration of the lease. The only thing I could think of was to not give them their security deposit back if they didn't complete the term, but according to Florida Statute 83.49(3)(a) and 83.49(5), I still must return their deposit minus any claims.

It is cheaper for me to let them leave than to file any evictions in court.

I did notice that in the first paragraph of 83.49(5), it says "except when otherwise provided by terms of a written lease..." Does this mean that I can include a clause that says if they vacate early, they will not get their deposit back?
