House Hack Rental Agreement

[Tiffany S.]

I brought my personal home in July of this year. There are 4 bedrooms. I have a room and my 2 kids have their own room. I rent out the extra room on the other side of the house. There is also a den/play area that I am considering making into a room to rent out due to my 6yo going to live with is dad for a while (all it would need is a door and some free standing closet space maybe). 

So my question is, do you all make your renters sign a rental lease when house hacking? Do you require background checks? Does anyone have an example rental agreement I could use? My current renter came from Craigslist. Didnt do any type of verification. She's been pretty cool, but I do not want to chance it again.
