For me it was way too time intensive.  

This is very labor intensive and expensive.   

Airbnb can be very labor intensive.

Did I mention it was larger than a basketball???

Thanks for your response  Max Tanenbaum, I have to research the RUBS system as I don't know how that works,  Well, on the upside, even in Florida, this is probably the most AC intensive part of the year, so it may get better....  

We're talking basketballs dude.

You are allowed to decide exactly what type of person you want living in your house and being left alone with your belongings. 22k in credit card debt looks a little intense so thats a flag. more importantly, unless you are in desperate need of income from the room, I'd wait for the right person to come along with a compatible routine.

Filling a park is going to be cash intensive no matter which route you take.

If you have an extensive network of friends, family, business colleagues, neighbors etc to tap into, then you might make decent money in the first year.If I were you I'd definitively keep the job, for 2 main reasons: real estate isn't glamorous like it is on TV and as James mentioned most people quit, and realistically in the first year you won't be very busy unless you do time intensive stuff such as cold calling / door knocking etc.Trust me, you don't become a RE agent and all of a sudden the phone starts ringing non stop.

No reason for a landlord to bother having a lease if they have no intension of enforce it."
