Looking for room to rent in town (Tucson)

I'm a 26 year old male and have been working as my dad's unpaid caretaker for the last few years, But now he is moving out of town and im being forced out on my own for the first time in my life.
I don't drive so I need to figure out where im going to live before I get back to paid work but will have money to cover a few months rent from the start and plan to start job searching as soon as I've found a place to live.
I'm looking to move in officially May 1st.
Though if id be able to move my stuff in earlier that would be wonderful.
I tend to keep to myself, no interest in throwing parties or being obnoxious.
I'm not picky, and am fully able to pickup after myself, am alcohol and 420 friendly, as well as LGBTQIA+ friendly.
I have a small dog that I would very much prefer to keep but if I have to find her a new home I will do so.
If you have a room you'd be willing to rent for around $500 a month or less please let me know.
