As a property manager I can't tell you how many times I have had to instruct owners not to do things that are against the law in Florida. Absentee owners who try to save the management fee in almost every case I have been involved in end up paying more than the fee in tenants that don't pay, or they have done some illegal things like change locks on a tenant and end up paying the tenant 3 months' worth of rent (Florida law) - If you have to evict a tenant and the laws are not followed, you may find yourself losing months of rent.
I have an owner (From New York!) who tried going at it themselves. I have been waiting for 5 months now to take over their property and put a tenant in, but they changed the locks and didn't follow the law. The tenant didn't pay but they didn't do what the law prescribed and the home sits vacant while they are going to court. They have lost thousands of dollars needlessly, losing rent money and paying a lawyer to straighten things out. If you are nearby it is not as much of an issue, and even if you nearby your chances are a bit better.
