Common legal issues for owner-occupied property

[Katie Douglas]

Hello!

I am new to the group but have been lurking for a while. My fiance and I are planning on purchasing a four-plex sometime in the future as our first property. We plan to live in one unit and rent out the others. I've read various things on the forums about legal protections for landlords, but are there specific things we should prepare for if we live in one of the units? It seems like various legal structures and policies for landlords are geared more towards businesses that own properties. 

Thank you!
