Looking for non-senior affordable housing in Central Florida

Hi, I am 21 years old, I make $900 a month on disability and unable to work jobs to make more. I need a new place to live. My parents forcibly moved me to Pennsylvania so I’m unable to tour homes in Florida. But I need to get back there with the rest of my family and more familiar surroundings. I need a place with either $500 or less rent per month, or $6000 or less to buy (the money i have saved up). I don’t care how small. All the housing seems to either have a 2 year waitlist or for 55+ year olds only. Please help
