Shorter term, furnished rental

[Ray S.]

I have multiple condos I live in and want to start renting one of them out when I'm not in town for 3-6 month timeframes. I'll be renting it out myself. What do I need to protect myself? 

Do I need some kind of deposit, if so what % of the rent? What kind of rental agreement should I have them sign? What kind of insurance do I need to protect my belongings and condo from damage or theft? How would I screen the tenant? Anything else I need to be aware of?

Thanks!
