I am currenty renting a house in central Fl. I am looking to buy a house and need to then break my lease. What do I need to do to ensure that I am going to get out of the lease without any problems?

The easiest thing to do is to pay off your rent for the remainder of the lease period. Buying another property does not negate your obligation to pay. You could ask to be released or try to find a sublet if the owner would allow. If you move out early you are legally responsible for the rent until the LL finds another tenant, you pay for his advertising costs to boot.

Worse is, being in Florida, the landlord is not required to make a good faith effort to find a new tenant. So you could find yourself on the hook for the balance of the lease.

The ONLY way you will get out of this with a minimum of problems is by negotiating with the landlord. You can try negotiating a buyout (generally 2 months rent). If the lease (or the landlord) permits you could try a sublet or you could try to find a replacement tenant.

But buying your own home does not allow you to break your lease. So you will need to reach an agreement with your landlord if you don't want to be on the hook for the balance of the lease.
