What's the best software/way to collect rent for house hacking?

[Harshraj Thakor]

Hi, I live in Charlotte, NC and I am brand new to house hacking and real estate I have 4 rooms in my house to collect rent from and I am looking for the best software/way to collect rent/manage the property. I need a software/tool that can help me collect rent from 4 different tenants in the same property. Also, it would be great if I could get some suggestions on what website/tool to use to do background checks and e-sign lease agreements.  

And if you have any suggestions/advice for someone who's just getting into house hacking please feel free to put them down. I would love to gather as much knowledge as possible. Thank You
